Abstract
A stacking device for pre-folded endless paper web in a paper stacker is provided with a stationary stack support or deposit surface and a piler means disposed for movement over the deposit surface for receiving and folding the paper web along its crease lines in zig-zag layers on the paper stack. The invention offers the advantage that the movable elements of the paper stacker have significantly lighter and constant masses, so that the inventive structure may be made less expensively than conventional, known paper stacker arrangements. Between the feed roll means delivering the paper web into the stacker and the relatively movable piler, there is provided a guidance means for conducting the paper web in non-collapsing fashion downwardly within the stacker to the piler. The guidance means is constructed so as to automatically vary in length in accordance with the changing working height of the piler during stacking operation. The guidance means may be in the form of a plurality of synthetic bands provided along opposed sides of the paper web wherein the bands are connected at their upper ends to automatic tensioning means which maintain the bands under tension and allow the bands to lengthen or contract in accordance with the relative movement of the piler.
