ABSTRACT:
By means of a conveyor device, which possesses grippers arranged behind one another in the product conveying direction, the printed products are infed in an imbricated formation to at least one but possibly two or more stacker units. These stacker units are successively arranged in the product conveying direction below the conveyor device. Above each stacker unit there is located a release device for the grippers. In each case at least one of the release devices is located in its switched-on condition for opening the grippers moving therepast. The printed products are drawn by the conveyor device over the stacker compartment of the stacker units. The products released above the intended stacker compartment, upon opening of the grippers, drop essentially in vertical direction downwardly and after a short free-fall path arrive in such stacker compartment. While there is accomplished in the one stacker unit a stacking of the printed products there are not infed any printed products to the other stacker unit during such time that its stacker compartment is emptied. Thereafter to the extent necessary the one prior switched-on release device is switched-off and to the extent necessary the other release device is switched-on, so that now the arriving printed products can be stacked in the other stacker unit.
