Abstract
1,053,728. Pug mills. GEWERKSCHAFT SCHALKER EISENHUTTE. June 10, 1965 [June 13, 1964], No. 24529/65. Heading B1C. A pug-mill for synthetic theromplastics comprising a rotatable central shaft 4 surrounded by helically toothed members 6 meshing with teeth on the shaft and on the inner surface of the jacket and carrying an extrusion screw 4, has a rotary distributor upstream of the toothed members and below the feed hopper. The distributor may be a screw as shown, or comprise helical blades (Fig. 3. not shown). It may be secured to the central shaft 4, or as shown be coaxial with it and separately rotated. Alternating it may be a screw disposed coaxially in the feed hopper 3 and extending into the discharge shoot below it, Fig. 5 (not shown).
