Device for displacing pieces of wood

The invention relates to a device for displacing timber pieces (2) longitudinally when adjusting timber pieces comprising a carrier-provided (3) transverse conveyor (1)， stops (6) arranged to abut and displace the timber piece longitudinally， an endless path (4) with which the anchors (6) are driven synchronously with the transverse conveyor (1)， the anchors (6) being slidably mounted on units which are movable along it， displacing means (5) arranged so that in a positioning area (X， Z) displacing the anchorage (6) in a transverse direction towards the movement along the path for displacing the pieces of wood (2) in the longitudinal direction. For increased efficiency， the device comprises at least two in the transverse direction of the endless conveyor (4)， in relation to! independently adjustable displacement means (5)， a docking device with a guide rail (13) arranged for each displacement means (5) having a first end (13a) and which is adjustable over a width (X) of the positioning area (X， Y) in the transverse direction of the endless conveyor (4)， a first follower (12) arranged for each stop (6) which can be brought into controlled cooperation with a guide rail (13) at a transfer point， an entrance end (14) to the positioning area (X， Y) where said input end forms a determined zero reference (0-ref) for adjustment with respect to the width of the positioning area (X) for abutment (6) which can be brought into cooperation with a guide rail (13) which is positioned at a handover point.
