JSI, has developed the first Automated Slitting System with Robotic blade changes. The evolution of old technologies provides many options and optimization not available in the past. With the additional of the robotic axis and returnable blade holders operators no longer have to be responsible for the maintenance and handling of slitter blades.
Accu-Slit by JSI is an innovative automatic slitter positioning system that sets in five seconds or less, making it the best choice when minimum positioning time and maximum positioning accuracy are required.
The system utilizes individual brushless linear servo motors on each slitter carriage. Carriages are positioned with linear motors that offer high speed, zero backlash, and maintenance–free, non-contact operation. The linear motor has zero internal moving parts, reducing the chance of breakage or malfunction. Carriage positions are tracked with non-contact magnetic encoders, eliminating the need for homing after a power loss because the absolute position encoders provide instantaneous feedback for each carriage, saving precious time and dollars. The non-contact feature of the components ensures no degradation in performance over time, in contrast to gear and belt-driven systems that wear out with heavy use.
Transfer rod positioning systems are the solution when simple and effective automatic slitter positioning is needed. This traditional slitter positioning system utilizes a single servo motor with linear transfer rods for top and bottom slitter carriages. These carriages then clamp onto the rods for movement and transfer to the fixed rails during slitter operation. An absolute encoder continually monitors the position of each slitter carriage.
The cost-effective manual slitter position (MSP) utilizes slide valve carriage brake control operation. This affordable solution can be upgraded to auto-positioning at a later date.
JSI offers custom-built slitter section upgrades and partial rebuilds to existing systems, including beam replacements, carriage rebuilds, and slitter unit upgrades to OEM systems.
JSI also provides custom-designed solutions to replace nearly any OEM component.
Pre-trim slitter units are structurally rigid, easy to set up, and effective on any PM or Converting application. Self-contained pre-trim units are a continuously-moving web with quick and easy width and depth adjustment. Pre-trim slitter units are equipped with our patent-pending Quick Cap design for quick, safe, and easy top knife changes and a bottom-driven anvil on a completely independent trim assembly. These ergonomically-designed, operator-friendly units are durable, safe, and can exceed 7,000 FPM.
Double trim slitter units are a safer and more effective way to eliminate butt rolls while reducing paper jams in the trim chute, resulting in a faster winder. Splitting the trim allows the continuous feed to cross-hatch into the trim chute system, minimizing the binding effects of wide trim. Double trim slitter units are equipped with our patent-pending Quick Cap design for quick, safe, and easy top knife changes, a cost-effective way to improve production times.
Trim removal systems provide customers with turnkey solutions for all material handling needs. There are 12 standard pre-fabricated options to remove trim scrap, paper waste, foil, laminates, cloth, carpet, and a number of other materials. Each are dependable, maintenance-free models that come in vertical, horizontal, and 45-degree arrangements, making them portable and self-contained to meet each plant’s needs.
JSI also can customize a material handling solution or build an automated material handling system based on a company’s need and budget.
The Quick Change Series Holder provides a safer and more efficient blade exchange process, a revolutionary approach to slitter section maintenance. The Quick Change Series Holder allows the user to exchange slitter blades in less than nine seconds without the use of tools. The blade is changed in seconds with the push of a button, guarding employee safety and ensuring a smoother production process.
This revolutionary design mechanically holds the blades in place and releases them when pneumatic pressure is applied, preserving the holder integrity if air pressure drops or is lost during operation of the slitter machine. This state-of-the-art design incorporates a custom-made pneumatic valve and bypass valve, preventing the slitter release feature from engaging while the slitter is engaged in position.
Existing machinery from Valmet, Metso, Wartsila, Beloits, Mario Cotta, Tildands and Beloit-Lenox can be retrofit with the Quick Change Series Holder by JSI.
The Accu-set Holder by JSI Holder has:
Ensuring optimal slitting performance is a combination of a number of factors:
If any factors are not functioning properly, it can result in a shortened slitter life and excessive downtime for slitter changes and return roll due to dusting and rough edges. Managing this process can be costly and time consuming.
The Slitter Solution Program (SSP) is a comprehensive solution configured specifically for your slitter section needs. The SSP will help your mill control the slitting process, extending blade life and band change intervals while improving roll quality. Implementing SSP by JSI will help decrease maintenance costs and increase efficiency.

Edlon has more than 40 years experience supplying roll release solutions to the papermaking and converting industry. It offers roll covers Teflon® and Roll-Coat™ coatings for dryer, bowed, carrying, lump-breaker and felt rolls. These heat-shrinkable covers and spray-applied coatings eliminate many of the traditional roll problems associated with paper production such as build-up, corrosion, and frequent downtime for cleaning and maintenance.
Edlon‘s roll covers and coatings offer a superior high-release surface that resists adherence by foreign substances and eliminates sticking, picking, and corrosion. With proprietary On-Machine Seaming technology (OMSTM), Edlon field service technicians can install a heat-shrinkable sleeve on a dryer without removing it from the paper machine. All covers are compatible with a variety of substrates including aluminum, brass, stainless steel, fiberglass, carbon steel and rubber.
Edlon roll covers and Roll-Coat coatings keep dryer rolls clean and smooth even after years of use. Because there is less fiber picking and build-up, there are fewer stops for cleanup and maintenance, enabling rolls to run longer, faster, and at higher temperatures. The end results are increased production efficiency, higher quality paper, and substantial savings in time and money

BTG headbox sheets improve the operations of the paper machine. The headbox nozzle is a critical area in developing high-quality paper parameters. Therefore, our unique manufacturing process produces sheets of highest quality.
We offer the smoothest polycarbonate surface in the industry through a special finishing process that provides an extremely smooth finished surface. In addition, we can apply a surface modifier to enhance the material’s release aspect -promoting even cleaner operating sheets.
The sheet tip is the primary controlling item in developing the nozzle flow characteristics. Sheets come in various tip designs including: “Blunt”, “Tapered” and “Serrated”.
Two different types of material are available: Polycarbonate and CPVC
BTG uses a unique and proprietary flow modeling technique we refer to as “Energy Expansion” calculations. This method allows us to easily review the effect that specific sheet designs have on the flow inside of the headbox nozzle while also being able to categorize the fiber activity levels present. In turn we can then engineer sheet designs to allow the headbox to operate in its ‘sweet spot’. So if you want to improve headbox sheet profile uniformity give a BTG expert a call and let us show you how!
