PURPOSE:To eliminate dispersion on products by controlling a take-off speed, by a method wherein a measuring pot, an opening and closing cylinder for raw materials and automatic take-out speed control board are arranged on the way of sending the raw materials to a heating cylinder, the opening and closing cylinder is turned ON/OFF by an upper limit set up value and lower limit set up value of the measuring pot and an extrusion rate is calculated by a period of time extending to the OFF from the ON. CONSTITUTION:When the lower limit value is attained by deciding the lower limit value and upper limit value, raw materials 1 are taken into a measuring pot 2 by opening an opening and closing cylinder 3 by turning 2 it ON, and when the upper limit value is attained, taking-in of the raw materials is suspended by closing the cylinder 3 by turning it OFF. Then a period of time extending from a moment when the cylinder 3 turns OFF after the cylinder 3 has been turned ON up to a moment when the cylinder 3 turns ON is measured. The measured value is applied to a CPU in an automatic take-out speed control board 12. Specific weight and viscosity of the raw materials are set up beforehand on the speed control board 12. An extrusion rate and take out speed are calculated by those values in the CPU and the take-off is controlled. |
