Abstract
L'invention concerne un procédé de fabrication d'un câble électrique pourvu d'un dispositif d'allégement des forces de traction dans lequel des organes à résistance élevée et continus, se présentant par exemple sous forme de fils ou de retors sont disposés à intervalles et concentriquement à l'âme du câble dans l'enveloppe encore visqueuse du câble de manière que chaque organe d'allégement des forces de traction soit enrobé dans le matériau constituant l'enveloppe et pourvu d'ondulations à la sortie de l'extrudeuse. Lesdites ondulations sont provoquées par un procédé d'injection sous pression synchronisé et différencié sous le rapport des vitesses des divers eléments constitutifs du câble, en particulier dans la zone de la matrice extérieure de l'extrudeuse.The invention relates to a method of manufacturing an electric cable provided with a device for relieving tensile forces in which high-strength and continuous members, for example in the form of threads or twists are arranged at intervals. and concentrically with the core of the cable in the still viscous envelope of the cable so that each member for relieving the tensile forces is embedded in the material constituting the envelope and provided with corrugations at the outlet of the extruder. Said corrugations are caused by a synchronized injection process under pressure and differentiated with respect to the speeds of the various constituent elements of the cable, in particular in the zone of the outer die of the extruder.
