Abstract

992,310. Extrusion machines. LILON ESTABLISHMENT. March 25, 1964 [March 29, 1963], No. 12672/64. Heading B5A. Apparatus for plastifying and extruding thermoplastic material comprises a screw 20 for plastifying the material and feeding it to a metering pump 22 which passes it to an extrusion die (not shown), and the screw spindle 6 is axially displaceable in response to the pressure of material in the space 23 between the spindle and the pump 22, whereby a piston-like enlargement 18 on the piston controls the flow of material through the apparatus by regulating the admission into a recess 28 in the wall of the housing 1, through which recess 28 the material is fed to the screw 20. The degree regulation may be controlled by the setting of a pivoted flap 34 in the recess 28. The raw material is fed in granular form through a hopper 25 and is stirred by vanes 27 on the spindle 6.
