Abstract

865,933. Mixing appliances. FARBENFABRIKEN BAYER A.G. Aug. 19, 1959 [Aug. 23, 1958], No. 28378/59. Class 86 A mixing and kneading machine especially for plastic materials comprises a mixing chamber 1 having a hopper 3 and two shafts 2 rotating in the same direction. The mixing members are differently formed in sections along the shaft, one section comprising twisting conveying: screws 4 and another a succession of contacting discs 5 mounted eccentrically on the shafts in such a manner that their centres lie on a helix as described in Specification 687,021. There may be additional worm and disc sections. A portion of the mixing chamber may be made gas-tight and used for de-gassing under reduced or atmospheric pressure, (see Fig. 3, not shown). The machine may have an extension nozzle 12, (see Fig. 4, not shown).
