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.
