ABSTRACT:
An apparatus for compressing or squeezing a stack of folded, essentially flat products, especially printed products, comprising a stack receiver compartment closed at its lowr end by a support element and a counter pressure device arranged above the support element. The support element and the counter pressure device are movable relative to one another, in order to press together the stack arranged between the counter pressure device and the support element. The counter pressure device comprises at least one pressing element pivotable about an essentially horizontal pivot axis. The pressing element spans over the stack receiver compartment in the direction of the pivot axis. This pressing element can be rocked upwardly by a product stack, out of a lower pivotal position inclined in the direction of the support element, against the action of at least one pressure element acting upon the pressing element.
