Abstract

971,021. Corrugating plastic tubes. W. HEGLER. March 6, 1961 [March 5, 1960; Aug. 1, 1960], No. 8154/61. Heading B5A. A transversely grooved plastic tube 29 is moulded by guiding an extruded tube whilst still soft over a mandrel 21 and sucking the tube into grooved chill mould parts 4, 5 mounted on endless chains driven by wheels 2, 3, the speed of the moulds being half that of the plastic tube, to ensure keeping the wall thickness of the tube constant. When set, the grooved tube 29 is released from the mould walls by compressed air, while the mould parts are opened by means of a wedge 14 and move round the wheels 2a, 3a. The grooved tube 29 is then compressed by heating it and passing it through a chamber 42 which has air drawn off through ports 47 and 53, to cause the tube to undergo a slight braking; cold water is circulated through passages 49 to cool the plastic.
