ABSTRACT:
A stacker for the stacking of metallic section bars in alternating upright and reverse layers in an orderly manner, in particular of section bars originating from rolling mills by a conveying line which includes a plurality of trolleys equipped with lances capable of moving forward and backward from the reception area of a stack of section bars to a deposition area of the same layer of section bars in an upright position, and a plurality of magnetic heads capable of being actuated to rotate by a first set of actuating members from a picking-up position of another layer of section bars to a depositing position of the same layer of section bars reversed on top of the first layer of upright section bars. According to the invention, each head performs both a vertical shifting motion essentially parallel to itself and an oscillating motion, where the shifting motion is actuated by a second set of actuating mechanisms independent of the first and the said oscillating motion is actuated by a third set of actuating mechanisms also independent of the first set.
