Strip of a plastic which can recover its shape under heat

摘要

A strip (1) of a plastic which can recover its shape under heat has on two mutually opposite longitudinal edges reinforcements, over which a rail (8) is pushed after the said strip has been laid around a substrate to be sheathed. The reinforcements are formed by a metal sheet (2, 3), which is formed over the longitudinal edges of the strip (1) and is shaped in the manner of a spiral (6, 7). <IMAGE>
