Abstract

1,041,479. Multiple screw extension machines. O. FAHR. Nov. 27, 1964 [Nov. 27, 1963], No. 48233/64. Heading B5A. [Also in Division B1] A screw machine for mixing, kneading, degassing and extruding thermoplastics has intermeshing screw components a to e removably mounted as by splines on drive shafts 4, 4<SP>1</SP> divided into two parts at X in the neighbourhood of the feed hopper 1. The shaft portions are held together by tie-bolts 6, 6<SP>1</SP> and externally accessible nuts 7, 7<SP>1</SP> which when released enable the major portions of the shafts to be withdrawn towards the discharge end of the machine together with the screw components which may then be changed or replaced; the smaller portions of the shafts remaining geared to the driving mechanism. As shown, a is a conveying and feeding section; b a mixing and kneading section; c a section for controlling the residence time of the materials in b; d is a coarse pitched section wherein degassing takes place at 2 and the materials are conveyed without substantial pressure to the extrusion section e.
