ABSTRACT:
Thin plastic tubes are prepared by extruding a heat plastified tube, stretching the tube over a gas bearing having a diameter greater than the diameter of the extruded tube, cooling the surface of the tube adjacent the gas bearing and passing the tube over a cooling mandrel having an outside diameter approximating the diameter of the gas bearing, thereby lowering the temperature of the tube below its heat plastifying temperature.
