Abstract

720,743. Extrusion machines. STINNES VERWALTUNG GES:, H. Feb. 18; 1953 [Feb. 23, 1952], No. 4581/53. Class 87 (2) In an extrusion machine for feeding two different materials to the nozzle, which incor-. porates two concentric and coaxial worms 1 and 2 with outer threads 5 and 7 working in jackets 3 and 4 respectively, the outer worm 1 is also provided with an inner thread 6 working against the outside of the inner jacket 4 which, through apertures 10 in the outer worm, feeds material from hopper 9 to the nozzle and so prevents jamming of material in the space between outer worm 1 and inner jacket 4.
