Abstract

PURPOSE:To regulate the outer diameter of an extrusion molded product automatically, in high accuracy, by evaluating the signal generated when the outer diameter deviates from a reset value, and controlling the driving motor of the extrusion screw or of the take-up roll by the signal after evaluation.
