Zusammenfassung: | The procedure for winding a composition glass and plasticbased tape (2) onto a body (3) such as hollow extruded plastic pipe using a feed and laying system (4) with at least one rotating roller (41) stops the roller from rotating while the feed and laying system performs a continuous translation movement, and frees it to rotate while it is changing direction or pivoting. The roller can be stopped by a friction brake, by the interaction of male and female components, one of which forms part of the roller, or by a digitally-controlled pneumatic system. At the output from the feeder the tape is maintained at a temperature equivalent at least to the melting point of the tape's plastic material, and the tape can be bonded to the body with the aid of a pressure roller (14) and a heater (15).
Procédé d'enroulement d'un ruban composite (2) à base de verre et de matière plastique autour d'un corps (3) au moyen d'un système de délivrance et de dépose (4) qui comporte au moins un galet tournant (41), le procédé consistant en ce que le système de délivrance et de dépose (4) du ruban effectue des mouvements de translation et/ou de pivotement, caractérisé en ce que le galet tournant (41) est mis en arrêt de rotation lorsque le système de délivrance et de dépose (4) effectue en continue un mouvement de translation, tandis qu'il est libéré en rotation durant le changement de direction et/ou de pivotement du système de délivrance et de dépose (4). |
