摘要：By means of a conveyor device, which possesses grippers arranged behind oneanother in the product conveying direction, the printed products are infed in animbricated formation to at least one but possibly two or more stacker units. Thesestacker units are successively arranged in the product conveying direction below theconveyor device. Above each stacker unit there is located a release device for thegrippers. In each case at least one of the release devices is located in its switched-oncondition for opening the grippers moving therepast. The printed products are drawn bythe conveyor device over the stacker compartment of the stacker units. The productsreleased above the intended stacker compartment, upon opening of the grippers, dropessentially in vertical direction downwardly and after a short free-fall path arrive in suchstacker compartment. While there is accomplished in the one stacker unit a stacking ofthe printed products there are not infed any printed products to the other stacker unitduring such time that its stacker compartment is emptied. Thereafter to the extentnecessary the one prior switched-on release device is switched-off and to the extentnecessary the other release device is switched-on, so that now the arriving printed
products can be stacked in the other stacker unit.
