Appl. No.:

10/248564

Inventors:

Joseph J. Ferrara - Webster NY, US
Richard A. Van Dongen - Newark NY, US

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B31B 1/14
B41F 13/58

US Classification:

493361, 493353, 493356, 493360, 270 503, 399385

Abstract:

Sheets can be manipulated for punching, perforating and/or folding. The systems and methods according to this invention allow sheets to be punched and/or perforated in various configurations. The systems and methods according to this invention allow sheets to be folded in various forms and/or configurations. Sheets can be inverted to ensure proper orientation. The systems and methods according to this invention allow the number and/and or locations of punches and/or perforations and the type and/or length of folds to be controlled on a sheet-by-sheet basis. The systems and methods according to this invention allow the sheet preparation module to be optionally configured within the photocopying system depending on the needs and flexibility of the finishing requirements of the operator. The modularity of the sheet preparation module design as a “plug and play” unit enables greater functionality for the manipulation of sheets.

International Classification:

B65H 5/00

US Classification:

271264, 271275, 271307, 271311, 271312

Abstract:

A paper or sheet buffering system is provided which avoids having to shut down the entire system when the paper path or transport is overloaded. A rotating disk having an attached collection and dispensing finger(s) is used to pull excess sheets off the transport and hold them until it is suitable to dispense them back on to the transport.

International Classification:

B41J 11/00

US Classification:

400579, 400578

Abstract:

According to aspects described herein, there is disclosed an apparatus for de-skewing substrate media in a printing system. The apparatus including and idler roller and a drive roller. The idler roller for engaging substrate media. The drive roller cooperating with the idler roller to form a nip assembly for moving the substrate media in a process direction. The drive roller rotatably supported on a shaft axis by a first bearing element and a second bearing element. The first and second bearing elements disposed remote from one another along the shaft axis. The shaft axis pivotally supported at the first bearing element for aligning the shaft axis with a substrate media skew. The shaft axis configured to pivot about a pivot axis perpendicular to the shaft axis and extending through the first bearing element.

International Classification:

G03G 15/00
B65H 7/02

US Classification:

399395, 271278

Abstract:

According to aspects described herein, there is disclosed an apparatus and method for de-skewing substrate media in a printing system. The apparatus includes at least one sensor for measuring skew of the substrate media being transferred relative to a process direction, and a nip assembly for moving the substrate media in the process direction. The nip assembly includes a nip having a drive roller and an idler roller for engaging the substrate media. The nip assembly is pivotal from a default position an amount responsive to the measured media skew. The drive roller is selectively stopped to permit a leading edge of the substrate media to engage the stopped drive roller.

Abstract:

According to aspects described herein, there is disclosed an apparatus for de-skewing substrate media in a printing system. The apparatus includes at least one sensor for measuring skew of the substrate media being transferred relative to a process direction. The apparatus also includes a nip assembly for moving the substrate media in the process direction. The nip assembly includes a drive roller and an idler roller for engaging the substrate media. The drive roller is rotatably supported on a shaft axis, with the shaft axis being pivotally supported substantially at one end thereof for aligning the shaft axis with the measured substrate media skew. The shaft axis pivots about a pivot axis perpendicular to the shaft axis.

Assignee:

XEROX CORPORATION - Norwalk CT

International Classification:

G03G 15/00
B65H 7/06
B65H 7/08
B65H 7/10

US Classification:

399388, 271228

Abstract:

This invention uses a paper registration device with a paper transport and a stalled roll together with an upstream and downstream CIS to enable paper skew measurements. The upstream CIS is positioned on a paper sheet transport between a beginning pre-registration nip and a buckle control sensor. A second downstream CIS is aligned with the first upstream CIS to provide skew measurement on the same side of a paper sheet. An advantage of this registration device is that it simultaneously corrects registration in a process direction, a cross process direction and corrects skew angle.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B31B 100

US Classification:

493 23

Abstract:

An improved sheet folder for flimsy printed sheets with an automatic fold position correction system. The folder may have an input sheet feeder, a fold chute with a chute entrance, reversible sheet feeding rollers in the fold chute adjacent to the chute entrance, fold rollers, a folded sheets output path, and a sensor system for sensing the length of folded sheets in the folded sheets output path. A sheet to be folded is may be partially fed into the fold chute, engaged by the reversible rollers, and fed thereby further into the chute by a selected distance corresponding to a desired folding position along the sheet. Then, the reversible rollers are stopped at a selected sheet stopping position and reversed to feed the sheet into the fold rollers, cooperatively with the input sheet feeder. The fold rollers feed the folded sheet into the folded sheets output path. The sensor system there provides a control signal modifying the selected stopping position of the reversible rollers, to provide a fold position correction system.

International Classification:

B65H 3905

US Classification:

270 5801

Abstract:

In an on-line printed sheets output handling system for the sequential output by a reproduction system, in which the printed sheets are registered in neatly superposed sets which are optionally fastened together by a finishing system, which is laterally repositionable to provide variable set finishing; a lateral registration system for said printed sheets output is repositionable with said finishing system, and has a sheet registration member engaging and laterally registering the printed sheets to selectable variable lateral sheet registration positions by the finisher lateral movement repositioning system rather than a separate lateral repositioning system, with a registration disengagement system for moving the sheet registration member out of registration engagement with the sheets after a set of sheets has been laterally compiled and before the finishing system is laterally repositioned. The finishing system may comprise two staplers, one of which is fixed, and the other of which is laterally repositionable and carries the sheet registration member of the lateral registration system. This system may be integral a disk inverter stacker system.
