で、常に最適な初期設定を行うことができる。As described above, according to the present embodiment, the material extrusion speed and the material extrusion speed of each extruder 1 are determined based on the difference between the measured width of each of the belt-shaped rubber materials A and B and the target value and the amount of change per unit time. Since the material guide width of the guide mechanism 3 is controlled, the increase and decrease of the material extrusion speed and the material guide width can be stabilized in a short time, and the width of each of the belt-shaped rubber materials A and B can be quickly brought close to the target value. be able to. Further, since the data relating to the material extrusion speed and the material guide width when the width of each of the belt-shaped rubber materials A and B is stabilized for a certain period of time or a predetermined number of times of measurement is stored as the next initial setting data, the optimum initial value is always stored.
