The present disclosure provides embodiments of a lapper assembly for use to overlap successive sheets of wood veneer or other materials along a conveyor. The lapper assembly may include a stop member configured to be rotatably mounted to a roller such that the stop member is pivotable around the rotational axis of the roller independently of the rotational angle of the roller. The lapper assembly may further include a lever arm coupled to one end of the stop member. An actuator may be pivotably coupled to the lever arm and the conveyor frame, and operated to pivot the stop member between a workpiece engaging position, in which the stop member extends into the path of workpiece flow, and a workpiece disengaging position below the path. Optionally, the lapper assembly roller and other rollers upstream/downstream may be operatively connected to a drive. Corresponding systems and methods are also disclosed herein.

A document feeder includes: a first conveyer that picks up sheets from a sheet bundle sheet by sheet, where rear edge of a preceding sheet overlaps front edge of a succeeding sheet; a second conveyer that conveys each sheet picked up by the first conveyer; a front edge sensor that is disposed on a conveyance path from the first conveyer to the second conveyer, and senses whether the sheet falls within a sensing range; and a shift unit that shifts, while the first and second conveyers convey the sheet, positional relation between the sheet and the front edge sensor by increasing distance therebetween in a direction crossing a sheet conveyance direction, such that the sheet falls outside the sensing range. When the preceding sheet falls outside the sensing range, the first conveyer picks up the succeeding sheet such that the front edge of the succeeding sheet enters the sensing range.

A sheet feeder comprises a roller configured to rotate about an axis and an input drive configured to deliver single sheets to the roller such that a leading edge of each sheet is substantially parallel to the axis. The roller comprises a plurality of flexible fins extending along the axis. As the roller rotates, one of the sheets can be lifted by the rotating fins to pass over the roller, while the leading edge of a following sheet is delivered to the roller in an underlapping relationship with the first sheet.

A sheet conveyance device includes: a container that accommodates loaded sheets; a feeding mechanism that continuously feeds the sheet from the container; a conveyance path on which the sheet is conveyed; and a pitch adjustment mechanism provided on the conveyance path and which adjusts a pitch of a preceding sheet and a subsequent sheet, wherein the pitch adjustment mechanism includes a pitch adjustment roller pair including a first pitch adjustment roller and a second pitch adjustment roller that sandwich the conveyance path and are in pressure contact with each other, the first pitch adjustment roller is driven and rotated in a direction following a sheet conveying direction, the second pitch adjustment roller is driven and rotated in the direction following a sheet conveying direction, and the second pitch adjustment roller is connected to a drive shaft that drives the second pitch adjustment roller via a one-way clutch.

A recording apparatus which is capable of suppressing or avoiding a concern on a defect such as a paper jam, deterioration of recording quality, or the like at the time of performing an overlapping transportation is provided.

Embodiments of a system and method for shingulating, singulating, and synchronizing articles in an article feeder system are disclosed. The article feeder system may include a shingulating device configured to receive a stack of articles and to produce a positively lapped stack of articles, a plurality of picking devices configured to pick one or more articles from the positively lapped stack of articles and to produce one or more singulated articles, and one or more synchronization devices configured to deliver the one or more singulated articles to one or more sorter windows.
