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.
Claims19
A method of sealing an end of a sleeved roller comprising the steps of:
- a. providing a sleeved roller comprising (i) a roller-shaped body having a peripheral outer surace and an end defining a beveled outer edge continuous and unitary with said surface, and (ii) a substantially tubular lamina coaxially disposed about said body having a heat-shrinkable end of thermoplastic material extending substantially beyond said body end;
- b. applying a mass of synthetic elastomeric sealant over said body edge and between said lamina end and said body end;
- and
- c. heat-shrinking said lamina end to compress said lamina end about said sealant and said body to imbed said lamina end in said sealant mass and to bondingly engage said sealant to said lamina end and said body end, thereby sealing said body end.
