Abstract
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.
Claims8
An apparatus for stacking products, especially printed products, and in particular folded printed products, comprising:
- means defining a stacker chute for the products, such stacker chute being structured to be loadable from an upper region thereof with the products to be stacked;
- at least one pair of press elements arranged at one side of the stacker chute;
- means for driving said press elements to-and-fro in the lengthwise direction of the stacker chute and for periodically engaging into the confines of the stacker chute, in order to press against the uppermost product of the product stack;
- means mounting said press elements of each pair so as to be almost arranged above one another;
- and
- said means for driving including a mechanism for driving one of the press elements of the pair in a counter cycle to the other press element of the pair.
