Polyimide Rewind Slitting 1


Slitting involves cutting large log rolls of adhesive tape to a specified width. CGS has the custom tape slitting capabilities to convert various flexible materials and pressure sensitive adhesive tape to a customized width.

We use different styles of slitting machines, all of which are equipped with computer-controlled servomotors, allowing us to be able to make the most efficient use of materials. Thus, we can maintain a high standard of quality and provide the best solution for our customers.


Lathe slitting, also referred to as baloney or single-knife slitting, features quick cuts and  fast set up. To begin with, master rolls are clamped and spun on a horizontal axle, then a spinning circular blade cuts the material to the desired width. We have the flexibility to cut a wide variety of materials, including plastic films and adhesive tapes, because of our state of the art machines.



  • Width range from 0.03″ up to 50″.
  • Tolerances of up to +/- 0.003″, depending on the material.

Rewind slitting is more efficient because it can produce multiple cut rolls from a master log in one cycle. First, the machine unwinds the master roll, then it is fed through a series of blades. Next, the winds each section onto a new core, creating a new slit roll. CGS utilizes common styles such as score, shear and razor.

  • Score style cuts material by pressing a set of circular blades against a metal mandrel, after which, the material is pulled through the blade. Score slitting is more appropriate for materials of inconsistent thickness.
  • Shear style also uses a set of circular blades. The material is slit at the the junction of the two blades. It is ideal for paper, foil, and heavier gauge materials.
  • Razor style uses a set of stationary blades positioned across the machine. The machine pulls the material through the blades, while cutting it in the process. Razor style is best suited for films and thinner materials of consistent thickness.




  • Width range from 0.25″ up to 50″.
  • Tolerances of up to +/- 0.003″, depending on the material.
