Abstract (en)
A backup pad for supporting a flexible grinding disc, comprises a hub which is to be connected to a rotary spindle, as well as a concentric support disc having a support face onto which the grinding disc is to be supported. The support disc is provided with ventilating holes which open out on the supporting face, for providing an air flow between the facing surfaces of support disc and grinding disc. Also, the support face of the support disc is provided with support protrusions for supporting the grinding disc, between which protrusions (4) an air gap (12) is available. <IMAGE>
