Automatic Score & Shear Knife Positioners

Automatic Score Knife Positioning

Catbridge Machinery’s automatic score knife positioning system provides fast, accurate, repeatable slitting. This system can place up to 120 knives and allow slit widths as narrow as 1/2″. New features minimize mechanical errors and position score knives with an accuracy of +/-0.015”. Well-planned integration of the positioning system to minimize slit web length further enhances finished roll quality. A storage compartment houses blades for numerous cuts and slit patterns. Patented in US and Europe.

Automatic Shear Knife Positioning

Catbridge Machinery’s automatic shear knife positioning system provides fast, accurate, repeatable slitting. This PLC-controlled, servo-driven system yields extremely precise cut widths. The time to set knives depends on the web width and the total number of knives. For example, positioning 20 female knives over a 72” web takes less than 2 minutes. Depending on the blades used, the minimum slit width can be as narrow as 1”. Patented in US and Europe.
