Abstract

An apparatus for feeding dough moulding composition to the barrel 1 of an extruder or injection moulding machine comprises a reservoir eg hopper 5 having means eg piston 7 therein to urge moulding composition from said reservoir to said barrel 1, a channel 8 connecting said reservoir and barrel 1, said channel 8 having a variable volume portion eg ancillary piston 12 and cylinder 11 and an isolating valve 9 for closing the channel 8 between the reservoir 5 and said variable volume portion 11, 12 so that when said channel 8 is open, moulding material flowing through the channel 8 to the barrel 1 will at least partly increases the volume of said portion eg by pushing back the piston 12 so as to store moulding material therein, the arrangement being such that on closing said isolating valve 9 and contracting said variable volume portion, eg by advancing the piston 12 the flow of moulding composition to the barrel 1 is maintained from said portion 11, 12 for at least as long as is necessary to replenish the reservoir 5. <IMAGE>
