PRIMASLITTM FL Duplex Slitter Rewinder - Front Loading

The PRIMASLITTM FL (Front Loading) Duplex Slitter Rewinder offers a compact solution to the converting industry by having both sections on the same (front) side, thus making the area for reel loading and unloading common. As compared to conventional two side machines, this design offers greater convenience in web threading and limits the need for operator movement, allowing him to monitor the entire process from the front of the machine.

Unwind and rewind on the same (front) side
Minimum need for operator movement
Easy access to the cutting section
Pneumatic swivel arm off loader
Minimalistic design requiring minimum floor space
Speeds upto 600 m/min
