Abstract

1,105,040. Multi-screw extruders. F. PRANDI, and G. P PRANDI; 15 Dec., 1965 [30 Sept., 1965], No. 53140/65. Heading B5A. An extrusion moulding machine comprises a plurality of screws 4 individually housed in barrels 5 arranged around a common axis, the screws being fed from a common hopper 2, see also Fig.: 2 (not reproduced), and discharging into and through a common outlet 6. A motor (not shown) which drives the screws may be connected selectively to one or more screws by friction clutches, mechanical or electromagnetic, but is preferably connected by a gear coupling. Each screw 4 may be axially extended by a chuck (41), Fig. 4 (not shown), which is driven via a sleeve (5) and gears (11, 12) when an axially movable gear (17) on chuck (41) is engaged with a gear (16) on sleeve (5). In a modification, Fig. 5 (not shown), a speed changer (18) is added which has an output shaft (21) selectively connectible to chuck (41). The outputs from barrels 5, Fig. 1, may be combined in an extrusion nozzle attachable to outlet 6, see also Fig. 3 (not reproduced), and a multi-coloured product may be formed by using this head and suitably subdividing the feed zone of the screws.
