The Art of the Precise Cut: Showcasing Unrivaled Accuracy

At Cauthorne Paper , "precision" is more than a buzzword; it is the very essence of our craft. It signifies a meticulous, highly controlled process that transforms wide master rolls of flexible material into narrower, perfectly dimensioned widths, utilizing state-of-the-art shear slitting equipment. This foundational operation is critical for preparing materials, whether for subsequent converting processes or for producing finished roll stock ready for immediate distribution or assembly. Our unwavering commitment to precision means achieving exact specifications, maintaining consistent quality, and adhering to the exceptionally tight tolerances that are paramount for high-performance downstream manufacturing applications.

The level of accuracy we achieve in precision slitting is truly remarkable. For the most specialized applications, such as narrow width slitting, our capabilities extend to tolerances as low as ±0.004 inches, producing widths as narrow as 0.375 inches. This exacting standard is indispensable for applications demanding precise measurements, particularly within critical industries like automotive and aerospace.

Human oversight remains vital; our specialists meticulously check machine work, ensuring that the speed and efficiency of automation are harmoniously blended with the unparalleled quality traditionally associated with hand-work. This dedication is reinforced by regular inspections and strict adherence to rigorous quality control standards, integral to maintaining this high level of precision throughout every stage of the slitting process.

The ability to consistently achieve such fine tolerances makes precision slitting a foundational element for high-performance end products, directly influencing their functionality and safety. When slitting is executed with this level of exactness, subsequent manufacturing steps proceed seamlessly, minimizing complications. This proactive approach prevents defects, significantly reduces the need for costly rework, and ultimately guarantees the reliability and performance of the final product.

The transformative power of precision slitting positions it not merely as a processing step, but as a strategic tool for achieving operational excellence and maintaining cost competitiveness.

Ensuring Quality in Custom Converting: Our Process and Certifications

Tue, 17 Jun 2025 14:02:00 GMT

At Cauthorne Paper , quality is the foundation of everything we do. For over a century, our team has specialized in paper slitting and rewinding, sheeting, trimming, die cutting, and more, delivering “precision and versatility with every cut”. We bring that same commitment to every order, whether it’s a large-volume roll or a detailed custom design. Manufacturers and businesses can rely on our paper converting services knowing we follow proven processes, strict inspections, and continual improvement at every step. In short, we treat your project as our own – ensuring the final product meets your exact specifications and our high quality standards.

Advanced Converting Services with Built‑In Quality

Cauthorne Paper offers a full range of custom converting services, from paper slitting and rewinding to die cutting, sheeting, and packaging. Across all these services, we use state-of-the-art equipment and precise methods to ensure consistent results. For example, our slitting machines use precision shear knives that deliver a “superior cut with a precision edge” This means every slit roll comes off the line with clean, square edges and exact dimensions. We can slit rolls to virtually any width (from 3/8″ up to 70″) and rewind them to customer-specified lengths and core sizes, always meeting your tolerance requirements.

Paper Slitting & Rewinding: Our customized slitting process lets us cut large master rolls into narrow or wide rolls with tight dimensional accuracy. We tailor each slitting setup to the material and specs at hand. An advanced inventory control system tracks every roll from receipt to finished product, so raw materials and finished rolls are “easily identified and monitored at every stage of the process”. We can apply barcode labels or custom tags to each roll so it’s traceable through your supply chain.
Sheeting & Trimming: Once rolls are slit, our sheeter and guillotine trim equipment cut sheets to precise lengths and sizes. For example, our guillotine trimmers can cut sheets as small as 1″×1″ with exceptionally tight tolerances. In fact, our guillotine can hold tolerances down to 1/32″. This level of precision lets us meet even the most exacting length and size requirements. After cutting, we offer custom finishing options – from ream wrapping and boxing to palletizing – to ensure each stack of sheets is packaged neatly for shipping.
Die Cutting: Our die cutting capabilities let us create virtually any shape from chipboard, folding carton, or corrugated material. We use CAD design and a Gerber sample table to prototype and fine-tune designs, then run them on our high-tonnage die cutter. The machine is optimized for quality: it offers a max tonnage of 550 tons and “excellent print to cut registration and stripping capabilities”. In practice this means printed designs align perfectly with the cut outlines. Whether it’s standard packing inserts or intricate shapes for specialty packaging, our die cutter delivers consistent, clean cuts run after run.

Our modern converting machinery, like this calibrated high-speed press, is kept in peak condition to guarantee precise output. Every cutter, slitter and shear knife is regularly maintained and calibrated so dimensions and registration stay on spec. When a project calls for fine tolerances (for instance, cutting decorative labels or precision gaskets), our calibrated equipment and experienced operators hit the mark every time.

Meticulous Quality Control & Traceability

Quality isn’t an afterthought – it’s built into our process from start to finish. Each job begins with a detailed review of customer specifications, samples, and any special requirements. We inspect incoming paper or board materials before they enter production, checking weight, grade and condition. Throughout production, operators follow standardized work instructions and record key measurements. At critical points we perform in-process inspections: for example, after slitting, we verify roll widths and edge quality; after cutting, we check sheet dimensions and stack counts. Finally, finished products undergo a last quality check against the original specs.

Key parts of our quality system include:

Systematic Inspections: Every batch is logged with a job number, and our team conducts incoming inspections on raw rolls (confirming the material grade and dimensions) and outgoing inspections on finished goods. Checklists are used at each stage to ensure nothing is overlooked. Our operators have earned praise for their diligence – as one manager noted, the team consistently meets customer requirements “efficiently and with minimal waste”.
Documentation & Tracking: We use digital job-tracking software (PaperSoft) to document each step of production. This means every order has a paper trail, from the original purchase order and material certificates to machine settings and inspection results. We label finished rolls and sheet bundles with identifying barcodes and packing lists, so the origin and details of every item can be traced instantly. This chain-of-custody approach is especially important for customers requiring certified or recycled materials.
Equipment Calibration: All cutting, measuring and testing equipment is on a strict calibration schedule. For example, our measuring gauges and width sensors are checked against standards to maintain their accuracy. This complies with ISO 9001 practices and ensures that what our machines tell us matches reality. If an instrument or blade drifts out of spec, we recalibrate or replace it immediately. This way, every operation, slitting, sheeting or die cutting, stays true to the tolerances we promise.
Continuous Improvement (5S, Lean): We maintain a lean, organized shop floor. Workstations are arranged for efficiency (5S principles), tools are labeled and easy to find, and any process changes are documented as new standard work. This consistent organization reduces errors and variability. In fact, we’ve brought outside experts in-house to help refine our processes – like our Lean Six Sigma Black Belt, Tom Zbell, implementing things like work-center instructions and set-up reduction because as one industry advisor put it, these successes “show that Mark is serious about providing a top quality product to his customers through continuous improvement”cauthornepaper.com.

By combining these controls with our skilled, long-tenured workforce, we deliver remarkably consistent results. We treat each converted roll and die-cut blank as if it were destined for our own product , the same high standards apply.

What Is Custom Paper Converting? Tailoring Solutions to Unique Packaging Needs

Wed, 28 May 2025 21:57:20 GMT

Custom paper converting is the process of taking raw paper materials (usually large “parent” rolls or sheets) and transforming them into precisely the sizes and formats a customer needs. In practice, converting means cutting, trimming, rewinding, and otherwise modifying paper so it’s ready for use in packaging or manufacturing. Rather than selling standard roll or sheet sizes, a custom converting partner customizes the material. For example, a converter can slit a jumbo roll of kraft paper into narrower rolls or sheet it into panels sized for your machine. In short, converting turns generic paper products into tailor-made solutions for downstream processes.

Converting Services: Slitting, Sheeting, Trimming, Labeling, and More

Custom converters offer a range of specialized services to meet unique packaging needs. Precision equipment is used at every step – from slitters to sheeters to guillotine cutters. For instance, converters use guillotine-style trimmers(as shown below) to trim stacks of paper with clean, square edges. These machines and others ensure each cut is accurate and efficient.

Slitting

Cutting wide paper rolls into narrower rolls of specified width. Slitting tailors the material to fit specific machinery or packaging requirements. Large “master” rolls (for example, 80″+ wide) can be cut down to any needed width. This reduces roll weight and waste, making the material ready for your equipment. (As one converter explains, slitting “prepares raw materials for your machines,” matching roll widths to production needs.)

Sheeting

Cutting rolls into individual sheets of a precise length. A sheeter pulls paper off the roll and slices it into flat sheets at exactly the requested dimensions. This is crucial when downstream processes (like printing, lamination, or folder-gluer operations) require specific sheet sizes. Sheeting ensures uniform, stackable sheets – for example, cutting a roll into 28″×44″ sheets for the printing industry.

Guillotine Trimming

Using a heavy-duty blade to trim stacks of sheets to finished size. After sheeting, converters often use a hydraulic guillotine cutter to make very clean, square cuts. Guillotine trimming is also ideal for jobs the main sheeter can’t handle (such as extra-short runs or boards thicker than the sheeter’s capacity). This yields paper or board stacks with perfect edges. Some converters even bundle the trimmed sheets in uniform packets for easy handling.

Labeling

Applying identification labels to rolls or bundles for traceability. Converters can print or apply labels that include information like product name, roll length, batch number, and order details. Clear roll labeling prevents mix-ups on the production line. For example, one converter notes that all slit rolls are labeled with product name, length of roll, PO #, Roll ID #, date of manufacturing. This means when your operators load a roll, they immediately know exactly what it is and how to use it.

Packaging Customization

Preparing the finished sheets or rolls for shipment or use. This can include bundling stacks of sheets with banding or shrink-wrap, wrapping rolls in protective film, palletizing, and more. The goal is to package material securely and conveniently. For instance, slit rolls might be palletized with no overhang, strapped /banded, and wrapped in shrink film. Custom packaging (shrink-wrap, bags, slip sheets, etc.) protects the paper and makes handling at your facility much easier. .

Each service is adaptable. A good converter will work with your specs – handling everything from very large runs to one-off prototypes – and combine these services as needed to create the right finished product.

Materials Commonly Converted

Converters work with a wide variety of paper and board materials. Our common substrates include:

Kraft Paper (natural or bleached) : Strong, uncoated papers used for bags, envelopes, tape backings, and corrugated facings. Kraft is a workhorse material for packaging and industrial uses.
Newsprint and Bond Papers: Lightweight, general-purpose stocks (often recycled) for everything from interleaving to printing.
Linerboard and Chipboard: Heavier paperboards used in box making. Linerboard is the flat paperboard for corrugating; chipboard (also called binder’s board) is rigid board used in shoe boxes, appliance backs, or other industrial packaging. Converters can slit and sheet these thick boards for your needs.
Waxed and Poly-Coated Papers: Papers treated with wax or plastic coatings for moisture, grease or chemical resistance (think oil-barrier bagging paper, for example). Converting can slit or sheet these specialty papers just like regular paper.
Release Liners: Silicone-coated paper used as backing for adhesive labels and tapes. Converters often slit release liner rolls or make smaller sheets to feed label presses. In fact, one converter explicitly lists “release liner” among the substrates it handles.
Coated and Specialty Stocks: Any sort of coated papers or boards (like SBS C1S / C2S clay-coated board, CUK board, glossy or matte paper, etc.). These are common for graphics and packaging, and converting partners have equipment to cut and rewind them without damaging the coating.

In addition to the above, converters can often work with synthetic or composite materials (foils, laminates) and non-wovens if needed. The key is that they match their equipment and processes to your material.

Solving Real Packaging Challenges

Custom converting shines when off-the-shelf sizes just won’t work. Some illustrative examples:

Scaling Down Jumbo Rolls: A paper mill might supply a single 100″ wide roll, but your press or laminator only accepts 50″ rolls. A converter will slit that giant roll into two 50″ rolls (or more if needed). This maximizes yield and eliminates excess trim waste. For instance, converting can turn an 88″ kraft roll into 4 narrower 22″ rolls (with minimal leftover trim) so each fits standard equipment. Converters routinely handle “mega-rolls” and reduce them to “usable-size rolls” for packaging customers.
Custom Sheet Sizes: Suppose you need sheets of 48″×96″ for a die cutter, but standard off-the-shelf is 40″×60″. A converting partner can run the paper through a wide sheeter and a guillotine to produce your exact panel size. This avoids having to trim sheets by hand or waste excess. Custom sheeting is invaluable for unusual dimensions, specialty cartons, or when tight tolerances are required.
Detailed Labeling for Production: In fast-moving lines (like film coating or printing), knowing exactly which roll or sheet is loaded saves time. Converters can apply durable labels to each roll or bundle. For example, one converter’s practice is: “All slit rolls are labeled with product name, length of roll, PO #, Roll ID #, date of manufacturing”. That means every roll arriving at your dock comes clearly marked, eliminating guesswork for machine operators.
Tailored Bundling & Packaging: Consider a situation where 500 sheets of coated board need to be shipped safely. The converter can bundle them in layers with slip sheets, band them, and wrap the stack in plastic film according to your spec. For rolls, converters will build pallets “to customer and product specification with no material overhang,” applying strapping and shrink-wrap as needed. This customized pack-out ensures the material arrives undamaged and ready to use.

In each case, the converter works closely with the customer to understand the downstream process. Whether it’s adjusting roll widths, changing sheet formats, or adding scannable labels, custom converting solves problems that off-the-shelf products can’t.

Benefits of an Experienced Converting Partner

Working with a seasoned converter brings important advantages:

Industry Expertise. A converter with decades of experience has deep know-how. For example, Cauthorne Paper emphasizes that with “over a century in the paper converting business, we bring unmatched knowledge and craftsmanship to every project” cauthornepaper.com . This means fewer surprises on specs or material behavior. Veteran converters understand which paper stocks convert cleanly, how moisture content affects cuts, and what packaging each type needs.
Flexibility & Capacity. A good partner can handle everything from large production runs to one-time custom jobs. Cauthorne notes that “from large-scale runs to custom orders, our team adapts to meet your unique needs with precision and efficiency”. So whether you need 100 rolls on short notice or a precise batch of prototype sheets, a flexible converter will adjust machinery and schedules to deliver on time.
Inventory and Turnaround. Leading converters often maintain substantial inventories of popular papers and convert them quickly. This means you avoid weeks of wait time – the converter can ship standard materials from stock or run custom converting quickly rather than ordering new parent rolls.
Value-Added Service. Beyond cutting paper, a top converter is a problem-solving partner. As Cauthorne’s site states, their goal is to be a “value-added supplier” that even assists with R&D projects and sourcing raw materials. In practice, this might mean the converter helps you test a new paperboard grade, recommends a more cost-effective stock, or tweaks machine settings. They serve as consultants, leveraging their conversion expertise to improve your product and process.
Strong Supply Relationships. An established converter has long-standing relationships with paper mills. This often translates to better material availability and competitive pricing. It also means the converter knows alternative sources if a particular paper grade is back-ordered, helping prevent production delays.

In short, an experienced converting partner combines technical skill, flexible production, and customer service. This results in higher-quality output , more reliable delivery, and often lower total cost of ownership – you’re buying exactly what you need, with minimal waste or downtime.

Getting Started: Consult with the Experts

If your operation is struggling with unusual paper sizes or packaging requirements, it’s worth reaching out to a custom converter. Start by describing your needs – the paper grade, original roll size, and the final form or packaging you require. Many converters (like Cauthorne) offer consultative quoting: they’ll advise on the best converting approach. Often a quick call or form submission can yield a plan or sample to test.

Think of a custom converter as part of your supply chain engineering: they can make your process smoother by delivering ready-to-use paper. So, for oversized rolls, odd dimensions, special coatings, or any tricky request, don’t hesitate to ask . A knowledgeable converter will collaborate with you to tailor a solution, whether that means slitting to exact widths, adding precise labels, or packaging the bundles for your line.

Slitting and Rewinding 101: How Large Paper Rolls become Ready-to-Use Rolls and Sheets

Thu, 22 May 2025 17:51:57 GMT

Paper arrives from the mill in jumbo “parent” rolls – imagine an 8-foot-wide, one-ton spool of paper or linerboard. These giant rolls are too big for most printers or packaging machines. That’s where paper slitting and rewinding come in: specialized converting machines slice those parent rolls into narrower rolls that are easy to handle. In simple terms, a slitter rewinder unwinds a huge roll, cuts (slits) the web to the desired widths, then rewinds the strips onto new cores. This process is essential for converting large parent rolls of paper into more manageable sizes suitable for various applications.

Modern slitter-rewinders can handle a wide range of materials – not just paper. They process everything from kraft and linerboard (heavy packaging grades) to thin printing papers , even films and foils. For example, Cauthorne’s machines will happily slit thick brown kraft paper (used for bag-making or interleaving), sturdy linerboard, or lightweight coated print stock.

The key is versatility : by changing blades and settings, the same machine can tailor rolls of chipboard, tissue, waxed paper, and more. In fact, paper slitting machines are capable of processing various types of paper and flexible materials, including paperboard, film, foil, nonwovens, and laminates. This means whether you need narrow rolls of release liner for tape, long sheets of kraft for insulation, or standard print rolls, slitting/rewinding has you covered.

A slitter-rewinder machine processing a giant roll of paper. The unwound web will be cut by blades and rewound into smaller-diameter rolls.

The slitting & rewinding process works in three main steps:

Unwinding: A giant parent roll is mounted on the machine’s unwind shaft. Heavy-duty arms or powered shafts support the roll. The web (paper) is pulled off the roll at speed.
Slitting: As the web unwinds, it passes through a row of precise knives. These circular or razor blades slice the web along its length into narrower strips. For thin printing stocks, razor blades quickly and cleanly cut the paper. For heavier board or kraft, heavier-duty shear blades (like scissors) may be used. (Shear slitting uses top-and-bottom circular knives and is ideal for very thick or tough materials.) The number of knives (and cut widths) is fully adjustable.
Rewinding: After slitting, each cut strip of paper is immediately rewound onto a new core. Multiple rewind shafts (sometimes on a rotating turret) allow continuous operation: one roll winds while the next core is loaded. Tension controls and guide rollers keep the roll tight and even. When finished, you end up with many smaller rolls – each the exact width and diameter the customer needs.

Aside from slitting, these machines often include trim slitting and other finishing. Trim slitting cleans up the edges, and center perforation or embossing units can add features. Safety covers and sensors ensure operators stay protected. Today’s slitter-rewinders are often computerized, so an operator can dial in exact widths (even to 0.001″ tolerance), automatically align edges, and monitor tension.

The result of slitting and rewinding is a variety of customer-ready rolls. For example, a corrugated box maker might need 24-inch-wide rolls of linerboard from a 100-inch jumbo parent roll. The slitter-rewinder would slice that roll into four 24″ rolls (with a bit of trim) and rewind them to new cores. Each new roll can be any length or diameter; Cauthorne’s equipment lets us rewind to custom lengths or roll sizes. This custom slitting is a key part of our paper cutting services – it saves customers the cost and hassle of buying oversized material and then cutting it themselves.

Machinery: Slitter Rewinders and Sheeters

Slitter Rewinders:

These are the workhorses of roll conversion. A slitter rewinder looks like a row of shafts, rollers, and blade stations. In a two-shaft (turret) machine, one set of shafts unwinds a jumbo roll while two or more winding arms stand by. As each strip is cut, it automatically winds onto a fresh shaft.

Dual-drum or surface-winding configurations handle anything from tiny test rolls to massive production runs. For instance, duplex slitter rewinders can produce two smaller rolls at once.

Key features: adjustable tension control, computer knife positioning, and high-speed operation for maximum throughput.

Sheeters (Cutters/Trimmers):

After slitting to width, many customers need flat sheets of paper. A sheeter is essentially a rolling web that feeds into a rotating knife. It converts a roll into stacks of sheets. As one example, our in-plant Sheeter can cut sheets up to 55″ long from the web.

The process is: unwind the slit roll, run it under a cutter, and cut at fixed intervals. If exceptionally short sheets are needed, we use high-precision guillotine trimmers. In short, sheeting and trimming are paper cutting services that turn rolls into ready-to-print or ready-to-convert sheets.

Whether using a slitter or a sheeter, our goal is always precision. As one manufacturer notes, the slitter-rewinder’s flexibility “allows for the customization of paper rolls to meet specific size and width requirements,” yielding custom-sized rolls for printing, packaging, and more. In practice, that means a roll of kraft can become many rolls of groceries bag stock, or a newspaper stock roll can become dozens of newsprint reels, all cut to spec.

Why Do We Slit and Rewind?

Slitting and rewinding solve real manufacturing puzzles. Here are some practical examples and benefits:

Space & Shipping: It’s much more efficient to ship 30″-wide rolls than 150″-wide ones. Smaller rolls stack nicely on pallets and fit in customer machines. By slitting a parent roll into five smaller rolls, we reduce waste space and lower freight costs.
Equipment Compatibility: A map-printing press might only take 40″ rolls, but the mill ships 80″ rolls. Slitting “bridges the gap,” quickly resizing the material. Similarly, a bag-making machine might need 36″ kraft rolls instead of the 96″ mill jumbo. Slitting rewinding provides exactly that.
Quick Turnaround: Large distributors and converters rely on fast turnarounds. Using modern slitter rewinders, a one-ton roll can be processed in minutes. For example, one industry peer brought in a 10,000-pound linerboard roll on Monday, and by Tuesday had dozens of narrow rolls ready for their corrugator.
Waste Reduction: Precision slitting minimizes scrap. If a customer needs an odd width (say 23.37″), we cut it exactly and can use trimmings for smaller orders or sample packs. In fact, custom slitting can cut waste (and cost) by getting the right sizes in one step.
Versatility: One machine can handle kraft paper (brown, heavy-duty grades used for shopping bags and cartons), linerboard (paperboard used as corrugated facings), printing papers (newsprint, bond, coated, etc.), and more. We may use stiffer shear blades on heavy kraft/liner, or delicate razor blades for thin printing stocks. This versatility means our customers span many industries – from food packaging and industrial parts to publishing and textiles

Common Substrates

Kraft Paper: A strong, often unbleached paper used in bags, wrapping, and interleaving. Its thickness can vary (30–80 lb base). Slitting kraft typically uses slower speeds and stout blades. Kraft rolls might be rewound coreless (wound on the paper itself) or onto cores.
Linerboard: This is the flat paper used on top/bottom of corrugated board. It’s generally heavier (ranging up to 200 lb cover equivalent). Linerboard slitting is similar to cardboard sheeting – blades and pressure must handle its thickness without crushing.
Printing Papers: Newsprint, book paper, coated stock, etc., are thinner (20–100 lb range) and often fragile. Razor slitting is ideal here, and tension control is critical. We can rewind large spools of coated stock (e.g. magazine grade) that go straight into presses.
Tissue and Specialty Papers: While not all converting shops handle tissue, our slitter rewinders and sheeters can be set up (with webbing controls and perforators) to cut many types of tissue including napkin tissue and bath tissue.

Each material has its own rules, but the core idea is the same: start wide, end with customer-ready roll or sheet. Our team’s expertise (often guided by our in-house “Paper Doctor”) ensures the process is tuned for every substrate.

Slitting Methods

Razor Slitting: Uses sharp razor blades mounted on holders. Excellent for thin, non-abrasive materials like paper or lightweight film. Quick changeover, good edge quality.
Shear Slitting: Uses paired rotating circular knives (top/bottom like scissors). Ideal for heavy or abrasive materials (thick paperboard, metalized films, laminates). Produces very clean cuts on tough substrates.
Score Slitting: One blade against a hard roll surface. Used for difficult-to-cut films or adhesive laminates. (Usually not needed for standard paper slitting – we primarily use razor or shear.)

Each slitter-rewinder machine may be set up differently: some have fixed knives (steel rules), others have pneumatic or manual adjustment for quick blade changes.

Example: Converting a Jumbo Roll

Let’s walk through a quick example. Suppose a manufacturer receives a 91-inch-wide roll of kraft paper from the mill, weighing 3,000 pounds. They need 12″-wide rolls to feed into their bag machine, and about 500 feet long each. Here’s what happens:

Receive & Mount: The operator places the jumbo roll on the slitter machine. Safety checks are done.
Setup: The operator (or our technician) programs the slitter to cut 12″ widths and calibrates tension. Razor knives are positioned every 12″.
Process: The roll unwinds, and the knives slice the web into about 7 strips (since 91″ / 12″ ≈ 7.5, so we trim off the extra). Each strip winds onto a new core simultaneously.
Output: Within minutes, seven small rolls (12″ × 500′ each) come off the machine, plus a trim roll (which we save or recycle). The customer’s required roll size is now complete.

Later, if the customer also needs 24″×36″ sheets of that same kraft, we could use a similar roll and slit to 24 and take those ″ rolls to a sheeter. The sheeter would cut sheets to 36″ length, stacking them for delivery or further die-cutting.

Integration into Paper Cutting Services

At Cauthorne Paper, slitting and rewinding is part of our broader paper cutting services menu. We don’t just slit – we can also slit-to-width, sheet-to-length, and die-cut if needed. Many customers call us for “paper cutting services” when they need non-standard sizes or quick turnarounds. For example:

Packaging industry: needs custom wrap sheets or roll lamination stock. We slit 80″ rolls into 20″ rolls and sheet it for die-cutting.
Printer: orders 48″ rolls of glossy paper for a run, not wanting to buy an 80″ roll. We slit their glossy roll to 48″ and rewind.
Nonwoven/textile: even fiber manufacturers have used our services to convert specialty fibers on paper rolls.

We often describe our work as solving paper puzzles . Whether it’s producing the exact roll diameter a customer specified, or handling a delicate thermal paper stock without tearing, we adjust our process. In fact, Cauthorne’s slitting/rewinding services “are customized to the specific needs of our customers. We can slit a variety of materials to custom widths and rewind to custom lengths or roll sizes”– exactly the kind of flexibility today’s converters demand.
