    • 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.
    • 用于卷绕压敏胶带的管状或环形芯具有纸板主体和由其外表面上具有剥离涂层的聚合物膜条形成的剥离涂层的最外层,并且在其内表面上具有粘性粘合剂层。 条带缠绕在芯上,带的一个边缘向外折叠离开芯,以便在折叠边缘上露出粘性粘合剂层。 该折叠边缘与带的相对边缘重叠,从而将粘合剂层彼此接触地放置在两个边缘上。 通过粘合剂 - 粘合剂接触实现重叠边缘之间的牢固粘合。 在优选实施例中,带的重叠边缘稍微超过折叠边缘重叠到条的未折叠的外表面上。 处理该展开部分以促进其重叠边缘的粘附。 在优选的实施方案中,通过将带材推进到芯体并将加压的张力施加到加热的带材上,从而实现将带材与芯体的改进的粘合以及条带与芯部表面中的不规则性的一致性改进 它被缠绕在核心上时伸展。
