Patent number: 4358042Abstract: A wire stitcher for binding sets of sheets has a driver for driving a staple through a set and an active clincher. In one form the clincher has a drive for the clincher ears which is actuated by the driver. The drive is by a spring which is loaded during a return motion of the clincher housing at the completion of a stitching operation. In another form the clincher ear drive is effected by a cam. Both forms are capable of accommodating variations in set thickness essentially without affecting the timing of the operation of the clincher ears.Type: GrantFiled: December 21, 1979Date of Patent: November 9, 1982Assignee: Xerox CorporationInventor: Brian R.

-
Patent number: 4335841Abstract: A wire stitcher for binding sheets into sets in which cut lengths of wire are formed into staples about an anvil by a former and the formed staples are driven by a driver. The wire is gripped against the anvil by the driver during forming and the staple is supported with the aid of the anvil during driving. The driver has a two-stage action in which a first stage motion operates to grip the wire against the anvil during forming, the driver motion being arrested during forming, and a second stage motion acts following forming to effect driving. The movement of the driver and the former is effected by a continuous travel of an input lever.Type: GrantFiled: December 21, 1979Date of Patent: June 22, 1982Assignee: Xerox CorporationInventor: Attila A. Fogarasy
-
Patent number: 4334759Abstract: Apparatus for precise center registration of a sheet with respect to a fixed reference line such as the center line in a copier. To accomplish this, a sidewall and an associated sensor move in unison relative to the machine center line. With the sheet registered against the sidewall, the sidewall and the sensor which are maintained equidistant from the machine center line move until the sensor senses the edge of the sheet. The motion is then stopped by a signal from the sensor thereby providing precise center line registered sheets.Type: GrantFiled: April 3, 1980Date of Patent: June 15, 1982Assignee: Xerox CorporationInventor: Don P. Clausing

Patent number: 4328919Abstract: A wire stitcher for binding sets of sheets has a driver for driving a staple through a set and an active clincher for bending over the ends of the staple legs to form clinches. The clincher includes an ear having a first groove in a side edge for catching the end of a driven staple leg and initiating bending of the leg and a second, narrower groove in an end edge, which is contiguous with the groove and aligns the leg and completes the bending thereof. A transition groove portion connects the grooves at the junction of the edges.Type: GrantFiled: December 21, 1979Date of Patent: May 11, 1982Assignee: Xerox CorporationInventors: Brian R. Lawrence, Peter M. Downing
-
Patent number: 4327904Abstract: A method and apparatus for selectively increasing the effective frictional force between a retard member and a feed member by making both the feed member and retard member from conductive elastomers, and providing a source of electrical potential to produce an electrical potential between them. A sensor is located downstream of the retard member that will sense a multi-feed of sheets between the pad and retard member. The sensor effects the production of electrical potential thereby increasing the friction between the two members and causing separation of the multi-feed of sheets. The potential is then removed and the frictional forces returned to the original level.Type: GrantFiled: May 2, 1980Date of Patent: May 4, 1982Assignee: Xerox CorporationInventor: Maurice F. Holmes
-
Patent number: 4320960Abstract: An automatic duplicating system in which computer fanfold documents are fed by an automatic handling apparatus having a tractor and drive control system for advancing the document across the platen of the processor for the system. An arrangement is provided which will shut down the system in the event there is a break in the fanfold material during a reproduction run or the end of the document has been attained during normal operation. Sensing devices are utilized in the path of movement of the document and a circuit is provided to produce a train of pulses in accordance with the movement of the document. The frequency of the train of pulses is compared with a reference frequency to insure proper operation.Type: GrantFiled: September 17, 1979Date of Patent: March 23, 1982Assignee: Xerox CorporationInventors: Joseph W. Ward, Russell G. Schroeder, II
