Abstract

1373155 Moulding plastic substances S FICKER 24 Feb 1972 8694/72 Heading B5A [Also in Divisions B1 and C3] In a continuous process for the regeneration of waste rubber or plastics, the material is crushed and fed to a mixer 6 when a metered quantity of mixed regeneration fluid and softener is added. After resting, the thus prepared material is metered to a heated multiple screw device 9 having one or two pairs of screws driven by a steplessly variable gear 17. The flights of adjacent screws overlap but are not in contact, each pair consisting of a single-start screw and a doule-start screw which rotates in the same direction, but at half the speed of the single-start screw, so that they are mutually self-cleaning. The clearance between flanks of adjacent screws, and between -the screws and casing, is preferably less than 4 m.m. Heat exchange fluid may be introduced both into the screws and into the casing. The material is preferably heated to 240-280‹ C. and is depolymerized in the device 9 for 5-25 mins., after which it may fall into a refiner 19, having water-cooled mills 20, 21, which produces a rough sheet 22.
