SLITTING SYSTEMS

“The biggest improvement with the Accu-Slit System is the consistent roll width. 

The slit edge quality on our rolls have seen a significant improvement as well."

Accu-Slit L (Linear)

AUTOMATIC SLITTER POSITIONING SYSTEM

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.

Ditch your outdated slitter system. The Accu-Slit L provides:
  • Speed: All slitting positions are set up in under 5 seconds, dramatically reducing set up time.

  • 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 L system which uses individual brushless linear servo motors on each slitter carriage

Under the Hood

The Accu-Slit L 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.

Accu-Slit R (Rod) traditional slitter positioning system

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.

It’s time to move on from your old slitter system. The Accu-Slit R provides:
  • 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. Don't buy new, when you can upgrade your system with dramatic results.

  • Cost Effective: Lowest cost option to upgrade to Auto-positioning.

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 optimizations 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.

Benefits of using the JSI Automated Slitting System with Robotic Blade Changes:
  • Safe & Clean: Never have an operator touch a slitter blade

  • Fast: Reduce downtime due to blade changes

  • Accurate: Gain accuracy in predicting blade wear

  • Cost Effective: Maximize blade life through wear traceability

  • Improves Quality: Minimize damaged product due to dull blades

Never Worry About Changing Your Slitter Blades Again.

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.

Quick Change Series Holder is a JSI solution that allows the user to exchange slitter blades fast without using tools

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.

Reduce Injury, Replace Blades in Less Than 9 Seconds, and Decrease Maintenance Costs:

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 the 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.

KNIFE HOLDERS

“Training a winder operator on slitter set-up has been almost a ‘non-event.’ What used to take months to train on depth setting, side load pressure, and more has been removed because it is set up the same way every time. In addition, we have seen cost savings in blade regrinds from the previous year.”

Double Trim Slitter Units

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.
