ABSTRACT:
An arrangement for turning and multiple placing on top of each other and for alignment of paper stacks which are located on the rear contact plate of a turning stacker in a position preferably turned by 90.degree.. Intermediate members in the form of a rake are placed between the individual paper stacks and are adjusted at the carrying column of carrying plate of the stacker. After introducing the paper stack and the intermediate member, the paper stack is preferably turned by about 90.degree.. The entire surface of the rear contact plate of the turning stacker is thereupon vented by uniform air discharge. The paper stack is loosened and aligned by forming an air cushion under the stack and then turned to a final position. The carrying plates or carrying forks between which the stack to be turned is held, is provided each with one yoke, or connected by one yoke having rear spindle nuts fastened on a left- and right-hand spindle. The yokes of the carrying plates or carrying forks are guided with sleeves on column-like supports. The yokes mount limit switches for restricting the movement which actuate the device for initiating the turning process.
