ABSTRACT:
The apparatus for longitudinally slitting sheet material comprises a supply assembly for supplying for unrolling a roll of the sheet material, a table surface for receiving the sheet, a re-rolling cradle for receiving a cut portion of the sheet and driven to roll the cut portion into a roll and a slitting assembly for slitting the sheet in a longitudinal direction at least at one position across its width. The slitting assembly comprising an elongate support housing extending across the table transverse to the longitudinal direction of the sheet, at least one slitting knife member mounted on the housing for slitting the sheet, the knife member being movable along the housing for adjustment of the position of the knife member across the sheet so as to vary a width of the portion to be cut. The knife member includes a blade support carried on the housing for sliding movement and an elongate drive shaft extending across the table which is driven at one end. The blade support includes a driven sprocket for receiving drive from shaft and a driven sprocket attach to the disk blade. The drive sprocket is slidable along the shaft with movement of the blade support along the housing and the drive sprocket and the drive shaft are shape in cross-section such that rotation of the drive shaft causes rotation of the drive sprocket for driving the disk blade.
