Abstract: A mistake detector for an In-Line Inserter includes complementary metallic detecting rolls positioned slightly downstream of ejection rolls of a pull-foot sheet feeding system. One of the detecting rolls is moveable and is attached to a detection feeler which is positioned between detection points. The detection points are also moveably mounted so that their positions can be overridden by excessive movement of the detection feeler.

Abstract: An in-line inserter device comprises envelope and insert feeding assemblies, a stuffing-station assembly and a sealing and stacking assembly. The envelope feeding assembly withdraws envelopes from a hopper-held envelope stack and conveys them along an involute path toward the stuffing station. The insert feeding assembly comprises a plurality of hopper-held insert stacks which are positioned in line with an insert conveyor. The insert conveyor carries dispensed inserts from the hopper-held insert stacks to the stuffing station. The stuffing station assembly coordinates operation of the insert and envelope feeding assemblies in a special way to efficiently accomplish the stuffing of the inserts into the envelopes. Subsequent to such stuffing, filled envelopes are conveyed from the stuffing station, sealed, and stacked by the sealing and stacking assembly.

Abstract: A sheet transporting system for transporting sheets from a pull-foot feed mechanism to a stuffing station includes parallel fast and low-speed endless conveyors. The low-speed endless conveyors have pins thereon which extend into the path of sheets transported by the fast endless conveyors. The pins register, and control the speed of, sheets being transported. This transporting mechanism is used in one embodiment for transferring sheets from the pull-foot feeding system into the mouths of clamps on a transporting chain and in another embodiment for transferring sheet to a drum/belt transporting system.

Abstract: Disclosed is a document handler and feeder device for performing high speed separating and transporting of documents, such as business forms. The document handling unit is equipped with friction type feed rollers and a lipped contour plate over which documents must pass. The feed rollers contact and transport a foremost document from a gravity-feed document hopper. High speed tracking belts, are mounted over grooves or tracks, which extend along a track plate and through the lip of the contour plate. The feed rolls force the leading edge of the foremost document into the lip where the document engages the bottom side of the belts so that it is nipped between the belts and the contour plate causing the document to move into the tracking grooves.The contour plate has a transition radius between its lip and the base of the document hopper upon which the foremost document rests.
