A web separator is provided that cuts a web at predetermined separation locations. Downstream of the cutting, the web is folded at predetermined fold locations. A continuously swinging director, downstream of the folding, guides advancing sections of web to opposing fold edges of a supported zig-zag stack. The web is driven into the continuously swinging director by a driving member. The driving member is deactivated selectively by a clutch, while other elements of the separator continue to operate. A central drive motor may be interconnected with each of the drive member, swinging director, folding and support elements. Fold and separation locations may be determined by a bar code detector and selectively operable upper and lower conveyor belts may be disposed below the supported zig-zag stack.

Apparatus for separating folded web

A system for conveying folded web and forming discrete stacks of folded web comprising a conveyor (54) that receives a stack (52) of folded output web from a web folder and separator (32). The conveyor (54) drives the web from an upstream end, adjacent the web folder and separator (32), to a downstream end. A supporting surface (206) selectively supports the web remote from and off the conveyor (54). At selected times, the stack (52) is moved by the supporting surface (206) into communication with the folder and separator (32) so that it can be conveyed downstream. An elevator platform (86) can be located at the downstream location for receiving successive stacks thereon. The elevator platform (86) can include a drive that enables it to rotate so that successive stacks are deposited on the elevator platform (86) in a rotationally offset orientation relative to each other.

On decrit un procede et un dispositif d'alteration de codes a bares sur des articles, un dispositif d'emballage d'articles, et un dispositif de transport des articles d'un dispositif d'orientation a un dispositif d'emballage. Describes a process and a code altering device bares on articles, a packaging device for articles, and a device for transporting the items of an orientation device to a packing device. Chacun des articles possede un code a barres place par le dispositif d'orientation face a un dispositif de marquage. Each of the articles has a barcode placed by the orientation device facing a marking device. Le dispositif d'orientation peut etre lineaire ou de type chariot a plateau tournant. The orientation device may be linear or type truck turntable. Le dispositif de marquage est soit un jet d'encre, soit un laser qui fera une marque dans le code a barres de chaque article. The marking device is either an ink jet or a laser which makes a mark in the bar code of each article. Le dispositif d'emballage placera une pluralite d'articles dans un receptacle a extremites ouvertes tel qu'un carton. The packaging device will place a plurality of articles in an open-ended receptacle such as a carton. Certains de ces codes a barres seront visibles par l'extremite ouverte du receptacle. Some of the barcode will be visible through the open end of the receptacle. A cause de la marque faite dans ces codes a barres, ceux-ci, en exposition, ne pourront plus etre lus par un lecteur optique. Because of the mark made in these barcodes, thereof, in exposure, can no longer be read by an optical reader.

A method and device for corrupting bar codes on articles prior to packing.

A device for obliterating printed information on a sheet utilizes an information concealing printing unit for printing an information concealing pattern over a surface of a sheet carrying printed information. On printing the information concealing pattern over the surface of the sheet carrying the printed information, the printed information becomes unreadable. Various types of printing devices may be used and the printed information which is obliterated may be first recorded in electronic format for later retrieval.

Sheet printd information obliterating device

Flexible composite material is provided upon which a facsimile message containing both confidential and nonconfidential information can be recorded. In general, the composite material comprises a recording layer and a cover layer. The recording layer has a predetermined width and a longitudinal extent which varies in length consistent with the length of the recorded message. The cover layer is disposed over the recording layer to define a confidential message recording area and at least one non-confidential message recording area. Both message recording areas extend along the longitudinal extent of the recording layer. The cover layer permits recording upon the non-confidential area and confidential area, while concealing the confidential message prior to the cover's removal. Preferably, a releasable adhesive layer is disposed over the confidential message area, so as to releasably secure the cover layer to the recording layer without adversely affecting the integrity or functioning of the confidential recording area. In practice, the adhesive layer is formed as spaced-apart strips and includes perforation lines formed in the cover layer. These perforation lines provide a visual indication that the cover layer had been removed or tampered with. According to another aspect of the present invention there is provided a method of delivering a hard copy of a confidential message. The method involves utilization of a facsimile data communication system including at least one transmitter and at least one receiver operably associated with a recording means capable of utilizing the flexible composite of the present invention.

In a method of rendering subject matter which is printed on one surface of a computer paper sheet unintelligible, an alpha-numeric interference pattern is printed over substantially the entire printing area of the surface of the sheet carrying the printed subject matter, the density of the interference pattern being sufficient to render the printed subject matter unintelligible. One particular use of the method is in the overprinting of computer print-out paper having printed information on one surface, so that the paper may be reused by printing on its opposite surface without permitting access to the information on the first-printed surface. A machine is disclosed for this application of the method.

In a method of and apparatus for rendering subject matter which is printed on one surface of a paper sheet (11a) unintelligible, an alpha-numeric interference pattern (Fig. 7) is printed over substantially the entire printing area of the surface of the sheet (11a) carrying the printed subject matter, the density of the interference pattern (Fig. 7) being sufficient to render the printed subject matter unintelligible. One particular use of the method is in the overprinting of computer print-out paper having printed information on one surface, so that the paper may be reused by printing on its opposite surface without permitting access to the information on the first-printed surface. A machine (10) is disclosed for this application of the method.
