               Application No. 10/191,311                                                                                        



               as to hold the paper being cut against bunching, tearing or splintering, and which rollers                        
               are so oriented as to produce minimum interference with cutting action.  Figure 1 is a                            
               side view of a cutter with parts shown in section taken on line 1-1 of Figure 2.  Figure 2                        
               is a view of the cutter taken at right angles to Figure 1 looking upwardly at the bottom of                       
               Figure 1.  Figure 3 is an enlarged transverse sectional view taken on line 3-3 of Figure                          
               1.                                                                                                                


                      Baker teaches that the pair of rollers 24 are journalled upon rivets 26.  As shown                         
               in Figure 3, the rollers 24 are of a diameter greater than the width of the members 14                            
               and the axis of rotation thereof adjacent the narrow edge of the members 14 permits                               
               projection of a part of each roller from the narrow edge of member 14 while the                                   
               diametrically opposite part of each roller lies alongside the plates 14.  The rollers 24                          
               extend at an angle to each other, as illustrated in Figure 3, with their inner faces                              
               substantially parallel to the inclined faces 22 of the parts 14.  Thus the projecting                             
               portions of the rollers 24 are spaced apart only a small distance.  The rollers 24 are                            
               provided with frusto-conical outer surfaces 28 providing only narrow peripheral portions                          
               30 to limit the width of the contact of the rollers with the work.  Baker teaches (column 3,                      
               lines 14-33) that:                                                                                                
                      The tool is usually employed by moving the same endwise in the direction of the                            
                      handle 15 and, therefore, it will be seen that the rollers press the work in advance                       
                      of the cutting action of the blade and in such a direction as to smooth the work.
