  • Patent number: 11584607
    Abstract: A system for collating and stacking long cut retail edge marker strips exiting a roll fed high speed slitter/perforator/cutter apparatus includes a media collation apparatus that facilitates automated collation of the long retail edge marker strips by collecting them off a surface and through the use of a device of graduated stair configuration separately lifting the retail edge markers from the surface for downstream accumulation. Individual bundles of slit retail edge marker strips are moved in a cross-process direction on integrated shelves of the media collection apparatus by a connected pusher. This allows the bundles to be transferred through the cross-process move in separate bundles before being collated at the end of the move when the pusher retracts to drop the bundles onto a receiving platform.

  • Patent number: 11117386
    Abstract: An inlet seal, an outlet seal, and a piston are connected to a shaft. The inlet seal seals an ink inlet of an ink reservoir. The outlet seal seals an ink outlet of the ink reservoir. Also, the piston is within a cylinder. The inlet seal, the outlet seal, and the piston all move with the shaft. A biasing member contacts the piston to bias the piston in a first direction. Pressurized air simultaneously provided to the cylinder and to the ink reservoir biases the piston in a second direction, opposite the first direction, and pressurizes ink within the ink reservoir. Moving the shaft in the first direction does not seal the ink inlet but does seal the ink outlet. Moving the shaft in the second direction seals the ink inlet but does not seal the ink outlet, thus allowing the pressurized ink out from the ink reservoir.

  • Patent number: 10968068
    Abstract: A system for collating and stacking long cut retail edge marker strips exiting a roll fed high speed slitter/perforator/cutter apparatus includes a series of angled and stepped baffles configured to receive the cut retail edge marking strips and allow them to fall into and accumulate in bins formed by each angled baffle and then be removed from each bin consecutively by a pusher acting orthogonally to the bins to move and collate the retail edge markers into a final stack collated to meet a specific store planogram requirement.

  • Patent number: 9126761
    Abstract: A variable guide system for shingling in-store adhesive signage cards that works with the offset moment/trajectory resulting from some shingling systems by employing multiple adjustable hold downs guides. Adjustments to the hold downs guides are made on the fly by an operator using easily accessible and controllable thumb screws. The thumb screws facilitate side to side movement and angle adjustment of each guide individually in order to prevent jamming of the cards while being shingled at the guides.

  • Patent number: 7988150
    Abstract: A machine which transports and processes print media can incorporate a vacuum chamber. The vacuum chamber can be within a print media transport device in order to maintain a print medium at a uniform predetermined distance from a print media processing device, such as an image printing device (e.g., an inkjet printer), an image scanning device, or a spectrophotometer). In one embodiment the vacuum chamber is located within a roller that transports print media past the processing device. In another embodiment the vacuum chamber is located on an opposite side of a belt that transports print media past the processing device. In each of the embodiments the size of the vacuum chamber opening, which defines the vacuum area on the transport device, and also the amount of vacuum pressure may be selectively adjusted depending upon the size and weight, respectively, of the print medium being processed.

  • Patent number: 7954815
    Abstract: A vacuum transport includes a segmented, rigid or solid articulated belt combined with a vacuum plenum in each segment of the belt. Using a rigid segmented belt with a vacuum plenum connected to each segmented belt section eliminates ordinarily encountered drag friction in conventional vacuum transports by reducing the force necessary to move the belt with media thereon while simultaneously improving the motion quality of the move by driving the articulated rigid belt from the top side of the belt in a flat section.

  • Patent number: 5887868
    Abstract: An apparatus for moving a sheet bi-directionally. The apparatus includes a first roller and a second roller. A drive system is associated with the rollers to drive the first roller in a first direction. The drive system is adapted to rotate the second roller simultaneously with the first roller in the same direction as the first roller or in the opposite direction thereto. In addition, the drive system is capable of idling the second roller so as to adjust the timing of the sheet as it moves to subsequent processing stations within a printing machine.
