Paper Core Cutter TWIN 3–2000 (TWIN 3-3000)

The machine cuts in progressive, single index action tubes from cardboard and soft plastics materials.

The tube is fed into the machine.
The required cutting lengths are programmed-in and the machine started.
Tube advance is actioned by servo-motor according to the programmed length.
First a trim cut is made and discharged then the complete core is divided into the corresponding length.
The first and last trim cuts are ejected to the rear of the machine separate from the cut sections.
