Abstract

976,006. Mixing by compression. J. J. G. DAUBENFELD. Nov. 21, 1962 [Nov. 25, 1961], No. 44044/62. Heading B1C. A plasticizing mill especially for polyvinyl chloride comprises a rotary drum and one or more rotary rolls therein parallel to but offset from the axis of the drum to provide a nip between the drum and the roll(s). As shown, the drum 1 is driven by a worm 5 and ring gear 4 and there are two rolls 2. A stripping knife 3 extends the length of the drum being pivoted on a shaft 6 ; it strips material from the drum wall and directs it into the nip between the rolls 2. The drum and/or the rolls may be plain or screw-threaded ; the threads may or may not intermesh. The rolls may rotate as shown in the same direction as the drum and as each other, or oppositely in either case, screw-threads when provided being handed accordingly. The speed of rotation of the drum and rolls may be independently infinitely variable and the gaps between the rolls, and between the rolls and the drum, may be adjustable. The drum and the rolls are both heated. The apparatus may discharge into a short screw press, Fig. la (not shown), the speed of which is co-ordinated with that of the apparatus.
