Abstract:
A slitting mechanism for use in a card cutting machine having a box for keeping a pile of sheets, a pick-up roller for forwarding a top sheet from the pile of sheets in the box, a roller for conveying the sheet forwarded by the pick-up roller, and a cutting device for cutting the sheet conveyed by the roller to a card shape, the cutting device including a cutter for cutting the sheet in a direction transverse to an axis extending along the path of travel of the top sheet, said slitting mechanism comprising upper and lower rotating shafts spaced apart from and extending parallel to each other, said rotating shafts extending transverse to the path of travel of the sheet, plural upper cutting disks fixed on said upper rotating shaft, and plural lower cutting disks fixed on said lower rotating shaft, each said lower cutting disk having a cutting edge for contacting a cutting edge of a respective one of said upper cutting disks to form a pair of cooperating cutting disks, and said slitting mechanism further including a plate having a sharp tip for clearing chips from a space between a pair of adjacent lower cutting disks, said plate being secured such that said sharp tip extends within said space between said pair of adjacent lower cutting disks so that said sharp tip will contact a chip caught in said space during operation of said slitting mechanism for making a stripe and a peak on the chip to shorten an effective width of the chip and allow the chip to drop down from the space and away from the cutting disks.
