  • Patent number: 6948224
    Abstract: An automatic stapling apparatus and method is disclosed which may have a stapling mechanism moved by a stapler engaging mechanism into a stapling position in relation to a stack of sheets to be stapled, inserted through a stack insertion opening, and adapted to staple a stack of sheets up to a maximum thickness, and may comprise: a sheet stack thickness gauging apparatus adapted to move into a sheet stack thickness gauging position prior to the stapling mechanism being moved by the stapler engaging mechanism into the stapling position; the sheet stack thickness gauging apparatus being further adapted to engage any object within the insertion opening in position to be engaged by the stapler which is of a thickness greater than or equal to a pre-selected thickness; and, a safety disconnect apparatus adapted to prevent the operation of the stapler in the event that the sheet stack thickness gauging apparatus engages an object in the insertion opening in position to be engaged by the stapler which is of a thickne

  • Patent number: 6450492
    Abstract: Apparatus is provided for receiving and assembling sheets in a binding station at which thermal binding strips are automatically supplied to the side edges of the assembled sets, the sheet receiving trays at the binding station are laterally moved apart to allow a set of assembled bound or unbound sheets to gravitate to a stapling station at which an assembled set of sheets may be stapled together, and the trays forming the stapling station are moved laterally apart to allow the stapled set to gravitate to a stacker tray which is allowed to move downwardly as progressive sets are deposited on the stacker tray and the stacker tray is moved upwardly to a set receiving position following removal of finished sets.

  • Patent number: 6328299
    Abstract: A moving shelf set finishing mailbox has a plurality of trays vertically movable by rotatable cams to opposite sides of a sheet inlet location from which sheets are supplied serially from a copier or printer, the sheets being supported at their trailing edge on a shelf integral with the tray and their forward ends being supported by the tray and by any underlying sheets. The trays are sequentially or randomly moved by the rotary cams and when randomly moved, the apparatus functions as a mailbox in which the sheets are stapled while the trailing edges are supported on the shelf and the sets are moved by pushers from the shelf by pushers so that the trailing end of the sets are finally supported by the tray.

  • Patent number: 6230599
    Abstract: A punch is disclosed in which cams at the opposite ends of a rotary shaft move a spring returned mechanism so as to apply a force to a number of punches which are aligned across a pressure plate and movable towards a die plate for punching sheets of paper fed between the pressure plate and the die plate upon each revolution of the shaft and the cams, the punches being formed and supported by the pressure plate so as to progressively enter the sheet of paper to allow for a reduction in the motor force required for performing a punching operation.

  • Patent number: 5845901
    Abstract: A moving bin sorter of the type in which the trays are individually and collectively moved vertically relative to a sheet inlet location and opened to provide an enlarged sheet entry space for receiving the sheets, has cams and counterbalancing springs to lift the trays supported in a support structure which maintains the trays in parallel relation, thereby maintaining equal spacing for printed sheet storage along the complete effective length of the trays. In one form, the support structure is a unit moved upwardly by the springs, and in another form, the support structure has a member integrated with the tray housing and a cooperative member moved upwardly by the springs, the trays being supported at all times in parallel relation.

  • Patent number: 5713566
    Abstract: A moving bin sorter of the type in which the trays are individually and collectively moved vertically relative to a sheet inlet location and opened to provide an enlarged sheet entry space for receiving the sheets, has trays displaced in a manner which controls and allows them to move parallel to each other at all times. Alignment and registration units have steel rule type members oppositely extensible into the enlarged sheet entry space with pads on the ends thereof conforming in shape to the enlarged sheet entry space for aligning the edges of various sizes of sheets and moving sets of sheets laterally of the trays to a stapler and returning the stapled sets towards the center of the trays.

  • Patent number: 5618035
    Abstract: A self-contained offset stacker tray assembly is operable in conjunction with the sheet output of a host printer or copier to receive sheets from the host machine and deposit the sheets in offset sets. The assembly includes a supporting base for a frame structure reciprocable transversely of the direction of sheet infeed from the host and containing a receiver tray, infeed rolls to supply sheets to the trays, a rotary cam mechanism for shifting the frame assembly relative to the output from the host machine and the receiver tray being vertically movable within the frame structure and biased upwardly by counter balancing springs to be moved downwardly as the weight of the sheets in the tray increases.

  • Patent number: 5593153
    Abstract: A moving tray sorter has a set of trays configured to extend upwardly from a horizontal plane at the point of sheet entry and each tray has progressively from the sheet inlet end a back stop against which the trailing edges of sheet are aligned, a horizontally extended section and an upwardly inclined section of a substantial angle from the horizontal providing trays which are short, which occupy a relatively small area or footprint and which support sheets of relatively large size and overhang without droop of the sheets at the outer ends.
