Grinding device

Abstract

A grinding device includes a drivable backing pad and a flexible grinding element held on the backing pad by suctioning and is provided with abrasive grains. The grinding device is designed such that the grinding element, in the form of a grinding belt, protrudes circumferentially with respect to the backing pad, the abrasive grains covering the entire area of the grinding element.

         11 . A grinding device, comprising;
 a drivable backing pad; and   a flexible grinding element provided with abrasive grains and held on the backing pad by suction,   wherein the flexible grinding element is a grinding belt projecting circumferentially relative to the drivable backing pad, wherein the abrasive grains cover an entire area of the flexible grinding element.   
     
     
         12 . The grinding device of  claim 11 , wherein the drivable backing pad comprises a rigid connecting piece, an elastic intermediate layer held on the rigid connected piece, a support plate held on a side of the elastic intermediate layer facing away from the rigid connecting piece, wherein the flexible grinding element rests against the support plate. 
     
     
         13 . The grinding device of  claim 12 , wherein the elastic intermediate layer consists of a foam material. 
     
     
         14 . The grinding device of  claim 12 , wherein the support plate consists of an elastomer. 
     
     
         15 . The grinding device of  claim 11 , wherein the drivable backing pad is screwed to a driven connecting element. 
     
     
         16 . The grinding device of  claim 15 , wherein a thread pairing of the driven connecting element and the drivable backing pad is self-locking. 
     
     
         17 . The grinding device of  claim 11 , wherein the drivable backing pad is rectangular in plan view. 
     
     
         18 . The grinding device of  claim 11 , wherein the drivable backing pad is convexly curved on a side of the drivable back page facing the flexible grinding element. 
     
     
         19 . The grinding device of  claim 15 , wherein the connecting element comprises a radially oriented suction line that merges into an axial suction line, wherein the axial suction line is continued by the drivable backing pad. 
     
     
         20 . The grinding device of  claim 11 , wherein the drivable backing pad is driven by a toothed belt connected to a drive.
