ABSTRACT:
An apparatus for ejecting stacks of flat products, especially printed products from a receiver chute of a stacker device. The stack supported upon a support table which closes the receiver chute at its lower end is displaced by means of a forward and rearward movable ejection element from the support table. The ejection element is secured to one end of a flexible, spatially movable thrust and traction element, for instance a ball-and-socket chain. At the other end of the thrust and traction element there engages a drive unit, for instance an hydraulic or pneumatic piston-and-cylinder unit. The thrust and traction element is guided by a guide having a stationary part and a section which travels in the support table which changes its position. In a rest position of the support table the section travelling in the support table is in alignment with the stationary part of the guide. During its displacement over the support table the ejection element bears at the support table, preferably by means of rolls.
