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
