Abstract

The grinding ring (1) is fixed to the support plate (2) coaxial with the center lengthwise axis. The end sides (3) of the grinding ring have reinforcement layers (4,4') between which is a grinder layer (5) joined to them. The support plate has an annular flange (18) with outer surface (21) radially positioned in relation to the center lengthwise axis. A reinforcement layer is fixed to the outer surface and overlaps by means of an adhesive layer (22).
