Heat-shrinkable cover sheet.

摘要

A heat-shrinkable cover sheet used for covering and protecting the peripheral surface of a joint of, for example, a steel pipe or cable is provided. The heat-shrinkable cover sheet has two branched tongue-like portions on each of both the ends in the direction of thermal shrinkage. A heating element formed of a heating electric conductor wire is included and built in the body portion of the cover sheet, the front tongue-like portion on one end of the cover sheet and the back tongue-like portion on the other end of the cover sheet, in a manner such that thermal shrinkage of the entire sheet is not prevented. The heating element included in at least one of the tongue-like portions having the heating element included and built therein is independent from the heating element of the body portion of the sheet, so that application of electricity to the independent heating element and stopping of application of electricity to the independent heating element can freely be carried out while electricity is applied to the heating element of the body portion.
