ABSTRACT:
A hydraulic ram operated extruder having an extrusion die from which an extradate is delivered and a motor driven cutter at the die to sever the extrudate repeatedly to produce individual pieces of extradate. The hydraulic fluid circuit including a pump and control valves delivers hydraulic fluid to the ram of the extruder at a substantially constant volume flow rate. A control device responsive to the speed of advance of the ram in the extruder controls the motor which drives the cutter to produce blanks of substantially equal volume.
