ABSTRACT:
A slitting mechanism for a card cutting machine including a pair of rotating shafts having conveying rollers and cutting disks with cutting edges secured thereto. The slitting mechanism also includes a plate positioned in the space between adjacent cutting disks on one of the rotating shafts. The plate includes a sharp tip for contacting and dropping down chips caught in the space between adjacent cutting edges. Moreover, a sliding clutch is utilized to prevent rubbing and damaging of a sheet when the conveyance of the sheet is temporarily stopped. The sliding clutch is fitted on the drive shaft of the pair of rotating shafts for transferring power from a power source to the drive shaft. The clutch slides when a load is applied to the rotating shafts to stop the transfer of power to the rotating shafts and to prevent the conveying rollers from rubbing and damaging the sheets.
