ABSTRACT:
A workpiece subdivided into a plurality of pieces ordered in closely juxtaposed rows is deposited on a stripping tray at an upstream end of a longitudinal path with the rows extending generally perpendicular to the direction and then an upstream edge of the tray carrying the subdivided workpiece is positioned above an upper surface of one of a plurality of distributing units spaced longitudinally along the path and a stripping bar vertically closely juxtaposed with the tray and extending transversely across the tray immediately downstream of the subdivided workpiece is shifted into engagement with the leading edge of the subdivided workpiece on the tray to slide the trailing row of pieces off the tray onto the surface positioned thereunder. The tray is then displaced downstream and stopped with its trailing edge above each of the other distributing units thereon and the deposition step is repeated to deposit on each of the units a respective row of the pieces. Immediately after each unit receives the respective row of pieces, its upper surface is vertically shifted from an upper position immediately beneath the level of the stripping tray to a lower position and then the upper surface is shifted transversely to displace at least one of the respective row of pieces transversely and transfer same to respective longitudinally spaced takeoff conveyors adjacent the path and having upper surfaces at the lower level.
