Abstract

PURPOSE:To obtain a satisfactory molded article by detecting the moving speeds of a main screw at forwardly and reversely moving times and correcting the rotating speed of the screw of a feeder based on the detected value. CONSTITUTION:A rack 10 is secured to a main screw 3, and is moved in synchronization with the movement of the screw 3. A pulse encoder for generating a pulse upon rotation of the screw 3 is mounted on a pinion 11 engaged with the rack 10. A moving speed detector 12 detects the moving speed of the screw 3 by the number of pulses produced from the encoder during the moving of the screw 3 and produces an electric signal. The opening of the circuit is controlled by the magnitude of the voltage for operating an electromagnetic proportional flow rate control valve 13 to control the rotating speed of the hydraulic motor 6. Accordingly, the rotating speed of the screw 5 of the feeder 2 driven by the motor 6 becomes the rotating speed for supplying necessary quantity adapted for the moving speed of the main screw 3.
