Abstract

The present invention relates to a method of forming a layup of wood veneer sheets and an apparatus suited for implementing said method. In the method, each of the sheets (1) is first taken separately into a forward-feed position on a level situated above the layup (2). Next, the sheet is lowered with its tailing edge first onto an intermediate platform located above the desired laying point in the layup, and further therefrom, the sheet is lowered with its leading edge first onto the layup. The apparatus includes a conveyor (6) arranged to run as an endless loop. The conveyor is adapted to perform a continuous loop travel during the entire cycle of the sheet-laying sequence. The conveyor bars supporting the sheet are omitted from a given section of the conveyor loop thus facilitating a stepwise lowering of the sheet onto said intermediate platform, and therefrom, further onto the layup. The alignment of the sheet is accomplished by means of a tailing edge stop (4).
