  • Patent number: 7100657
    Abstract: A sheet slitter winder that uses a sheet slitter to slit a wide sheet into a plurality of sheets of predetermined width, and winders to wind the slit sheets onto winding cores. Touch rollers contact the winding rolls. Temporary sheet-holding means have a sheet-retaining plate that can be contacted with and separated from the touch rollers and can temporarily hold a slit sheet against an outside peripheral surface of a touch roller at a point upstream of a point of contact between a touch roller and a roll. Cutting means are used to cut widthwise across the slit sheets thus held in place.
