In a depressed-center abrasive wheel assembly (58) a reinforcement layer (14) of polygonal shape is located between a front face (20) of the abrasive wheel (10) and a front flange (50). The reinforcement layer (14) is dimensioned to entirely cover the depressed center portion (32) of the wheel (10). An example of polygonal reinforcement layer (14) has a hexagonal shape and is made of fiberglass cloth. A polygonal shape reinforcement layer (14) 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.
L'invention concerne un dispositif de meule abrasive à moyeu déporté (58), comportant une couche de renfort (14) de forme polygonale disposée entre une face avant (20) de la meule abrasive (10) et une flasque avant (50). La couche de renfort (14) est dimensionnée de manière à recouvrir entièrement la partie à moyeu déporté (32) de la meule (10). Un exemple de couche de renfort (14) polygonale possède une forme hexagonale et est réalisé en toile de fibre de verre. Une couche de renfort (14) polygonale peut également être employée entre la flasque avant et la face avant sur un dispositif de meule abrasive faisant intervenir une meule sans renfort intérieur.
