PURPOSE:To perform the installation position of a material roll so efficiently by making a stopper touchable to a side face of the material roll installed in a chucking means,and controlling on-off operation of this chucking means and movement of the stopper. CONSTITUTION:When an air chuck 16 is made off by a control means, it is outputted to a control valve 24B, and an air cylinder 24 fixes a stopper 18 to a projecting position of a full line. In this state, if a material roll 14 is fitted in the air chuck 16 and this roll is thrust in direction of a frame 22 in parallel with a turning shaft 12, it comes into contact with the stopper 18. Under this state, the air chuck 16 is made on by a control means 20 via a control valve 16B, thereby restraining the material roll 14. Afterward, the control valve 24B is selected by the control means 20, and the stopper 18 is retreated to a retracting position in a two-dot chain line. With this constitution, installation positioning of the material roll 14 to the turning shaft 12 is thus completable. |
