Abstract

Abstract Translated from German Die Erfindung betrifft ein längsgeteiltes Muffenrohr (1), welches ein Formgedächtnis aufweist und bei dem entlang der Trennungslinie an den Längsrändern des Muffenrohres (1) Hakenelemente (3, 6, 11-12) und Rastelemente (7, 13-14) angeordnet sind, die an Verstärkungen (2, 5, 8) befestigt sind. Auf diese Weise werden während des Schrumpfvorganges die erweichenden Längsränder gefestigt und die wirkenden Schrumpfkräfte von den Längsrändern des Verschlußsystems abgehalten. Dabei erfolgt die Aufnahme der Schrumpfkräfte durch die Haken- (3, 6, 11-12) und Rastelemente (7, 13-14), während die Abdichtung in diesem Bereich durch einen geeigneten Schmelzkleber erfolgt. The invention relates to a longitudinally divided sleeve pipe (1) which has a shape memory and in which hook elements (3, 6, 11-12) and latching elements (7, 13-14) are arranged along the dividing line on the longitudinal edges of the sleeve pipe (1), which are attached to reinforcements (2, 5, 8). In this way, the softening longitudinal edges are strengthened during the shrinking process and the effective shrinking forces are prevented from the longitudinal edges of the closure system. The shrinking forces are absorbed by the hook (3, 6, 11-12) and locking elements (7, 13-14), while the sealing in this area is carried out by a suitable hot melt adhesive.
