Abstract

Prezenta inventie se refera la un procedeu si la un dispozitiv pentru producerea dintr-o bucata, în special a unor mufe la tuburi, fabricate dupa procedeul rularii (înfasurarii) din banda profilata din material termoplastic. Procedeul este caracterizat prin aceea ca mufele sunt executate prin trecerea de-a lungul unui sector care se largeste conic la un diametru de rulare (înfasurare) mai mare, mufa fiind executata prin continuarea la început a înfasurarii pe diametrul de rulare marit si trecere adiacenta de-a lungul unui sector care se îngusteaza conic, înapoi la diametrul de rulare initial. The present invention relates to a process and to a device for the production of one piece, in particular of tubular sleeves, manufactured after the rolling process of the profiled strip of thermoplastic material. The process is characterized in that the sockets are executed by passing along a sector which conically widens to a larger tread diameter, the socket being executed by continuing at the beginning of the fitting on the increased tread diameter and the adjacent passage along a sector that narrows conically, back to the initial running diameter.
