          Application No. 09/358,666                                                  
               The roll surface of each of the rolls 30, 31 has a                     
               shallow bevel or frusto-conical configuration with the                 
               larger diameter at the locality of proximity of the two                
               roll surfaces . . . .  By reason of the preferably very                
               narrow axial dimension of the roll surfaces, as well as                
               their taper, all possibility of rolling metal contact                  
               with the advancing strip surfaces is limited strictly                  
               to the edge corner regions where smoothing function is                 
               desired.  [Column 5, lines 28-43.]                                     
          Wegner further states that                                                  
               . . . very preferably the work rolls are relatively                    
               narrow in the transverse direction of the strip, in                    
               that for example in one embodiment the total width of                  
               the two bevelled work faces together was about                         
               seven-eighths inch.  By reason of their bevelled or                    
               tapered configuration, at a relatively small angle such                
               as 2° to 5° to the path plane, e.g., 3° for metal 0.008                
               inch thick and upwards, engagement with the strip is                   
               limited essentially to the corner area, i.e., to the                   
               actual deformed locality.  [Column 13, lines 5-15.]                    
               The linchpin of the standing rejection of claim 24 as being            
          anticipated by Wegner is the examiner’s determination that                  
          Wegner’s work rolls 30, 31 have “substantially cylindrical”                 
          exterior surfaces as called for in claim 24.  More particularly,            
          the examiner takes the position (answer, page 4) that                       
               [a]lthough Wegner teaches that the roll surface of each                
               of the rollers (30, 31) has a shallow bevel or frusto-                 
               conical configuration[,] this does not mean that the                   
               rollers cannot be substantially cylindrical.  The term                 
               “substantially” . . . allows room for slight deviation.                
               Wegner teaches that the roll surface of each of the                    
               rollers has a shallow bevel (col. 5, lines 28-29),                     
               which by interpretation may be within the range of a                   
               “substantially” cylindrical roller.  A shallow bevel                   
               can range anywhere from a minuscule dimension such as a                
               nanometer to a larger dimension that would not                         
                                          4
