PURPOSE:To improve the product quality and productivity, by setting plural disk shoes in a turntable, which is freely rotatable around its axis and vertically shiftable, at readily replaceable positions. CONSTITUTION:An arm 3a is turned around to a prescribed position and is fixed therein; a turntable 11, provided with plural through holes on the same radius from its center, is turned around so as to bring a disk-shoe unattached through hole 13a to a position facing to an axile 4a of the arm 3a. The table 11 is then raised for inserting a nut 4a' into the hole 13a, and at the same time, a pin 14 is fitted into a small hole bored in a disk shoe 2a; the nut 4a' is then detached, the table 11 is descended, and the disk shoe 2a is replaced. By the present apparatus, the disk shoe can be replaced without carrying it by hand, so that the working time for replacement is shortened. |
