A stacking machine for stacking elongated members in a stack comprises a frame and a pair of cooperating stackers mounted thereto distant from each other. Each of the stackers comprises a driven master wheel, a slave wheel mounted eccentrically from the master wheel, a stacking arm assembly concurrently mounted to the master wheel and the slave wheel causing the master wheel to drive the slave wheel and a stacking arm assembly mounted to the stacking arm assembly, the stacking arm assembly comprising a stacking blade extending substantially parallel to the master wheel and defining a stacking face. The stacking faces of the cooperative stackers define a stacking plane supporting a layer of elongated members to be stacked, whereby the layers are moved one at a time on a stack.
