Abstract
A device for manufacturing electrical and/or optical cables which contain either one or more electrical and/or optical leads which are received with a filling compound in an outer casing or jacket characterized by an extruder for extruding the jacket, an arrangement for inserting each of the leads through a guide tube into the extruded outer casing and providing a second concentrically arranged tube for receiving and transferring the filling material for discharge around the guide tube into the extruded jacket. Preferably, the extruding device also includes an arrangement for stretching the tube to a reduced diameter with a conical-shaped zone or cone extending between the extruded casing and the stretched casing and the guide tube and the filling or second tube extend into this zone or cone.
