          Application 08/236,570                                                      


                                    THE REJECTION                                     
               Claim 1 stands rejected under 35 U.S.C.  103 as being                 
          unpatentable over the admitted prior art in view of the Japanese            
          reference.                                                                  


               The rejection is explained in the Examiner's Answer.                   
               The opposing viewpoints of the appellants are set forth in             
          the Brief.                                                                  
                                       OPINION                                        
               The appellants' invention is an improvement to coating                 
          machines in which the coating to be applied to a web issues from            
          a passageway running through a die.  The claim states that the              
          die terminates at the web in an upstream bar with a lip formed as           
          a land and a downstream bar with a lip formed as a sharp edge,              
          and that the passageway is a slot defined by these upstream and             
          downstream lips.  According to the appellants' specification, a             
          common problem in this type of device is the occurrence of                  
          streaks in the coated layer, caused by dried liquid residue                 
          collected on the lips of the die near the coating bead.  The                
          appellants assert that this is cured by their invention, which is           
          set forth in the claim as                                                   
               a low surface energy covering applied to the surface of                

                                          3
