Abstract
In a depressed-center abrasive wheel assembly a reinforcement layer of polygonal shape is located between a front face of the abrasive wheel and a front flange. The reinforcement layer is dimensioned to entirely cover the depressed center portion of the wheel. An example of polygonal reinforcement layer has a hexagonal shape and is made of fiberglass cloth. A polygonal shape reinforcement layer can also be employed between the front flange and the front face in an abrasive flat wheel assembly that employs a wheel without internal reinforcement.

A depressed center abrasive wheel assembly, comprising:
- (a) a wheel having a rear face, a front face and an outer wheel diameter, said rear face including a raised hub and a flat rear wheel region, said front face including a depressed center and a flat front wheel region;
- (b) a front flange at said depressed center;
- (c) a rear flange at the rear face of the wheel, said rear flange including a recessed region at the raised hub;
- and
- (d) a reinforcement layer, applied to the front face of the wheel, concentric with the wheel and covering the depressed center of the wheel, wherein said reinforcement layer is a pad, a mat or a cloth that has a polygonal shape selected from the group consisting of triangle, pentagon, hexagon and octagon, and a polygon largest diameter that is no greater than about 75% of said outer wheel diameter.
An abrasive wheel assembly comprising:
- (a) an abrasive wheel having a rear face, a front face and an outer wheel diameter;
- (b) a front flange at the front face;
- (c) a rear flange at the rear face;
- and
- (d) a reinforcement layer, concentric with the wheel and applied to the front face of the wheel, wherein said reinforcement layer has a polygonal shape selected from the group consisting of pentagon, hexagon, and actagon, and a polygon largest diameter that is no greater than about 75% of said outer wheel diameter.
