ABSTRACT:
A method is provided for sealing the end of a sleeved roll comprising a roll-shaped body and a tubular sleeve-shaped lamina formed of a thermoplastic synthetic resinous release material coaxially disposed about the body, the lamina having a heat-shrinkable end extending substantially beyond the body. A synthetic elastomeric sealant is applied between the lamina end and the body end, and the lamina end is then heat-shrunk to compress the lamina end about the sealant and the body end and to bondingly engage the sealant to the lamina end and the body end, thereby sealing the body end. Preferably the body has a bevel on its outer edge and the sealant is applied over both the body end and the bevel prior to heat shrinking.
