Abstract: A document handling apparatus in which sheets are automatically moved in sequence into a registered position on a work surface and then moved out of that position to make way for the next sheet is disclosed. The apparatus includes a document driving belt extending across a surface between first and second edges thereof, a reversible drive for selectively driving the belt in one direction towards the second surface edge and in the opposite direction, a pair of document driving rotary members flanking the belt adjacent the second edge of the surface, and a clutch arrangement for driving said members in said one direction only.

Abstract: This disclosure is directed to a conveying system for transporting documents from the delivery end of one conveyor section to the spaced apart entry end of a receiving conveyor section in a manner wherein the document is stiffened by imparting undulating or corrugated folds therein as it is conveyed so as to facilitate the transfer of the document from one conveyor to the next and thereby permitting at least one or both sides of the document to be checked or read as it is being conveyed from one station to the next at the point of transfer.

Abstract: A method and apparatus for continuously bending or creasing sheet material as the material travels along a path. The invention creases and decurls the material; that is, compensates for a natural tendency to curl in the opposite direction, and serves as a drag on the trailing portion of the sheet material, thereby providing positive sheet control. It is characterized by an air pressure gradient which forces the material into a zone between a pair of parallel, spaced, elongated support surfaces as the material is drawn over the support surfaces.

Abstract: A dispense edge member for detaching a pressure-sensitive label from a backing strip is shaped to impart a transverse curvature to the label during detachment from the backing strip. The curvature increases the rigidity of the label and prevents drooping of the label.

Abstract: A note storage apparatus has a stacking assembly, a push bar assembly movably mounted in the stacker, a coffer assembly for storing the notes, a collector located in the stacker assembly for receiving the notes and the push bar assembly selectively contacting the note and transferring it to the coffer assembly.

Abstract: The self-stripping action of a copy sheet from an imaging suface after transfer in electrostatographic copying is substantially increased by slightly curving the imaging surface transverse their mutual direction of movement to provide a slight corresponding crown in the copy sheet on the imaging surface at the stripping area where the imaging surface is curved away from the path of the copy sheet in their direction of movement. Examples of the imaging surface are a substantially cylindrical photoreceptor surface with a uniform slight continuous crown, or a flexible belt slightly deformed over a crowned support roller.

Abstract: A copier/collator installation wherein the copier's output copy sheets are collated into sets in a multi-bin collator. The collator bins are vertically stacked.Vertical stacking of the electrostatically charged and heated copy sheets, which therefore tend to curl, is enhanced by providing collator bins having electrically nonconductive walls. The bottom sheet-receiving walls are formed to have a generally concave cross section, facing upward. Considering the direction of sheet movement, this concave surface extends generally transverse the sheet movement. Pivoted and biased paper stabilizing wires hold down the leading portion of the sheet stack in the bin, and also absorbs the sheet's kinetic energy as the sheet enters the bin. A flexible, electrically nonconductive plastic flap, at the bin's entrance or mouth, holds down the sheet's trailing portion, and also absorbs the sheet's kinetic energy.

Abstract: A transport mechanism is disclosed for driving inked paper emerging from the printing station of a duplicating machine into a stacking station, the transport mechanism employing a first pair of beveled drive rollers and a second pair of rounded rollers biased against the beveled drive rollers by gravity which prevents ink buildup upon the second pair of drive rollers where bleed edge inked paper is being transported through the system.

Abstract: A printing station including an impression cylinder and a plate cylinder is positioned adjacent an air applicator which causes paper emerging from the nip of the cylinders to be pressed against an arcuate portion of the impression cylinder so as to be driven over a paper guide means which forwards the paper to a stacking station. Drive means are also included adjacent the guide means, consisting of a pair of beveled rollers which produce stiffening of the paper to give it rigidity along its length in order to support the paper in cantilever fashion as it passes from the drive means to the stacker. The air applicator is designed to produce some air travel in the direction of motion of the inked paper to assist in driving the paper and drying the ink.

Abstract: A sheet piling machine for stacking metal sheets of material which respond to magnetic force which machine is characterized by an upright supporting frame defining two in-line stacking areas having suitable lift platforms on which sheets are piled, an elongate overhead magnetic sheet conveyor mounted on the supporting frame above the first stacking or piling area, a roller skate conveyor forming an approach to the entrance end of each of the stacking areas and spaced below the overhead conveyor in predetermined, vertical relation so as not to interfere with the entry of sheets to the respective stacking areas, each roller skate conveyor being inclined in the direction of the associated stacking area so as to cause sheets deposited thereon to be advanced by gravity into the associated stacking area, end stop and back stop mechanisms and a side guide mechanism for each of the stacking areas, and electrical control circuits for controlling the operation of the magnetic conveyor and associated mechanisms so as to

Abstract: A document transport including an endless belt driven by a pair of logic controlled servo motors which precisely move a document from a feeding station through a scanning station and into a stacking station. As documents are passed through the scanning station, images of the characters thereon are projected by a scanner onto a single columnar retina. The scanner includes a single shaft which is repetitively rotated through a preselected arc by a logic controlled servo motor synchronized with the transport control system. An illumination mirror is mounted on one end of the shaft and an image mirror is mounted on the other so that illumination from a lamp is scanned across the characters to be read while the illuminated images are reflected from the image mirror onto the retina.

Abstract: The printed sheet guide mechanism in an offset printing press comprises a stay provided parallel to a delivery roller which is in frictional contact with the eject rollers to rotate therewith, and a pair of guide members each of which has a slanted or curved guide flap. Each of the guide members is secured to the stay so that they are adjustable in their lateral movement, and is also so adapted as to hold at its both edges the printed sheet delivered out passing between the eject rollers and delivery rollers. The guide flap provided in each guide member is designed to bend or curve both edges of the printed sheet to give stiffness thereto.
