Anvil Has Motion In Addition To Rotation (i.e., Traveling Anvil) Patents (Class 83/510)
  • Patent number: 6772663
    Abstract: An improved rotary pressure cutting apparatus that cuts, perforates, and scores plies of paper, window materials, label stock, and plastic laminates in conjunction with soft, discontinuous, and/or non-cylindrical anvil surfaces. A light weight, low mass anvil in the form of a metallic sheet is supported in a strike position beneath a rotating blade. The anvil is biased by springs or elastomeric members toward the strike position and moves with the material being cut and the moving cutting blade during a cut. The anvil is returned to the strike position by the biasing member upon completion of the cut.

  • Patent number: 4680083
    Abstract: A revolving base roller and a stationary cutter are mounted on opposite sides of the path of a laminated strip, in order to partially cut the strip from one side at desired cut lines along its length. The laminated strip includes a strip of printed labels on the printed side of which is overlaid a transparent film strip which is disposed toward the stationary cutter as the laminated strip passes along its path. A sensor detects an indication that the labels are properly positioned, and a control circuit receives a signal from the sensor and causes a single rotation of the revolving base roller. As the base roller revolves, it pushes against the opposite side of the laminated strip, causing the film strip to be pushed against the stationary cutter, resulting in the cutting of the film strip along the desired cut line. The stationary cutter may be adjusted to provide a cut of the desired depth.

  • Patent number: 4638702
    Abstract: The disclosed cutting method and apparatus produces a pattern cut in web material by providing a generally conically-shaped rotatable anvil and oppositely disposed knife edge shaped to produce the pattern cut. The axes of symmetry containing the apex of the cone is positioned at an acute angle to the axes about which the cone is rotated. With the web positioned over the knife, the knife is brought into pressure engagement with the anvil thereby piercing the web substantially at a point. Rotation of the anvil effects progressive cutting as the anvil surface traces the cutting edge of the knife.

  • Patent number: 4581008
    Abstract: An apparatus which produces a precisely shaped and positioned perforated line in a blank for a parallelepipedic package has a blade and a roller for pressing the blank against the blade. The blade is stationary relative to the packaging blank and provides a perforated line which does not penetrate the inner layer of the packaging material. The roller is mounted on a connecting bar which is linked to a reciprocating drive. The roller moves in a guide which positions the roller relative to the blade during each stroke of the reciprocating drive.

  • Patent number: 4480507
    Abstract: A cutting die assembly for cigar wrappers is manufactured by rigidly interconnecting a knife blade unit and a die assembly on a common carrier. The die assembly has an opening of particular shape bounded by a generally planar margin over which tobacco leaf may be draped. The knife unit is formed by shaping knife blade strip into a closed form to fit just inside the shaped margin of the die assembly with the knife edge just above same. The shaped knife blade strip is filled with a filling body interiorally to a height substantially below the cutting edge and is internally rigidified thereby. A suction air chamber is defined by the rigidly interconnected units and is bounded by the common carrier, the die assembly and the outer surface of the knife blade strip. Openings are provided through the margin of the die assembly to the suction air chamber to hold the draped tobacco leaf and stretch it over the knife edge.

  • Patent number: 4339974
    Abstract: There is provided an improvement in an apparatus for cutting a profile of a selected shape from a natural sheet material at a given location, which apparatus comprises a cutting platen having an upper generally flat cutting surface and a lower generally flat support surface. The platen is movable to the desired position relative to a cutter which moves along an axis downwardly against the cutting surface to cut the preselected shape from the natural material. In accordance with the improvement, there is provided a fixed anvil having a flat force reaction surface parallel to and facing the supporting surface of the platen so that the cutting action is against the anvil. The anvil can also form the structure for supporting the platen as it is moved into the cutting position.

  • Patent number: 4331055
    Abstract: In an apparatus for cutting portions such as labels or tickets from a continuously moving web, the web is passed between a blade and a co-operating support member. As the web moves past the blade, the blade is displaced during the cutting operation in the same direction as the web and synchronously therewith, but over a shorter distance than the length of the portion to be cut out. The blade is then disengaged from the web and returned to its initial starting position. The support member may also be displaced in the opposite direction to the movement of the web and blade during the cutting operation.

  • Patent number: 4014257
    Abstract: Apparatus for supporting a die plate having indicia formed thereon by a raised rib and for forcing a tape into engagement with the raised rib to cut indicia from said tape corresponding to the indicia on the die. The apparatus utilizes a flat platen supporting one side of the die, a roller mounted on a movable frame and spring biased toward the die plate. A tape is guided across the surface of the die plate at an oblique angle to the direction of movement of the roller such that to cut alphabetic or numerical indicia the cutting is generally taking place at spaced points on the surface of the roller and generally no cuts are made along a line defining a portion of the indicia. The apparatus is cycled by an operating lever to move the roller across the surface of the tape under sufficient spring pressure to afford the cutting operation and then the roller is retracted as the operating handle is returned to the normal position.
