A backing pad arrangement for an abrading system, and the abrading system

Abstract

The application relates to a backing pad arrangement suitable for an abrading system. The backing pad arrangement comprises a backing pad (413, 513, 523), and an additional layer (418, 518, 528) or an abrading article (417, 527) adapted to be attached to the backing pad (413, 513, 523) with at least one fixing member (319, 419, 519, 529), which at least one fixing member (319, 419, 519, 529) is hollow in its longitudinal direction. The application further relates to the abrading system comprising the backing pad arrangement according to the application.

1 . A backing pad arrangement for an abrading system, the backing pad arrangement comprising a backing pad, wherein a lower surface of the backing pad comprises at least one opening, wherein the at least one opening is adapted to receive a fixing member, and the backing pad arrangement further comprises:
 an additional layer adapted to be attached to the backing pad, which additional layer comprises an upper surface, a lower surface and at least one opening which extends through the additional layer, and the additional layer is attached to the backing pad with at least one fixing member,   wherein the at least one fixing member is hollow in its longitudinal direction in order to transport debris with air through the at least one fixing member.   
     
     
         2 . The backing pad arrangement according to  claim 1 , wherein the additional layer is attached to the backing pad with two or more fixing members. 
     
     
         3 . The backing pad arrangement according to  claim 1 , wherein the additional layer is attached to the backing pad with one fixing member arranged in the center of the backing pad. 
     
     
         4 . The backing pad arrangement according to  claim 1 , wherein the fixing member is of screw-, snap hook- or expanding type. 
     
     
         5 . The backing pad arrangement according to  claim 1 , wherein the backing pad comprises at least one air inlet conduit for conducting air to an abrading surface. 
     
     
         6 . The backing pad arrangement according to  claim 1 , wherein the additional layer comprises a soft intermediate layer between the upper surface and the lower surface of the additional layer. 
     
     
         7 . The backing pad arrangement according to  claim 1 , wherein the lower surface of the additional layer comprises abrasive particles. 
     
     
         8 . The backing pad arrangement according to  claim 1 , further comprising an abrading article adapted to be attached to the additional layer. 
     
     
         9 . The backing pad arrangement according to  claim 1 , wherein the backing pad comprises a suction conduit formed by the at least one opening of the additional layer and an additional opening of a cover plate of the backing pad. 
     
     
         10 . An abrading system comprising an abrading apparatus, wherein the abrading system further comprises a backing pad arrangement according to  claim 1 . 
     
     
         11 . The abrading system according to  claim 10 , wherein the abrading system comprises a debris extractor system adapted to provide suction pressure and to remove debris formed during abrading work. 
     
     
         12 . The abrading system according to  claim 11 , wherein the debris extractor system is arranged to guide debris away from the additional layer and the abrading surface. 
     
     
         13 . The abrading system according to  claim 11 , wherein the debris extractor system is adapted to guide debris via at least one of the following:
 the additional layer,   the abrading article,   the backing pad,   the fixing member(s),   opening(s) of the additional layer,   opening(s) of the abrading article, and   opening(s) of a cover plate of the backing pad.   
     
     
         14 . The abrading system according to  claim 10 , wherein
 opening(s) of the additional layer, and   opening(s) of the cover plate of the backing pad are connected in order to form conduit(s).
