Abstract

A screw 30 feeds material to the rolls 16, 18, of the machine, which are mounted for movement along planes which are oblique to one another and to a centre plane X, of the machine to give improved force distribution to the frame 50 of the machine and to give ready access to the machine for cleaning purposes. The planes of movement may be at angles A, B of 15 DEG to 60 DEG to a plane perpendicular to the plane X. The movement is effected by the roll bearings 58, being displaceable along slots 60 of the frame 50, by hydraulic cylinders 62 which also act to determine the nip between the rolls 16, 18. A sensor 75 may act to control the speed of the rolls 16, 18, or of the extruder screw 30, or the size of the roll nip by regulating the hydraulic pressure of cylinders 62, or the heat transfer of the rolls 16, 18, or of the extruder die 46. <IMAGE>
