Abstract

773,542. Covering electrical conductors &c. by extrusion. CHEMISCHE WERKE HULS AKT.-GES. July 2, 1954 [Oct. 8, 1953], No. 19418/54. Class 87(2). [Also in Group XXXVI] Elongated structures such as tubes, wires and cables, either bare or with a coating, are covered with a thermoplastic material which has been cooled to the " frozen " state and then stretched transversely and longitudinally and applied to the object. The covering may eventually be shrunk on to the wire &c. by heating. The material may be polyvinylidene-chloride, polyvinyl chloride, polystyrene and their copolymers. As shown, a vinylidene chloridevinyl chloride co-polymer is extruded as a tube through the annular orifice 1, of 27 mm. diameter and gap width 0À1 mm., of an extrusion head 7 into cooling means 8 and over a mandrel 2 having an enlargement 4 of 27 mm. diameter. The drawing-off speed is adjusted so that the thermoplastic tube above the enlargement is 9 mm. diameter, to give a 3 : 1 transverse stretch. Cable 3 is supplied from spool 11 through an orifice in mandrel 2 and into the tube 6, the resultant encased cable being led over a drawn-off device 5 co-operating with profiled rollers 9, 10 which press the tube 6 against enlargement 4 and so control the longitudinal stretch of the tube as it is withdrawn from the mandrel, preferably by a similar 3 : 1 ratio. The encased cable 12 is then guided through a heating means 13 to shrink the plastic covering on to the cable. The air between the cable and the tube may be sucked out.
