PURPOSE:To improve the productivity by variably composing the angle and the interval of a pair of positioning plates, thereby accurately positioning and readily replacing the steps. CONSTITUTION:A pair of positioning plates 16 having variable angle and interval capable of being matched to the angle and size of various types of sector- shaped iron plates are mounted on a retainer 5 in a positioning station S2. The horizontal movements and opening angle of the plates 16 are regulated in response to the angle and size of the iron plates, and positioning pins 14 are replaced, the iron plates are contacted with them, and positioned. |
