ULTRASLIT® OHP Duplex Slitter Rewinder – Over Head Path

The ULTRASLIT® OHP (Over Head Path) Duplex Slitter Rewinder offers the best layout for a hygienic work environment, especially indicated for pharmaceutical and food industries. The overhead path also offers an easier web passage, better all-round access and good visibility of key areas of the machine while it runs at its rated speed of 700 m/min.

Floor lifting unwind separated by a bridge
Hygienic work environment due to overhead path
Excellent visibility and access to the cutting section
Pneumatic swivel arm off loader
Highly versatile & productive
Speeds upto 700 m/min
