Abstract: In an envelope stacker, a pusher mechanism continuously applies a force to the envelope flap for sealing the envelope. The stacker is comprised of a horizontal deck, a rear wall, and a plate for supporting a stack of envelopes. Upon receiving an envelope, a pusher advances the envelope towards the stack of envelopes while applying a continuous force to the flap and rear panel of the envelope.

Abstract: An interlock mechanism is provided for a document handler having a pair of drawers for storing documents to prevent the simultaneous extension of more than one of the drawers. The drawer interlock apparatus comprises a frame and a longitudinal rail mounted to a side wall of each drawer. Each rail has a pair of substantially L-shaped stops and a locating notch positioned between the stops. A locking mechanism is pivotally mounted to the frame. The locking mechanism is slideably engaged with the rail of each drawer for preventing the simultaneous extension of the multiple drawers. Each drawer also has link mechanisms for adjusting drawer alignment to meet document registration requirements.

Abstract: The present invention provides an improvement for a document feeder comprising a feed deck, a separator assembly for separating and feeding individual documents, the separator assembly including a separator wheel disposed above the feed deck, drive structure for driving the separator wheel, and structure for adjustably positioning the separator wheel assembly to a position relative to the feed deck commensurate with the material being fed. The improvement comprises structure for pivotally coupling the document feeder to vertical frame members. The coupling structure is located at one end of the document feeder near the separator assembly. There are a pair of leg members extending below the feed deck, each of the leg members resting on a horizontal frame member at opposite sides of the document feed path. The leg members are laterally spaced so as not to interfere with documents being conveyed by the underlying document transport.

Abstract: In apparatus for feeding respective sheets including framework and a deck mounted thereon for supporting a plurality of sheets in an upright stack thereof, wherein the deck defines a path of travel for respective lowermost sheets to be fed from the stack, and the stack has an upstream end and a downstream end, an improvement for facilitating feeding lowermost sheets from the stack, the improvement comprising a platform connected to the framework, the platform including a base wall portion having a longitudinal length extending upstream from the upstream end of the deck; a stack supporting member, the member including an upright upper wall portion having a lower end, the member including a lower wall portion extending upstream from the upper wall portion's lower end and forming therewith an elongate downstream marginal edge having a wedge-shaped transverse cross-section; and structure for adjustably mounting the stack supporting member on the platform, the mounting structure including first structure for movin

Abstract: Apparatus for feeding respective sheets from a stack thereof comprising structure for supporting a plurality of sheets in an upright stack thereof, the supporting structure including an upright wall, the supporting structure including a deck extending beneath the wall and defining a path of travel for respective sheets fed from the stack, the deck extending transverse to the path of travel; structure for successively feeding respective sheets downstream in the path of travel, the feeding structure including opposed outfeed rollers downstream of the upright wall, the feeding structure including an elongate first roller longitudinally extending transverse to the path of travel upstream of the upright wall, the feeding structure including an elongate second roller longitudinally extending transverse to the path of travel upstream of the fist roller, the feeding structure including structure for driving the outfeed and first and second rollers; structure for controlling the driving structure, and the controlling

Abstract: Apparatus for cross-folding paper sheets, including: a first folding device for imparting a first fold to a paper sheet; a transport module secured to the first folding device for receiving a once folded paper sheet, and a second folding device oriented perpendicular to the first folding device and secured to the transport module, wherein the transport module includes a pivotable paper stop assembly having a self-centering stopping surface to stop and align the once folded paper sheet and a brush for controlling bounceback of the once folded paper sheet.

Abstract: A folding machine buckle chute with means for accessing paper jams is provided. The access means, comprising two pivotable sidewalls secured by a doubleslotted latch, allows for simple and rapid removal of jammed sheets from the buckle chute without disassembly.

Abstract: Apparatus is disclosed for aligning, i.e., de-skewing, sheet material having squared upstream and downstream edges which is being advanced along a path. The advancing apparatus includes a pair of endless belts having pushers projecting therefrom which engage the upstream edge of the sheet material to advance the sheet material with rotation of the belts. The disclosed apparatus adjusts the relative positions of the pushers so that the squared upstream and downstream edges of the sheet material are normal to the path of travel of the sheet material. The invention has particular application to mailing machines in which paper sheets to be inserted in envelopes are advanced towards a folding station and/or an envelope insertion station. The invention has particular application to use with apparatus that cross folds paper.
