Abstract
Abstract An article such as a tube formed of heat-shrinkable material is bonded exteriorly or interiorly to an elastomeric member to form a laminated article. The bonding preferably takes place before heating and expanding of the heat-shrinkable tube. After expansion and cooling, the parts remain in the heat recoverable position. Subsequent heating of the parts causes them to recover radially about a substrate.
