  • Patent number: 8613585
    Abstract: The invention concerns a method and an arrangement for stacking timber packages in layer that uses a transfer arrangement comprising mobile carrier planes. The carrier planes in turn form a direct continuation of an input transporter in order to receive layers fed from this transporter by being caused to lift from below a complete layer from the input transporter and displacing the layer in over the stacking table. After that, the carrier planes are withdrawn from the stacking table while the layer of timber is scraped off from the carrier plane or, the stacking table is arranged to move downwards. The transfer arrangement uses a first, a second and a third carrier plane which are arranged to move mutually in a cycle in such a manner that one pair of two consecutive carrier planes is located at the same time at a position above the stacking table.
