PURPOSE:To provide the above device having a high response speed and capable of accurately groping an emitting amount regardless of the cross-sectional shape of a molded product. CONSTITUTION:An operational control part 50 constituted so that the number of rotations of the motor 20 driving an extruder 10 is controlled by an outer diameter sensor 30 successively detecting the outer diameter of the extrusion molded product from an extruder 10 extruding a supplied pellet like raw material from a nozzle to produce a molded product having a predetermined shape dimension and a speed sensor 40 successively detecting the extrusion speed of the molded product 90 to control an emitting amount is provided. |
