          Appeal No. 1997-4279                                                        
          Application No. 08/486,702                                                  


               We reverse the rejection of claim 15 under 35 U.S.C.                  
          103 as being unpatentable over the German reference in view of              
          Klebanow and Wahnschaff.                                                    


               Claim 15, dependent from claim 1, adds the feature of "at              
          least one vacuum belt connected to a source of low pressure                 
          for removing the overlapped sheets and adhesive coating                     
          material from the transferring means."                                      


               Clearly, the Wahnschaff document (Fig. 1) reveals that                 
          the utilization of a suction conveyor 21 in the coating art is              
          a known expedient for transporting coated sheets of material                
          such that the sheets cling to the conveyor.  However, as can                
          be readily discerned from the Wahnschaff disclosure, suction                
          is applied exclusively to the upper flight of a conveyor belt               
          35, downstream of a coating station.  Thus, even if the                     
          apparatus of the German reference incorporated a suction                    
          conveyor it would appropriately be applied downstream of a                  
          coating station, following the teaching of Wahnschaff.  Thus,               
          the combined teachings would not effect a vacuum belt for                   
          removing overlapped sheets and adhesive coating material "from              
                                         10
