Abstract:
A method for producing cross stacks (12) from flat objects (7), wherein the objects (7) are supplied to be stacked being conveyed serially along a conveying track (3) individually held and aligned with one another and are stacked in stack sections rotated relative to one another by 180Â° around a stacking axis, and wherein, prior to being stacked, the objects (7) are subjected to one of a first step sequence or a second step sequence in alternating groups, wherein in both step sequences the objects (7) are released from held conveyance to be conveyed to the stacking, in at least one of the step sequences the objects are lying in an imbricated formation on a conveying surface and wherein the two step sequences together comprise at least one rotation step (A, B, C) such that there is a rotation difference of 180Â° around an axis perpendicular to the object surfaces between the two step sequences, and wherein the objects (7) are stacked alternatingly in groups from the first and from the second step sequence.
