Method of manufacturing an abrasive member, in particular rotary abrasive disc, and abrasive member, in particular rotary abrasive disc

A method of manufacturing an abrasive member having the shape of a disc, the method comprising:

• (a) arranging a reinforcing member, adapted for releasable attachment to a rotary shaft of a rotary power tool so as to transmit mechanical force from the rotary power tool to the abrasive member, into a mold:
• (i) between a layer of curable abrasive resin compound and a backing member, and (ii) positioned such that:
• (A) at least a section of the reinforcing member is in direct physical contact with the curable abrasive resin compound, (B) the curable abrasive resin compound forms a discrete, layer that is coplanar to the backing layer, (C) the reinforcing member is at least partially covered by the backing member, and (D) at least a section of the backing member is in direct physical contact with the curable abrasive resin compound;
• and
• (b) bonding the reinforcing member and the backing member by curing the curable abrasive resin compound, wherein the cured abrasive resin compound forms an abrasive layer of the disc-shaped abrasive member so that the reinforcing member:
• (i) becomes bonded to the abrasive layer where the reinforcing member is not covered by the backing member and (ii) creates a substance-to-substance bond with the backing member where the reinforcing member is covered by the backing member.
