Optional Tool Pairs Alternatively Operative Patents (Class 83/479)
  • Patent number: 6637997
    Abstract: A capstan for handling slitting tools comprises a base, a pivoting frame, an outer frame and a plurality of shafts. The pivoting frame is supported by the base for pivotal movement about an axis. The outer frame is supported by the rotating frame for translational movement along the axis. The plurality of shafts extends from the outer frame transversely to the axis. The capstan preferably further includes an axial actuator for translating the outer frame relative to the pivoting frame along the axis. This permits an attendant to raise or lower the outer frame, and, hence, raise or lower the shafts. By thus raising or lowering the shafts, the attendant can adjust the height of the shafts to a comfortable level for loading or unloading knives and spacers without excessive lifting or bending. An optional pusher serves to automatically slide the tools between the capstan and the slitter machine.

  • Patent number: 6138544
    Abstract: A rotary die-cutter having a planetary configuration for die-cutting paper products such as corrugated and solid-fiber paper board includes a frame in which is mounted a rotatable turret assembly. Rotatably attached to the turret assembly is a first die-cutting cylinder, a second die-cutting cylinder, and an anvil. Various tools or forms are detachably mounted to the exterior of the first and second die-cutting cylinders to cut, score, or crease paper box packaging materials. Each die-cutting cylinder is either in an operational position or a set-up position depending on the orientation of the turret assembly. In order to change the tools or forms of a die-cutting cylinder, the turret assembly is rotated such that the operational die-cutting cylinder moves to the set-up position, while the die-cutting cylinder in the set-up position simultaneously moves to the operational position.

    Abstract: The present invention describes an apparatus for creasing and cutting an endless web of cardboard. A pair of rollers operates on the web while another pair of rollers is in an inactive position where the tools mounted on the rollers can be moved to new positions. When it is time for different operations to be performed on the web the original rollers working on the web are removed from their working position and the rollers previously in the inactive position are moved to the working position. The rollers now in the working position have had their tools aligned for the new operation while they were in the inactive position. The rollers originally in the working position are now in an inactive position where the tools on these rollers can be aligned for another operation. Each pair of rollers is independently driven to spin independent of the position of the roller.

  • Patent number: 5107695
    Abstract: The apparatus comprises a pair of rotatable devices (9,11) each holding a plurality of metal shaping and/or cutting rollers (17,19;127), the rollers of one device meshing with rollers of the other device to produce specific designs or widths of material. This is made possible by merely selecting suitable rollers of both sets and when production of a specific metallic section or desired widths are terminated, other rollers are selected by rotating the rotatable devices, if another metallic section or widths are desired. When suitable rollers (17,19:127) have been selected they are locked in operating position and the operation is allowed to proceed by feeding metal strip to the machine. When another design or widths are required, the devices are unlocked, a selection is made, and the devices are again locked to produce the new metallic section or widths of material.

  • Patent number: 4887502
    Abstract: A machine for slitting metal sheet has a bridge-type frame provided with upper and lower beams supported on posts. In the space between the two beams are upper and lower powered arbors and also upper and lower storage arbors which align respectively with the upper and lower powered arbors. Each powered arbor supports and turns several knives which are mounted on hubs along those arbors, and these knives when not needed may be moved, along with their hubs, onto the aligned storage arbors. Each knife is captured in a carriage which moves along one of the beams and contains back-up rollers which bear against the knife to prevent its arbor from deflecting under the spreading force exerted by the metal sheet as it is slit. The hubs have a wide stance, and accordingly the knives on them do not acquire a wobble when the hubs are secured on their respective arbors; yet notwithstanding the wide stance, the knives may be brought quite close together.
