Slitting Systems

Accu-Slit L (Linear)

Accu-Slit L 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 money.

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.

  • Speed: All slitting positions set-up under 5 seconds!
  • Linear Motors: Located at all positions, moving all positions simultaneously.
  • Accuracy: Highest accuracy in the industry with +/-.005” at all positions.
  • Technology: Uses JSI Accu-set Holder for easy, SET IT and FORGET IT, blade set-up.
  • Low Maintenance: Extended service life due to no moving screws or belts.
  • Sealed: Pressurized chamber keeps all components free of dust and debris.
Accu-Slit R (Rod)

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.

  • Fast: Rod-style servo motion, moving up to 4 positions at one time. Most set-ups achieved in under 1 minute.
  • Accurate: Absolute magnetic encoders at each position +/-.015” accuracy.
  • Controls System: Industry leading Rockwell Automation control system.
  • Technology: Uses JSI Accu-set Holder for easy, SET IT and FORGET IT, blade set-up.
  • Easy: Upgrade to existing systems.
  • Cost Effective: Lowest cost option to upgrade to Auto-positioning.
Accu-Slit B (Belt)

The most cost-effective Belt System in the industry.

  • Never have an operator touch a slitter blade.
  • Reduce downtime due to blade changes.
  • Gain accuracy predicting blade wear.
  • Maximize blade life through wear traceability.
  • Minimize damaged product due to dull blades.
JSI Automated Slitting System with Robotic Blade Changes

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 addition of the robotic axis and returnable blade holders, operators no longer have to be responsible for the maintenance and handling of slitter blades.

  • Never have an operator touch a slitter blade
  • Reduce downtime due to blade changes
  • Gain accuracy predicting blade wear
  • Maximize blade life through wear traceability
  • Minimize damaged product due to dull blades

Trim Systems

Pre-Trim Slitter Units

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 – Butt Roll Eliminator

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 crosshatch 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 System

Trim removal systems provide customers with turnkey solutions for all material handling needs. There are 12 standard prefabricated options to remove trim scrap, paper waste, foil, laminates, cloth, carpet, and several 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 can also customize a material handling solution or build an automated material handling system based on a company’s need and budget.

Knife Holders by JSI

Accu-set Holders by JSI

Accu-Set Series I- Direct replacement for OEM Knife Holders

Read it:
JSI service centers will circle the diameter of the blade after sharpening.

Set it:
At installation, operator reads circled diameter and sets the Accu-Set depth dial to the corresponding value.

Forget it:
The holder is set to the correct depth for the bottom band location the FIRST TIME, EVERY TIME!

Safety features & Benefits:
  • Reduces operator contact with a shape blade
  • Safe and fast tool-free slitter blade removal
  • Easy operator training for quick set-up
  • Increased productivity and reduced down-time
Quick Change Holder by JSI

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 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.

  • Greatly reduces the operator’s contact, reducing risk of injury
  • No tools required to change the blade
  • One-step blade removal process
  • Change the blade in less than nine seconds
  • Blades removed only under pressure
  • Decreased maintenance costs and increased reliability
  • Increased depth adjustments for extended blade life
  • Enclosed and sealed cartridge design eliminates dust buildup
  • Available immediately for stock

*Existing machinery from Valmet, Metso, Wartsila, Beloits, Mario Cotta, Tildands and Beloit-Lenox can be retrofitted with the Quick Change Series Holder by JSI.
