Patent ID: 7261253

Claim:
A rewind arm assembly primarily for a slitter rewinder machine having a base supporting two or more rewind arms in spaced relationship, a rewind core rotationally supported between two adjacent rewind arms, each arm having a core driving shaft for coupling with a core engaging and locking chuck, the shaft being carried by spaced bearing assemblies located in a housing at the top of each rewind arm, the rewind arms being supported on said base for traversing and adjustment of the spacing between adjacent arms to accommodate differing rewind core widths, the machine further including a pressure contact roller positioned in parallel, surface to surface, contact with the core and mounted on arms which pivot so as to accommodate the increasing core diameter as the core is wound during use, wherein one side of the top housing of the rewind arm has the core shaft and support bearings adapted to the loads imposed by a first size of core internal diameter and the other side of the top of the rewind arm has the core shaft, and support bearings adapted to the loads imposed by a second size of core internal diameter.
