<p>A stacking apparatus for articles, especially printed products, comprising a stacking chute or channel which can be loaded from its top end with the printed products and at least one pair of press or contact elements which can be driven to-and-fro in the lengthwise direction of the stack chute and arranged at one side thereof. These press or contact elements periodically engage into the confines of the stack chute, in order to exert a pressure force upon the momentarily uppermost located printed product of the printed product stack. To obtain an uninterrupted action of the pressure or contact force, the press elements, which preferably have the shape of pawls, are arranged almost above one another. The one press element of the pair is driven in counter cycle, i.e., out-of-phase in relation to the other press element.</p> |
