A main extruder and a side arm extruder are used in the extrusion of plastics with small amounts of additives or other small substances to be admixed. A minor portion of the plastic material is premixed with small quantity additive substances in a side arm extruder. The premixed material is discharged from the side arm extruder into the main extruder and there mixed with a major portion of feed material.
