It is a quick coupling used in shafted center wind and center unwind applications. Safety Chucks do three things: They provide for quick change at the end of a production run (either winding or unwinding). A key benefit of the Safety Chuck is that it provides for less down time during turn around, making the
Centering shafts center the expanding shaft inside the core to eliminate roll loping and vibration issues related to roll bounce. By centering the shaft with-in the core, higher speeds are possible as well as a smoother pay-off that helps reduce waste in coating, laminating and printing operations. In addition, most operations running foils or webs
Differential winding is a clutching adjustment that allows tension to equalize from one slit roll to the next on the same shaft or rewind operation. Each individual rewind roll is completely isolated from all others. Some defects that can be addressed by winding products on a Differential Shaft include: Film caliper variation Coated products with
A reel spool is a large diameter mandrel used for winding and possibly storing large rolls of paper board and tissue. More and more mills are winding on cores (10″, 12″ 14″, 16″ on up) right on the tissue & paper board paper machines. Why? They do this to by-pass the paper machine winder. By
