  • Patent number: 6520080
    Abstract: A system and method for detecting and diverting sections of web having splices on a continuous web is provided. A splice detector is located adjacent a source of continuous web, typically a roll. The movement of the web from the roll is tracked, and the relative location of the splice within the web stream is noted by a controller. Downstream, a web utilization device is provided with a movement detector also connected to the controller. Movement of the splice-containing section through utilization device is tracked so that the splice-containing section is not processed by the utilization device, or is reprocessed on a non-splice-containing section. A cutter is also provided with a movement detector, also connected to the controller. Movement of the web from the utilization device to the cutter is tracked and the section containing the web is cut. A diversion mechanism can be used to remove the cut section of web containing the splice so that it does not appear in the final stream of finished cut sheets.

  • Patent number: 6460844
    Abstract: An apparatus for selectively streaming and merging side-by-side sheets is provided. In general, sheets enter in a side-by-side orientation onto an input feed surface and are directed selectively upwardly or downwardly onto overlying upper and lower feed surfaces by a diverter assembly having two diverter sides. The diverter sides can be independently moved to direct sheets upwardly or downwardly. The upper feed surface and lower feed surface have opposing edge guides. The upper feed surface and lower feed surface can be moved with respect to each other so that the edge guides are placed one sheet width apart or more than two sheet widths apart. By orienting the two diverter halves, and setting the desired distance between the upper and lower edge guides, sheets can pass along each of the upper and lower surfaces in a side-by-side streamed or over-lapping merge orientation.

  • Patent number: 6450383
    Abstract: A system and method for utilizing web that is free of tractor pin feed holes comprises the driving of the web along a predetermined path within the utilization device. A web guide is provided in an upstream location from a utilization device element. The guide engages width-wise edges of the web and forms the web into a trough to stiffen the web. A drive roller and a follower roller impinge upon opposing sides of the web and rotate to drive the web through the guide. The drive roller is located adjacent to the guide according to a preferred embodiment. A registration controller is utilized to synchronize the movement of the web with the operation of the utilization device element. The controller includes a drive controller that controls the speed of either the drive roller or the utilization device element to maintain the web and the utilization device element in appropriate synchronization.

  • Patent number: 6357349
    Abstract: A device for feeding web material to a printer that is adapted to accept web from an external roll, adequately align the web with the printer and properly tension the web as it passes through the printer. The infeed device includes a pair of parallel guide rods spaced sufficiently apart to allow passage of the web there between. A pair of edge guides, attached to the parallel guide rods define the web path there through. A spring-loaded pressure pad acts in combination with a smooth metal shoe to tension the web. Further tension is applied to the web as it passes a curved smooth metal surface, just prior to entering the printer. The infeed device allows a wide variety of web materials and web thicknesses to be tensioned and fed into the printer.

  • Patent number: 6305857
    Abstract: A system and method for utilizing a continuous pinless web that is free of tractor pin feed holes within a utilization device that is originally adapted to feed web having tractor pin feed hole strips along its widthwise edges is provided. The utilization device can comprise an IBM high-volume laser printer having an image transfer drum synchronized to a pair of tractor pin feed drive units. A drive roller is operatively connected to the lower pin feed unit according to a preferred embodiment. A registration controller is utilized to synchronize the movement of the web with the operation of the utilization device element using a differential and a separate registration motor. The image transfer drum and drive roller are each synchronized to a central drive motor that generates pulses via an encoder. The pulses track the movement of the image transfer drum. A mark sensor reads marks on the web to synchronize actual movement of the web with the image transfer drum using the registration motor.

  • Patent number: 6286744
    Abstract: The invention is a stapler and staple guide assembly for same. The stapler provides automated stapling for stacks of sheet material regardless of stack thickness. In a first embodiment two staple guides load individual sheets or small stacks of sheets onto a staple with the staple supported in a base. The staple is then cut to an appropriate height and cinched. In another embodiment, numerous split guides may be cascaded to increase staple loading speed. Other improvements to a stapling process include dimpling sheets of material and/or pre-drilling sheets of material to simplify loading sheets onto a staple.

  • Patent number: 6243617
    Abstract: A system and method for incorporating, in the production of a continuous stream of images, by an image transfer device upon a moving web, post-production operations upon the web at various locations. Locations of a web, having a plurality of images placed thereon, output from an image transfer device are tracked. Specific operations at various locations upon the web are performed by a post-production device as the web passes through it. The web is directed from the image transfer device to the post-production device. In response to the tracking of locations upon the web, the point when a location has entered the post-production device is determined. In response to this determination, the post-production device is commanded to perform its specific operation at a connect location.

  • Patent number: 6113344
    Abstract: A method and apparatus for sorting books of sheets in which individual books are generated in succession is provided. This process entails the stacking of cut sheets that form a completed book in an offset arrangement relative to adjacent books. Each offset stacked book is removed from the other books by applying a lifting force between the lowest book in the stack and the next book in the stack while the lowest book in the stack is allowed to bend away from the next highest book in the stack. The bend forms a space, tunnel or separator entrance opportunity into which a projection or other separator structure is directed. The lowest book is lowered onto a conveyor and moved away from the stack. The process continues for each successive next-highest book in the stack. A support mechanism is provided to maintain the lowest book at a selected elevation as the projection moves inwardly. The support moves away concurrently to deposit the lowest book on the conveyor.
