fully automatic web rewinders

A fully automatic rewinder with an adjustable acceleration characteristic, controls a surface driven pneumatically braked unwind roller, providing the ability for rapid change of the mother roll. A four-position rewind system and lay-on/spreader roller, combined with an adjustable clutch gives precise control for low tensionless conditions, providing a perfect rewind profile. The finished roll length is accurately measured by an electronic counter using a preset control for slow down, while a consistent operation is maintained by an easy access hopper with automatically fed output conveyer.
