Abstract

936,014. Pugmilis. ONDERZOEKINGSINSTITUUT RESEARCH N.V. June 21, 1961 [June 22, 1960], No. 22418/61. Class 86. [Also in Group V] A minor proportion by weight of a solid substance 13, e.g. pigment, is mixed in a screwextruder with a thermoplastic material 11, the substance 13 and the thermoplastic 11 being fed separately and in a divided state to the extruder and the minor proportion being fed to the conveyer screw 4 at an inlet 5 having its centre upstream of the centre of an inlet 10 through which the thermoplastic material 11 is fed to the screw 4. The substance 13 is fed in known proportion to a tube 12 contained in a feed hopper 3 for thermoplastic material 11 and adjustably located near the wall of the hopper 3 remote from the extruder delivery end 7. The bevelled lower end 14 of the tube 12 frees the neighbouring wall of the hopper 3 so that the said end 14 and the wall diverge towards the screw 4. The tube 12 may be flexible with its end 14 extending between the threads of the screw 4. In examples given, the thermoplastic material 11 may be granular, polymerized polyaminocaproic acid and the solid substance 13 may be graphite, carbon black, molybdenum sulphide or amorphous silicic acid.
