ABSTRACT A strip of hollow heat-recoverable articles formed side-by- side by tear welding two lengths of polymeric material together at intervals so that individual articles may be torn off. A preferred method of making the strip involves cross-linking after the teas welding, heating the strip, and inflating the hollow articles to render them heat-recoverable by introducing pressure via an interconnecting passage formed for that purpose during the tear welding.
