WARMSCHRUMPFBARE GEGENSTAENDE.

摘要

A process for the production of a marker sleeve assembly which comprises deforming a substantially non-crosslinked web of polymeric material at a temperature below the crystalline melting point or softening point of the material to render the web heat-recoverable, fusing together parts of the web or parts of the web and at least one other polymeric web to define a plurality of radially inwardly heat-recoverable marker sleeves, disposed in side-by-side relationship and preferably separable and subsequently cross-linking the resulting assembly.
