Abstract

1440682 Mixing viscous materials UNIROYAL AG 19 July 1973 [21 July 1972] 34379/73 Heading B5A [Also in Division B1] A single screw extruder comprises a screw conveyer 4 rotatably mounted in a housing 2, the screw conveyer having at least one flight of threads having spaces between adjacent lands of the screw, obstacle means 7 projecting into at least one of said spaces, and means for controlling the depth of projection of the obstacle means. In the embodiment of Fig. 1 the screws 7 are screw threaded for adjustment. In the embodiment of Fig. 3 the obstacles 7 are mounted on fixtures 10 which engage in a cam track or tracks 15. The cam track or tracks are on a gear-wheel 14 which can be driven from drive shaft 17 by gear 16. Thus the positioning of the obstacles can be automatically controlled.
