Abstract

1,138,362. Extrusion/calendering machines. DUNLOP CO. Ltd. 1 April, 1966 [15 April, 1965], No. 16146/65. Heading B5A. A machine for producing sheets of plastics material or of natural or synthetic rubber comprises in combination, an extruder 10, having ports 15 in a barrel 12 connected to a suction pump 18, and a roller assembly 11 which is driven to pull the extrudate from the extruder and comprises a driven roller 21 and a vertically adjustable roller 22. A screw impeller 19 is designed to apply a relatively high pressure to the material just upstream of each port 15 and a relatively low pressure immediately downstream thereof to facilitate the removal of volatile gases and moisture by the applied suction. Rubber extrudate may be led to a vulcanization plant. To facilitate maintenance, roller assembly 11 is mounted on a frame 26 movable along a slideway 27.
