Abstract

1536542 Extrusion impelling FARREL BRIDGE Ltd 9 Jan 1976 [10 Jan 1975] 1037/75 Heading B5A An extruder screw 60 is rotatable in either of opposite directions to respectively deliver the material from an inlet 56, e.g. from a mixer 10, in one direction to the extrusion die, or in the opposite direction to an outlet 72, e.g. so that inhomegenous material fed from the mixer 10 to the inlet 56 at the commencement of feed, is fed through an operable door 74 of the outlet 72, e.g. to be returned to the inlet of the mixer 10.
