PRIMASLITTM RL Duplex Slitter Rewinder - Rear Loading

The PRIMASLITTM RL (Rear Loading) Duplex Slitter Rewinder offers twin benefits of high output and compact size by accommodating the unwind and duplex rewind sections on either sides of a common frame to convert larger diameter reels (intended for onward conversion into lamitube or pouches) at speeds upto 600 m/min.

Two side operation with integrated unwind on the rear side
Pneumatic swivel arm off loader
Advanced material handling options
Speeds upto 600 m/min
