          Application No. 09/067,811                                                  


                                     BACKGROUND                                       
               The appellants' invention relates to a device for                      
          conveying thin workpieces used in the printing technology                   
          field.  An understanding of the invention can be derived from               
          a reading of exemplary claim 1, the sole independent claim on               
          appeal, reproduced below.                                                   
                    1. A device for conveying thin workpieces used in                 
               the printing technology field, comprising:                             
                    at least one moveable conveying element having an                 
               electrically insulating contact surface for supporting at              
               least one of the workpieces as it is being conveyed, said              
               conveying element formed without electrode material;                   
                    a d.c. voltage source supplying at least a first                  
               voltage potential; and                                                 
                    a plurality of contacts disposed to engage said                   
               contact surface of said conveying element, said plurality              
               of contacts including a group of contacts electrically                 
               connected to said first voltage potential;                             
                    said plurality of contacts for applying regions of                
               charge density to said conveying element to hold the                   
               workpiece on said contact surface of said conveying                    
               element.                                                               


               The prior art references of record relied upon by the                  
          examiner in rejecting the appealed claims are:
