Title (EN) METHOD OF WELDING PLASTICS
(FR) PROCÉDÉ PERMETTANT DE SOUDER DU PLASTIQUE
Abstract:
(EN) Method for producing a peelable weld between plastic elements, in which the elements are pressed against each other and heated at the weld, and in which the elements comprise a layer of non-weldable material covering, at the moment when the elements are pressed together, only part of the weld area.
(FR) La présente invention concerne un procédé permettant de produire une soudure décollable entre des éléments. Lesdits éléments sont pressés les uns contre les autres et chauffés à la soudure, et ils contiennent également une couche de matériau non soudable recouvrant, au moment où les éléments sont pressés les uns contre les autres, seulement la partie de la zone soudée.
