Abstract: A sheet post processing machine has a first shelf for assembling a number of sheets without causing any inhibition to the speed of sheet delivery from a host printer or copier, and the assembled sheets are dumped from the first shelf to a second shelf at which the sheets are collected in sets, jogged into edge alignment, stapled at the corners or along an edge, the sets are offset from one another, and finally, dumped from the second shelf onto a stacker tray.

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.

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.

Abstract: A stapling stacker has a sheet infeed, a pivoted shelf on which the trailing ends of sheets are assembled with the leading ends supported by previously stacked sets, the sets are side edge aligned, stapled into sets and offset with respect to previously stapled sets, and the shelf then is operated to dump the trailing ends onto previously stapled sets of sheets on the stacker.

Abstract: A printed sheet transporting apparatus has a sheet inlet adjustable to selected heights and including an optional inverter for incoming sheets, a sheet feed path leading to selected positions in which a deflector may be adjustably positioned for deflecting sheets to various receivers for the sheets which are mounted on the apparatus at a plurality of vertically spaced sheet receiving positions.

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.

Abstract: A sorter mailbox has a sheet transport for moving sheets through a feed path to a set or sets of vertically spaced receiver trays having sheet deflecting gates which are actuated so as to sowing toward or into an open sheet deflecting position so as to contact with light spring pressure a sheet moving through the sheet feed path but to open to deflect the sheet into a selected tray from the sheet feed path.

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.

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.

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.

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.

Abstract: A sheet receiver has multiple trays for receiving printed sheets from a host copier or printer to collate or receive the printed sets or jobs made up of sequential sheets fed to the trays by an infeed roll driven at variable speeds depending upon the measured length of the sheets as they are moved past a sheet sensor by the infeed roll.
