ABSTRACT:
A treatment disk for devices for roughening or treating surfaces of stone floors, wherein hammer-like treatment points are mounted on the treatment disk opposite each of respectively semicircular slideways of the treatment disk. This shape makes it possible for an operation of a treatment point to cause the treatment disk to make a circular movement in the slideway and not, as previously known, a jumping or chattering movement as in a compressed air jack. The treatment disk is preferably made in three parts, so that the cutout has an overall shape resembling a three-leaf clover and the treatment points are offset by approximately 20.degree. with respect to the symmetry axes of the clover leaf. This shape has proven to be particularly effective.
