Device for processing flat workpieces

Abstract

The invention is related to a device far processing substantially flat workpieces, said device comprising a transport surface for transporting each of the workpieces through the device, and a processing unit, comprising of a processing element having an abrasive surface and being movable parallel to the transport surface in order to come into contact with each of the workpieces to be processed, a driving shaft and a carrier connected thereto for supporting the processing element, the driving shaft being tranversally positioned with respect to the carrier and the processing element comprising support members for supporting the abrasive surface, said support members being positioned at an angle of less than 90° with respect to the processing element, by which a multi-sided processing of the workpiece is achieved.

1 . A device for processing substantially flat workpieces, said device comprising a transport surface for transporting each of the workpieces through the device, and a processing unit consisting of a processing element having an abrasive surface and being moveable parallel to the transport surface in order to come into contact with each of the workpieces to be processed, a driving shaft and a carrier connected thereto for supporting the processing element, the driving shaft being transversally positioned with respect to the carrier, characterised in that the processing element comprises support members for supporting the abrasive surface, said support members being positioned at an angle of less than 90° with respect to the processing element.  
     
     
         2 . A device according to  claim 1 , in which the support members are directed at least radially with respect to the driving shaft of the carrier.  
     
     
         3 . A device according to  claim 2 , in which the support members are substantially radially directed with respect to the driving shaft of the carrier.  
     
     
         4 . A device according to  claim 2  or  3 , in which the support members are substantially inclined towards and/or away from the driving shaft.  
     
     
         5 . A device according to any of the claims  1 - 4 , in which the processing element comprises brush hairs as support members.  
     
     
         6 . A device according to  claim 5 , in which the brush hairs are impregnated with abrasive particles.  
     
     
         7 . A device according to  claim 5 , in which the brush hairs are made of steel, preferably stainless-steel.  
     
     
         8 . A device according to any of the claims  1 - 7 , in which the processing element further comprises a web of nonwoven synthetic fibres, provided with sanding grains.  
     
     
         9 . A device according to any of the claims  1 - 8 , in which the processing element further comprises brush hairs impregnated with abrasive particles or made of nylon, positioned at right angles to the processing element.  
     
     
         10 . A device according to any of the claims  1 - 9 , in which the processing element is unremovably connected to the carrier.  
     
     
         11 . A processing element for application in a device for processing substantially flat workpieces according to any of the claims  1 - 10 .
