  • Patent number: 5257688
    Abstract: A device for dividing a collection of wood pieces and piecemeal cross feeding thereof in a direction away from the collection place comprises a feeding arrangement (2), which is moveable reciprocatingly in a substantially rectilinear, sloping movement path (3) for feeding the wood pieces along a rising support path (4). The feeding arrangement and the support path both have a stairs-like design with a plurality of steps (6, 7), which in profile have substantially similar form and each of which comprises a first portion (9) sloping upwardly in the direction of rise of the support path followed by a downwardly sloping second portion (10). The steps (6, 7) of the feeding arrangement and the support path are mutually displaced, viewed perpendicularly to the first portions (9) of the steps, with a measure smaller than the length (1.sub.2) of the second portions (10). The first portions (9) of the steps (6, 7) of the feeding arrangement as well as the support path have a steeper slope than the movement path (3).
