Abstract: A sheet inserter inserts special insert sheets into a continuous stream of sheets by overlaying the insert sheets with a corresponding sheet in the continuous stream of sheets. The insert sheet overlaying the corresponding sheet in the continuous stream of sheets is then conveyed with the corresponding sheet to a final destination where the sheets can be compiled into a stack. The sheet inserter can be contained in a module which is removably attachable to a document finishing apparatus so as to insert the special insert sheets into the stream of sheets that are output from the document producing apparatus. When the document producing apparatus is associated with a finishing device such as a booklet maker, which compiles and stitches multiple copies of a booklet, the sheet inserter inserts one or more special insert sheets at the appropriate location(s) for each booklet as the sheets are entering the assembly station of the booklet maker.

Abstract: Embedded intelligence in the form of machine readable indicia printed on at least some of the sheets of a document is used by a document integrating device to control a feeding operation performed by the document integrating device. Regular sheets located in the document immediately preceding the location of an insert sheet are output with machine readable information indicative of the subsequent location in the document of an insert sheet. These regular sheets are then supplied to a document integrater (either in a stack or as they are output from an imaging device). A first scanner in the document integrater scans the regular sheets as they are fed from an inlet (having, for example, a regular sheet feeder unit). When a regular sheet located in the document immediately prior to an insert sheet is fed from the inlet, the machine readable information indicative of the subsequent insert sheet is read by the first scanner.

Abstract: A finishing apparatus to be used with computer driven or IOT type printers that deliver copy sheets 1-N face-down includes an inverted stapler. A copy sheet set is brought into contact with the clamping surface of a fixed head of the stapler. After the copy sheet set is secured against the clamping surface, a staple is driven therethrough.

Abstract: An electrostatographic printing system is disclosed as having a sheet registration mechanism comprising rotating fingers arranged to intercept the leading edges of copy sheets and to register the same as they are being processed. The fingers are mounted in flexible joints so that they may be flexed out of operation in the event that extra large copy sheets are being processed.

Abstract: A flash exposure, full frame electrostatographic printing system is disclosed as having a document support drum and an optical arrangement for scanning a document for exposing the same to a moving photoreceptor belt. The optical arrangements for flash exposure and scanning have most of their respective parts in common. A mirror is incorporated into the optical arrangement for scanning and is movable into and out of the optical path thereof.

Abstract: An envelope construction for use in a copy sheet feeding apparatus of a copying machine. The envelope having panels which, before closure and sealing, have only two overlapping layers of material and straight side edges which are equal to or greater than the distance the envelopes travel while being guided in the sheet feeding apparatus and before entering the transport system for the copying machine.

Abstract: An apparatus in which a plurality of sheets are adhesively bound together to form a booklet thereof. A glue applicator blade is reciprocated into and out of contact with a marginal region of sheets advanced thereto in seriatim. The glue applicator blade forms a line of adhesive on the marginal region of each sheet. The sheets are overlayed and pressed together to form a bound booklet thereof.
