Abstract
A waferizing apparatus having a rotatable disc. There are knife carriers mounted on the disc with spaced openings between the carriers. Openings in the disc correspond to the openings in the carrier and there is a knife associated with each opening. A knife clamp is bolted to the carrier to clamp each knife in position. Each knife clamp is urged resiliently inwardly against the carrier to clamp each knife in position in the apparatus. An expandable device can expand to separate the clamp and the carrier to permit removal of each knife.
