PURPOSE:To obtain the captioned device capable of filling a material into the groove of a screw so as not to produce ununiform plasticization upon plasticizing by a method wherein the feeder screw is supplying the material commensurating with the number of revolutions of the main screw upon measuring and injecting respectively. CONSTITUTION:When a signal 30 indicating that the measurement is being effect operates a relay 31, the A contact 32 thereof is connected and the set value of a volume 33 setting the ratio of number of revolutions of the main screw 22 to the feeder screw 24 is acted on the controller 25 of the feeder screw 24. When a signal 26 indicating that the injection is being effected operates a relay 27, the A contact 28 is connected and the set value of a setting volume 29 setting the revolving speed of the screw 24 under injection is acted on the controller 25. |
