Abstract: In an insertion machine a track 20 moves groups of items past feed station 31, 32, 33, 34, 35, 36, 37, 38, 39, during respective machine cycles. The feed stations selectively feed items onto the tracks 20 for inclusion with a group of items and eventual stuffing into an envelope. A master control item 46 fed from station 31 for each group has indicia 50 thereon which provides an indication from which of the feed stations items can be fed. In order for data processor 102 to calculate the amount of postage appropriate for the stuffed envelope, an operator uses a keyboard and display 110 to input predetermined per item weight values for items held at select stations. A data processor 102 uses the predetermined values indicative of the per item weight of items held in the stations to obtain a calculated total weight for each group of items.

Abstract: A Sheet Feeding System (10) having a reciprocating vacuum shuttle plate (52) includes a knife gate (112) and high-friction rollers 118 and 120 position between the knife gate and an additional conveyor formed by a driven feed roller 94 and an idler feed roller 96. The high-friction rollers form a singulator gap (188) with shoulders 184 of a vacuum-groove (186) on a sheet-engaging surface of the reciprocating shuttle plate. The sheet feeding system includes a transition tray (14) downstream of the additional conveyor for providing a transition to clamps of an endless chain (178). The transition tray comprises an endless conveyor belt (156) with a floating feed roller (160) biased thereagainst. The position of the floating feed roller can be adjusted so as to space it approximately a sheet length from a stationary clamp (176) on the endless chain.

Abstract: An apparatus (570) for forming a window in which printed characters on an item such as an envelope can be read. The apparatus (570) comprises a base member (572) fastened to a planar horizontal surface (508) and positionable intermediate a reader device (50) and an on-edge envelope. The base member (572) has an elongated vertical slot provided (576) therein. A slide member (584) has a bottom edge which includes a dimpled portion. The dimpled portion of the slide member (584) fits into the elongated vertical slot (576) of the base member (572). The base member (572) carries a block (578) which accommodates a screw (582) for selectively adjusting the position of the bottom edge of the slide member (584) relative to the base member (572). A bottom edge of the slide member (584) and a portion of the elongated vertical slot (576) below the bottom edge of the slide member (584) form a read window through which characters are readable.

Abstract: An inserter with collation tracking comprises a programmable computer, means for tracking handled items including individual tracking and collation tracking, sensing means for sensing individual items in different locations, as well as for sensing defective, multiple or missing items, corrective action means, and, means for updating tracking information in correspondence with corrective action taken. The inserter performs corrective action in the form of the rejection and diversion of defective items. Further, the inserter provides for complementarily associating envelopes with particular inserts intended for insertion thereinto, for collation tracking of such complementarily-associated items, and for the diversion of such associated items if at least one of the associated items has been stigmatized as defective.

Abstract: An envelope flap opener comprises a revolving gripper drum for conveying envelopes thereupon in flap-up orientation with flap edge trailing and a revolving rotor disposed vicinally to the gripper drum, the rotor having at least one sucker cup extending from its periphery. Vacuum is valved to the sucker cup at a time when an envelope is conveyed upon the gripper drum past the rotor, the sucker cup grabs and opens the envelope flap, and subsequently the flap is released. Prior to release of the flap, a plow device intercepts the flap and further unfolds it. The plow device includes a photo-sensor for checking of proper flap opening and for detecting missing envelopes.

Abstract: A sheet material feeder for high speed singulating and seriatim feeding of sheet material articles from the bottom of a stack disposed in a hopper comprises apparatus for feeding sheets from the stack and a restrainer device for restraining all but the lowermorst sheet from being fed from the hopper by virture of transversely corrugating the sheet while it is fed from the hopper and passed through the restrainer.

Abstract: An improved document feeder for feeding a predetermined number of singulated checks in seriatim for accumulation into a check stack package, for delivering the package to further handling device, and for realigning the checks therein while the package is being delivered. The feeder comprises a singulator; a feeder section that feeds the singulated checks via a spider wheel to an accumulator bin for accumulation into a check stack package; and reciprocating kicker arms for realigning the accumulated check stack package and for delivering the check stack package to further handling devices. The reciprocating kicker arms the accumulated check stack package by engaging trailing edges of the checks in the check stack package and kicking the package into engagement between driven nip wheels. The kicker arms and the driven nip wheels deliver the check stack package.

Abstract: A speed optimization circuit (140) is employed by an insertion machine to result in a greater actual throughput of successfully enveloped sets of documents. The speed optimization circuit (140) includes a microcontroller (142) which determines whether the machine cycling speed should be changed and which generates a signal for application to a speed adjustment servomechanism (136) for automatically changing the machine cycling speed in accordance with the determination.

Abstract: A rotary flap closer for closing envelope flaps during processing of mailable articles comprises a rotary member having a revolving arm and an elastically resilient member mounted along the arm and revolving therewith. At least a portion of the elastically-resilient member extends from the arm toward a conveyor surface on which envelopes are conveyed to and through the rotary flap closer, whereby the elastically-resilient member slidingly engages open flaps, deflects the flaps onto the envelope bodies, and thereby closes the envelopes. In one embodiment the elastically-resilient member is a brush.

Abstract: An in-line rotary inserter device comprises an envelope feed station (30) and insert feeding modules (20,22,24,26), an inserting station (32), a sealing and stacking assembly (38,40,42), and various diverters (33,36,56). The envelope feed station (30) withdraws envelopes from a hopper-held envelope stack )66,94) and conveys them to the inserting station (32). Each insert feeding module comprises a hopper-held insert stack disposed above, along, and in line with an insert conveyor (34). The conveyor, along its track, carries inserts dispensed from the hopper-held insert stacks to the inserting station (32). Diverter stations for diversion of envelopes and inserts in various locations along their feed paths are provided for normal operational purposes and for rectification of sensed fault conditions. Subsequently to inserting, insert-filled envelopes are conveyed from the inserting station (32), are sealed, turned, stacked, and processed through operations that are customary in preparation of mailable items.

Abstract: A sheet separator device for side-by-side parallel sheet articles being handled and conveyed in sheet handling machines comprises first and second endless belt arrangements for conveying sheet articles in nips between belts, wherein first and second belt arrangements are divergently disposed in relationship to one another so that sheet articles entering respectively thereinto in a common plane in side-by-side parallel relationship are conveyed thereby along respective divergent paths. Sheet articles exiting from divergent first and second endless belt arrangements, respectively, are farther conveyed in a common plane along side-by-side parallel paths which are separated by a larger distance than the original distance between sheet articles entering the first and second endless belt arrangements.
