  • Publication number: 20030207100
    Abstract: A waste sheet part forming apparatus forms a waste sheet part in a weblike heat transfer recording sheet supplied from a supplying apparatus. A slit apparatus cuts the recording sheet in the longitudinal direction into plural columns, and thereafter the cut recording sheets are sent to a winding apparatus. Sheet rolls formed in the winding portion in the winding apparatus are sent to a discharging portion and cores are supplied to the winding portion. The waste sheet extending between the winding portion and the discharging portion is cut by a cutting portion. An adhesive tape on the upstream side of the waste sheet is attached to a core in the winding portion and an adhesive tape on the downstream side is attached to the outer periphery of the sheet roll in the discharging portion.

  • Patent number: 6318554
    Abstract: An uncrumpling and cutting apparatus cuts a predetermined length of an end portion of a heat transfer recording sheet of a sheet roll obtained by winding the heat transfer recording sheet around an outer periphery of a shaft roll, and a lead sheet sticking apparatus sticks an end of a lead sheet to the end portion of the heat transfer recording sheet. A subshaft sticking apparatus sticks a subshaft to the lead sheet, and a lead sheet winding apparatus winds up the lead sheet to wrap-the sheet roll and the subshaft. A tying portion ties a combination of a sheet roll with a subshaft with a strip, thereby bundling the combination. Then the combination thus tied is packed in a package bag by a packaging portion. A transferring and mounting portion lays an even number of combinations as alternately reversing orientations thereof, and an encasing portion encases the combinations thus laid in a container.

  • Patent number: 6269859
    Abstract: A sheet roll forming system for forming sheet rolls by winding a heat transfer recording sheet around an outer periphery of a plurality of cores including a core supplying apparatus and a sheet roll discharge apparatus. The core supplying apparatus includes a cantilever shaft supporting the cores, a tray below the shaft and movable up and down in a direction of the shaft, and core stoppers on the tray where the shaft is an air shaft that can increase in diameter when air is supplied from a charge and exhaust apparatus. The sheet roll discharge apparatus includes the shaft supporting rolls of the recording sheet on the cores, a tray below the shaft, and a stopper on the tray.

  • Patent number: 6192957
    Abstract: A printing unit in a gravure printing portion prints a plurality of end marks on a web having a base film and a hot melt ink layer. The end marks printed on the web are dried by a drying apparatus. A sheet obtained from the web is wound around a roll shaft in a roll form by a sheet winding apparatus to form a sheet roll. The roll shaft is supplied from a roll shaft supplying apparatus to the sheet winding apparatus, and the sheet roll formed by the sheet winding apparatus is discharged from a discharging apparatus. The discharge apparatus includes a plurality of cradles in the vertical direction, a carry-out conveyor beside the cradles, a guide rail beside the cradles on the opposite side to the conveyor and arranged vertically, and receiving arms horizontally mounted on the rail and corresponding to the cradles. The arms move up and down on the rail and extend or contract horizontally from the cradles.

  • Patent number: 5851345
    Abstract: A heat transfer recording sheet producing apparatus and a roll shaft supplying apparatus. A web supplying unit supplies a web which is printed with end marks by a gravure printing unit. A drying unit dries the end marks, and then the web is wound onto a roll shaft in a sheet winding unit. The sheet winding unit is provided with roll shafts from the roll shaft supplying apparatus. After winding, a roll form is produced and is discharged to a discharge unit. The roll shaft supplying apparatus has a slit detecting unit to detect the presence or absence of a slit in a roll shaft and to detect the orientation of the roll shaft, and a gripping/turning unit operates on the roll shaft in response to a signal from the slit detecting unit. If a slit is detected and the orientation of the roll shaft is correct, the gripping/turning unit moves the roll shaft to a second discharge unit which supplies the roll shaft to the sheet winding unit.
