CARRIERLESS MEMBRANE PRODUCTION

Film Unwind

FILM UNWIND

The first component in the Carrierless Membrane Manufacturing Line is the Film Unwind Unit. This unit feeds rolls of polyethylene film or siliconized paper and bottom side selvage edge film onto the cooling belt for coating.

Roll tension is controlled by an electric brake system, and a film tracking unit ensures proper film placement and alignment.  

Bowed rolls assure optimum delivery of each film onto the cooling belt. These bowed rolls consist of a special rubber shell, with rigid axle and maintenance-free precision roller bearings.

Multi-layer membrane constructions utilize additional unwind units in addition to splicing automation.
