<p>An injection moulding machine includes a hopper 11 having at least two inlets 12, 13. The inlet 13 comprises two tubes 14, 15 hingeably connected by a joint 16 operable by a pneumatic cylinder 18. In use, tube 15 is held at an angle with respect to tube 14 (phantom lines) and waste plastics material, e.g. PVC or thermoplastic rubber, is placed into scoop 17. At intervals cylinder 18 is actuated to swing tube 15 into line with tube 14 so that the waste material falls through the hopper 11 and into a lower housing for melting and subsequent injection. A third inlet 21 may be provided for other plastics waste material. Approximately 6% waste material, supplied through inlet 13, may be mixed with unused plastics material fed through inlet 12. <IMAGE></p> |
