<p>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 (29) comprising a combination of: a plurality of trolleys (25) equipped with lances (27) capable of moving forward and backward from the reception area of a stack of section bars (12, 12b) to a deposition area of the same layer of section bars (12, 12b) in an upright position, and a plurality of magnetic heads (13) capable of being actuated to rotate by a first set of actuating means (23, 24) from a picking-up position of another layer of section bars (12a, 12c) to a depositing position of the same layer of section bars (12a, 12c) reversed on top of the first layer of upright section bars (12, 12b). According to the invention, each head (13) is provided with both a vertical shifting motion essentially parallel to itself and an oscillating motion, where the said shifting motion is actuated by a second set of actuating means (20, 21) independent of the first (23, 24) and the said oscillating motion is actuated by a third set of actuating means (38, 39, 42) also independent of the first set (23, 24). <IMAGE></p> |
