ABSTRACT:
A machine for cutting a relatively wide sheet of material into a plurality of relatively narrow strips to reduce bowing and camber in the cut strips is disclosed. The machine supports and moves the material along a path defined through the machine. The material initially engages a first pair of furrowing disc sets disposed on opposites sides of the sheet, which form a plurality of shallow furrows in the sheet as it passes therebetween. The material next engages a pair of slitting disc sets, also disposed on opposite sides of the sheet, which cut the relatively wide sheet into a plurality of relatively narrow strips as it passes therebetween. The slitting disc sets also engage and firmly hold the sheet near the furrows during the cutting process. Lastly, the material engages a second pair of furrowing disc sets which also engage and firmly hold the sheet near the furrows during the cutting process. Thus, each of the individual strips formed by this process have at least one furrow formed therein, which tends to minimize the occurrence of bowing and camber in the strips.
