Abstract

PURPOSE:To decrease the short-term, and long-term variations in the extrusion rate of a resin, by providing a means for controlling rotational speed of screw in responce to the resin pressure at the outlet of the extruder, and a means for controlling the averge rotational speed of screw by the average value of the rotational speed.
