The CU Series—CU1500/CU1800 Winder is primarily used for high-speed winding of vellum, papers, and polyester reproductive films with a thickness range from.5 mil through 5 mils. The rear-mounted unwind assembly includes full lateral travel of headstock and tailstock to accommodate various roll widths and positions within the web area. The manually controlled, pneumatically actuated tailstock engages the quick lock chucking system to the master roll. The CU1500/CU1800 Winder web tension is controlled by a constant pressure that is supplied to the pneumatic unwind brakes, through an air regulator and pressure gauge. The intermediate web guide roller provides web support and wrinkle removal, preparing the web for the slitting station. The winder can be equipped with rotary shear-, score-, or razor-slitting stations. The CU1500/CU1800 Winder slitting station is designed for edge trims and one center cut. Knife bar mounted on quick release swing assembly is located near rewind mandrel with swing assembly control within the convenient working distance of the operator. The web is wound onto a fiber core over an air expanding rewind shaft. The simplex center rewind shafts are flange mounted to provide ease of change to other desired sizes.
The optional selvage eductor has a venturi vacuum pickup, which is powered by a 3 horsepower blower, transports edge trim through two 2″ diameter intake tubes mounted to the slitter bar by adjustable clamps.
