  • Patent number: 8015904
    Abstract: The present invention provides a die holder with one or more pre-located recessed areas or voids into which cutting dies can be quickly and easily inserted and secured. The die holder mounts quickly to the cylinder, and can be quickly removed for alternative operations. The die holder can be made according to the operator needs for different types, sizes and positions of dies. Unused voids can be filled with ‘blank’ blocks to achieve a consistent or uniform surface height for the full 360 degree area of the die cylinder. The present invention further provides a removable scrap control apparatus that is not attached permanently to the die cylinder on which it is used, which permits the use of a multiple blade die or a plurality of single blade dies on the same die cylinder without requiring permanent holes, slots or other means to accommodate the scrap control apparatus on the die cylinder or anvil cylinder.

  • Patent number: 7900542
    Abstract: A knife holder assembly for a rotary cutting machine includes a holder with a top portion and side portion each including an opening, and an adjusting member with a top portion and side portion each including an opening. The inner side portion of the holder is tapered at an angle substantially the same as the side portion of the adjusting member. A fastener can be inserted through the top portion opening of the holder and the top portion opening of the adjusting member thereby moving the adjusting member in a direction away from the outer side portion of the holder to clamp an inserted knife between the backing portion and the outer side portion of the holder.

  • Patent number: 6112884
    Abstract: A web-product delivery system includes a top belt system with at least one top belt assembly supported and movably adjustable on a carriage. The top belt assembly includes a front assembly and a rear assembly. Both the front assembly and rear assembly include at least one idler roller assembly, and a bracket slidably attached to the carriage to allow the top belt assembly to be positioned and adjusted along a product path while product is moving along the product path. The idler roller assembly may include a roller rotatably attached to an arm, the arm pivotably attached to a bracket, a pivot shaft attached to the bracket and slidably receiving a load-bias threaded adjusting rod. The adjusting rod is screwably attached to the arm to allow the arm to rotate about the bracket through a vertical plane when the adjusting rod is turned. The web-product delivery system further includes a transition throw-off and vertical adjustment assemblies which may be operated while running.

  • Patent number: 5893314
    Abstract: A knife holder assembly for a rotary cutting machine includes a holder with a top portion and side portion each including an opening, and an adjusting member with a body portion and an extender. The extender is adapted to extend through the side portion opening and has a backing portion at its end. The body portion has an indention with a tapered sidewall for allowing a fastener to be inserted through the top portion opening and contact the tapered sidewall thereby moving the adjusting member in a direction away from the side portion to clamp an inserted knife between the backing portion and the side portion.

  • Patent number: 5868057
    Abstract: The invention provides a perforation cutting rule for a rotary cutting machine and method of operating the same. The cutting rule has a length, height and thickness and includes a plurality of dovetail-shaped gaps formed along a longitudinal edge to define a plurality of dovetail-shaped cutting teeth. Each tooth includes an outer cutting end and an inner base end, the outer cutting end having a length greater than an inner base end. As the cutting end cuts through multiple sheets the angled sides of the dovetail-shaped teeth provide a relief area to prevent the sheets from bunching or pulling against the teeth during the cutting operation.

  • Patent number: 5595093
    Abstract: A method of forming a rotary cutting die includes the following steps. A curved cutting rule transfer plate including an inner surface and an outer surface is provided. A cutting rule channel is formed in the transfer plate, and defines a predetermined design. A cutting rule having a cutting edge and a support edge is placed in the cutting rule channel. The support edge of the cutting rule extends from the inner surface of the transfer plate. A translucent rotary die place is formed on the inner surface of the transfer plate. The support edge of the cutting rule extends into and is supported in the rotary die plate. The transfer plate is then removed from the rotary die plate.

  • Patent number: 5505125
    Abstract: A rotary embossing die includes a curved metallic plate having an inner and an outer surface. An embossing design is etched on the outer surface of the metallic plate and an epoxy-based support plate is formed on the inner surface of the metallic plate. The metallic plate and the support plate preferably cooperate to define a shoulder. Die clips positioned around the shoulder are used to fasten the embossing die to the die cylinder of a rotary embossing machine. The metallic plate can be formed from brass or magnesium, and is preferably curved to any suitable radius.

  • Patent number: 4896573
    Abstract: An apparatus for removing scrap around the die cut blanks in a web comprising a pair of rolls through which the web is passed, one roll carrying flexible pointed fingers arranged substantially parallel thereto for impaling the scrap pieces and the other roll carrying resilient material opposed said flexible pointed fingers to contact the scrap pieces so they may be impaled by the pointed fingers. Scrap pieces are impinged on the pointed fingers as the scrap pieces pass between the fingers and resilient material before the nip of the rolls and are pushed outwardly from the surface of the roll by the flexible point finger for removal by a comb, brush or vacuum means.
