Abstract

967,564. Automatic extrusion pressure control. IDDON BROS Ltd. May 24, 1963 [June 1, 1962], No. 21133/62. Heading G3R. To maintain extrusion head pressure at a desired value the feed screw A of a machine extruding rubber or plastic supplied at a is driven by a motor M through a slipping clutch C and reduction gearing C<SP>1</SP>. Variations in pressure in the die head (not shown) vary the thrust transmitted from the screw, through a bearing A<SP>1</SP> to a hydraulic piston B<SP>1</SP>. The resulting variations in hydraulic pressure behind piston B<SP>1</SP> operate a potentiometer D to control the excitation and thus the slip of clutch C so that die head pressure is restored to the desired value. A tachometer C<SP>2</SP> may be driven from layshaft C.
