An apparatus for registering sheet material while being conveyed along a feed path including: (i) a conveyance deck for conveying sheet material along a support surface, (ii) a registration member defining an abutment surface operative to align an edge of the sheet material as the sheet material is conveyed along the support surface of the conveyance deck, and (iii) a drive mechanism disposed adjacent to the registration member and along the conveyance deck. The drive mechanism includes a flexible belt disposed about and supported by at least two rolling elements, and a means for driving the flexible belt about the rolling elements. The flexible belt includes a twisted section defining a plurality of spiral edge segments operative to (i) frictionally engage a surface of the sheet material to urge the sheet material against the abutment surface and (ii) convey the sheet material along the conveyance deck.

A module in an envelope insertion station for transporting an envelope to an enclosure material insertion location, which uses endless belts to move the envelope until it is stopped by rotatable stops. A fixedly-mounted vacuum module having vacuum ports provides a suction force to the envelope urging the trailing edge of the envelope to press against the belts and provides the normal force required to move an envelope downstream as it enters the insertion deck without slippage against the translating endless belts. Additionally, a second vacuum module having vacuum ports provides suction force urging the leading edge of the envelope to press against the belts and provides the normal force required to prohibit the leading edge of the envelope from buckling during impact with the rotatable stops. The second vacuum module is removably mounted and mechanically linked to the rotatable stops so they can be repositioned together to accommodate different-sized envelopes.

A sheet feeder for feeding sheets from a sheet stack, having a feed deck for supporting the sheet stack and a pair of spaced apart parallel guide rails on the feed deck for receiving the sheet stack between the guide rails. A sheet feeding assembly is mounted in proximity to a sheet feeding end of the feed deck and is operative to feed individual lowermost sheets from the sheet stack, the sheet feeding assembly including a continuously rotating feed drum having an inner and outer circumference and a plurality of suction openings and a vacuum assembly received in the inner circumference of the feed drum and having at least one rotating cylinder coupled to a vacuum source and movable between an actuated position for drawing air downward through the portion of the feed drum extending above the planar surface of the feed deck and a default position preventing the drawing of air through the feed drum when a vacuum is applied to the at least one rotating cylinder.

An apparatus is provided for altering the spatial orientation and/or direction of sheet material. The apparatus includes an input deck for receiving sheet material along an input feed path, an output deck for forwarding sheet material along an output feed path, and an orbit nip roller assembly disposed adjacent to and aligned with the input and output decks. The orbit nip roller assembly includes a primary and secondary roller defining a roller nip which lies substantially parallel to the input and output feed paths. The secondary roller is adapted to be bi-directionally displaced in an arc about the periphery of the primary roller such that the roller nip orbits the primary roller from a first radial position to a second radial position. In the first radial position, the roller nip is adapted to accept sheet material from the input deck at a substantially right angle relative to the input feed path and, in the second radial position, the roller nip is adapted to dispense sheet material to the output deck at a substantially right angle relative to the output feed path.

A method of joining a first sheet-metal member to a second sheet-metal member in a right-angle relationship using an H-shaped interlocking member. An opening is provided near an edge of the second sheet metal member with a channel communicating the opening and the edge. The opening is sufficiently wide to allow the H-shaped member to be rotated therein so as to allow the upper and lower slots of the H-shaped member to engage with the second sheet-metal member. A tapped hole is provided in the center section of the H-shaped member, aligned with the channel, so as to allow a screw to be inserted through a hole on the first sheet-metal member and then the channel to engage with the tapped hole. After the screw is tightened, the surface of the first sheet metal member is securely joined to the edge of the second sheet metal member.

A method and apparatus for staging envelopes in a mail insertion machine. In the mail insertion machine, envelopes are moved into an envelope inserting area one at a time with the flap of the envelopes trailing the envelope bottom edge and flipped away so as to allow enclosure material to be inserted into the envelope. While one envelope is paused in the envelope inserting area for receiving enclosure material, the next envelope is moved towards the envelope inserting area such that the flap of the paused envelope in the envelope inserting area is partially overlapped with the next envelope in a shingling fashion. In order to properly separate these envelopes, a sensing device is used to sense the arrival of the bottom edge of the next envelope in order to control the further movement of the next envelope.

The present invention relates to locking and locating cylindrical components or roller sleeve assemblies on a support shaft. The locking feature is an anti-rotation device that prevents rotation of the roller assembly or sleeve assembly on the support shaft. The locking feature permits axial location of the component or sleeve to a pre-determined position as desired. A pair of over-running clutches or one-way clutches is used to facilitate the feature. The clutches are assembled to a receiving bore in the component or sleeve so that they are able to lock on the support shaft in reverse directions, thereby preventing rotation of those parts on the support shaft.

A method for supplying envelopes to an inserter system, including the steps of providing an envelope supply structure having an exit point, providing at least first and second supply paths from the exit point of the envelope supply structure and providing a common path from the at least first and second supply paths. Individual envelopes are fed from the envelope supply structure to a selected one of the at least first and second supply paths wherein the envelope is conveyed to a holding area in the selected supply path and from the holding area of the selected supply path it is conveyed to the common path. The envelope then travels from the common path to an envelope insertion area wherein prearranged documents are caused to be inserted into the envelope.

A system for in-line feeding from two cut sheet feeders comprises a first feeder for feeding cut sheets seriatim along a lower paper path originating at the first feeder, and first transport structure adjacent the first feeder for transporting sheets fed from the first feeder along the lower paper path. There is a second feeder mounted above the first transport structure for feeding cut sheets seriatim along an upper paper path originating at the second feeder. Structure is provided for merging the upper and the lower paper paths into a main paper path whereby sheets fed from the first and second feeders are merged into the main paper path for further processing. Wherein the first and second feeders each include structure for reading control information printed on the sheets fed from the respective feeder. The control information is used to control the first and second feeders, the first transport structure and the merging structure. The first transport structure includes at least one staging area for stopping the advancement of sheets fed from the first feeder when the second feeder is feeding. The merging structure includes upper and lower transport sections.
