Abstract: A method and a machine for moving a stack of flat corrugated board sheets from a stacker to a delivery locus. A carriage is supported for fore-and-aft horizontal movement along a main frame and has a transverse frame member supported on said carriage for vertical movement, both the horizontal and vertical movement being power driven. A first series of vertical, horizontally perforated plates is secured against rotation to the transverse frame member, and a second series of vertical plates is supported so that they can be moved toward and away from the first plates by power means; the second plates have a series of horizontal pins projecting therefrom and aligned with the perforations through said first plates.
