Slitting

Slitting is the process of cutting material in a straight line in the direction of the web (roll of material).  Slitting cuts the material completely as opposed to scoring in which cuts through selective layers of the material.  There are four main types of slitting which CRC uses:

• Crush cutting blades pinch the material between the blunt tip of the round blade and a hardened cylindrical anvil.  The blades can be adjusted easily to make the slit widths flexible.  This technique is ideal for foams and felts as well as some plastic and various film materials.  Because it crushes material, it is less effective with paper which tend to make dust and leave rough edges.   Our current capacity is 18" wide with 1.50" minimum slit width.
  
• Razor cuts use industrial razors to slice through material.  This is ideal for many thin films and leaves a very clean edge on most materials.   Our current capacity is 18 inches wide with 2.0 inch minimum slit width.
  
• Shear slitting involves two smooth rotating blades which act together to make a scissors cutting action ideal for paper and films that tend to stretch.  Our current capacity is 18 inches with a 1.50 inch minimum slit width.
  
• Rotary die slitting involves a regular rotary die with slitting blades.  This is very accurate and permits slitting to almost any width from .050 inches to the width of the die.
