Abstract

L'invention concerne la mise en place de fils électriques et l'enroulement d'une bande autour des extrémités d'un câble à paires torsadées et le déchargement du câble à paires torsadées complet sans temps d'attente et tout en économisant l'espace impliqué dans les opérations. À cet effet, un appareil de fabrication de câble à paires torsadées 1 est adopté, celui-ci comportant un premier élément rotatif intermittent 4 possédant des pinces 3 pour fixer les premières extrémités 2a des paires de fils électriques 2 sur chacune de trois surfaces circonférentielles 7 à 9, un deuxième élément rotatif intermittent 13 possédant des pinces 5 pour fixer les autres extrémités 2b des paires de fils électriques 2 et un moteur 6 pour faire tourner les pinces dans une direction circonférentielle sur chacune de trois surfaces circonférentielles, et une unité d'entraînement pour faire tourner par intermittence les premier et deuxième éléments rotatifs intermittents sur un tiers d'un tour complet à la fois, les trois surfaces constituant un plan de mise en place de paires de fils électriques 7, 10, un plan de torsion de paires de fils électriques 8, 11 et un plan d'enroulement et de torsion de bande de câble à paires torsadées 9, 12.
