Abstract

PURPOSE: To permit discs carrying blades inserted therein to be separated and positioned while being held aginast inclination by providing a chuck for holding the discs.
CONSTITUTION: Discs 4a to 4d are stacked on a chuck 1 and positioned with positioning pins 2, and then a number of blades 5 are inserted through grooves formed in the discs 4a to 4e and secured thereto. Subsequently, a stepped shaft 3 is raised, whereby pulling shafts 6 are raised. As a result, the disc 4a is separated by the first shoulder of the stepped shaft 3, and at the same time support arms 10a of a lift block 7a being raised by the pull-up shafts 6 are forced out toward the axis of the stepped shaft 3 by cams 9, thus bringing a plate spring mounted on the underside of the support arms 10a into contact with the upper surface of the disc 4a. Thus, even if fluctuations of the frictional force between the grooves of the disc 4a and the blades 5 are produced, the disc 4a can be separated without being inclined since the support arms 10a are in contact with the upper surface of the disc 4a.
