Abstract
1340958 Screw mixers UNIROYAL AG 22 June 1971 [30 June 1970] 29192/71 Heading B1C [Also in Division B5] A screw for a single screw rubber mixer and extruder has a continuous thread 2 and between the turns thereof at least one partial thread 6, 7 of the same hand. The partial thread(s) and the unthreaded groove portions may consist of detachable arcuate plates 14, 15, 18 subtending an angle of e.g. 60 at the screw axis, so that various partial – thread arrangements may be tried to obtain optimum mixing. The partial thread(s) may have more or less than one full turn, may be of different pitch from the main thread, and may have tips 11 bevelled or chamfered. The screw may have a bore (13, Fig. 5, not shown) for a heat exchange medium.
