         56 . Apparatus for trimming the edges of sheets, the apparatus including first, second, third and fourth saws, and a conveyor, the first saw arranged along the conveyor upstream in a direction of conveyance of the conveyor from the second saw, the second saw arranged upstream in the direction of conveyance of the conveyor from the third saw, and the third saw arranged upstream in the direction of conveyance of the conveyor from the fourth saw. 
     
     
         57 . The apparatus of  claim 56  wherein at least one of the first, second, third and fourth saws includes a motor for adjusting the position of the at least one of the first, second, third and fourth saws to cut at a non-zero angle to the direction of conveyance of the conveyor. 
     
     
         58 . The apparatus of  claim 57  further including a control system for automatically positioning the at least one of the first, second, third and fourth saws. 
     
     
         59 . The apparatus of  claim 56  wherein at least one of the first, second, third and fourth saws includes a motor for adjusting the position of the at least one of the first, second, third and fourth saws generally transversely of the conveyor. 
     
     
         60 . The apparatus of  claim 59  further including a control system for automatically positioning the at least one of the first, second, third and fourth saws generally transversely of the conveyor. 
     
     
         61 . The apparatus of  claim 56  wherein the conveyor comprises a conveyor for conveying stacked sheets. 
     
     
         62 . The apparatus of  claim 61  wherein the conveyor comprises a conveyor for holding the sheets together in stacks. 
     
     
         63 . The apparatus of  claim 62  wherein the sheets comprise sheets of wood veneer. 
     
     
         64 . The apparatus of  claim 56  further comprising a guide and a waste conveyor for guiding and conveying waste from the saws. 
     
     
         65 . The apparatus of  claim 56  wherein the first, second, third and fourth saws comprise circular saws. 
     
     
         66 . Apparatus for trimming the edges of sheets, the apparatus including first, second, third and fourth saws, and a conveyor for conveying the sheets past the first saw for trimming a first side edge of the sheets, then past the second saw for trimming a second side edge of the sheets, then past the third saw for splitting the sheets between the first and second side edges, and then past the fourth saws for removing a portion of the sheets between the first and second side edges. 
     
     
         67 . The apparatus of  claim 66  wherein at least one of the first, second, third and fourth saws includes a motor for adjusting the position of the at least one of the first, second, third and fourth saws to cut at a non-zero angle to a longitudinal extent of the conveyor. 
     
     
         68 . The apparatus of  claim 67  further including a control system for automatically positioning the at least one of the first, second, third and fourth saws. 
     
     
         69 . The apparatus of  claim 66  wherein at least one of the first, second, third and fourth saws includes a motor for adjusting the position of the at least one of the first, second, third and fourth saws generally transversely of the conveyor. 
     
     
         70 . The apparatus of  claim 69  further including a control system for automatically positioning the at least one of the first, second, third and fourth saws generally transversely of the conveyor. 
     
     
         71 . The apparatus of  claim 66  wherein the conveyor comprises a conveyor for conveying stacked sheets. 
     
     
         72 . The apparatus of  claim 71  wherein the conveyor comprises a conveyor for holding the sheets together in stacks. 
     
     
         73 . The apparatus of  claim 72  wherein the sheets comprise sheets of wood veneer. 
     
     
         74 . The apparatus of  claim 66  further comprising a guide and a waste conveyor for guiding and conveying waste from the saws. 
     
     
         75 . The apparatus of  claim 66  wherein the first, second, third and fourth saws comprise circular saws. 
     
     
         76 . Apparatus for trimming the edges of sheets, the apparatus including a first saw, a second saw, a conveyor, the first saw arranged along the conveyor upstream in a direction of conveyance of the conveyor from the second saw, and at least a first motor for adjusting at least one of the first and second saws to cut at a non-zero angle to a longitudinal extent of the conveyor. 
     
     
         77 . The apparatus of  claim 76  including first and second motors, the first motor for adjusting the first saw to cut at a non-zero angle to the longitudinal extent of the conveyor and the second motor for adjusting the second saw to cut at a non-zero angle to the longitudinal extent of the conveyor.
