Abstract:

A tubular or ring-shaped core for winding pressure-sensitive tape has a paper board body and a release-coated outermost ply formed of a strip of polymer film having a release coating on its outer surface and a tacky adhesive layer on its inner surface. The strip is wound onto the core with one edge of the strip folded outwardly away from the core so as to expose the tacky adhesive layer on the folded edge. This folded edge is overlapped by the opposite edge of the strip, thereby placing the tacky adhesive layers on the two edges in contact with each other. A firm bond between the overlapping edges is achieved by the adhesive-to-adhesive contact. In a preferred embodiment, the overlapping edge of the strip overlaps slightly beyond the folded edge onto the unfolded outer surface of the strip. This unfolded portion is treated to promote adhesion of the overlapping edge thereto. Improved bonding of the polymer strip to the core, and improved conformance of the strip to irregularities in the core surface, are achieved in a preferred embodiment by heating the strip as it is being advanced to the core and applying tension to the heated strip to cause it to stretch as it is wound onto the core.
