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 (4
