ABSTRACT:
A stacking arrangement for lumber items in the form of planks and boards, particularly profile strips, in which at least two stacking units and a stacking element hold the lumber items. The stacking units and stacking element are movable vertically relative to one another, and the stacking element has a horizontally movable support arm and a transport device for conveying the lumber and depositing it on the support arm. A cylinder piston unit and a pivoted pawl is operably associated with the support arm and transport device. The support arm has a groove open upwardly to accommodate intermediate sticker layers which separate layers of the lumber items and to engage the free end of the pawl. The bottom surface of said groove and the upper surface of said support arm are inclined downwardly and forwardly to form a predetermined angle with the horizontal. The cylinder piston is located above the support arm, and the free piston rod end, facing the stacking element, mounts the pivoted pawl as well as a stop for the pawl. The pawl is stopped hanging vertically during a transport movement.
