STRIP OF THERMAL RECOVERING ARTICLE AND ITS MANUFACTURE |
摘要 |
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 tear 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. |
