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.

The invention relates to a device for feeding products in sheets into an insertion device before a digital printer, including a lifting system for a stack of laminar elements, which in turn includes an extraction mechanism for the last board, an insertion system with an advance mechanism, a rotation system for the stack(s), a positioning stop, connected to an advance and reverse mechanism, a squaring and scaling station, able to create a loading and accumulating hopper, and a telescopically-adjustable transportation system, with the capacity to move the previously-scaled sheets until the insertion device is fed.

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.

A printing apparatus includes a printing cylinder (14) that can hold sheets (4) and transfer them one by one continuously, first to fourth inkjet heads (41-44), and a feeder unit (2). The printing apparatus includes a speed reducer (72) that switches the speed of the feeder unit (2) between single-sided printing and double-sided printing. In single-sided printing, the feeder unit (2) is driven at a first supply speed at which the sheets (4) are supplied to the printing cylinder (14) one by one continuously, and the printing cylinder (14) is driven at a transfer speed at which the sheets (4) supplied from the feeder unit (2) one by one continuously are transferred. In double-sided printing, the printing cylinder (14) is driven at the transfer speed, and the feeder unit (2) is driven at a second supply speed that is the first supply speed. The printing apparatus that operates stably in both single-sided printing and double-sided printing can be provided.

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.
