INVENTOR: WALTER REISTINVENTION: APPARATUS FOR FORMING A SPIRAL-LAYERED COILED STACKFROM SUBSTANTIALLY TWO-DIMENSIONAL FLAT STRUCTURESCONTINUOUSLY ARRIVING IN IMBRICATED FORMATIONABSTRACT OF THE DISCLOSUREA stack support rotating about an upright axis isarranged beneath a discharge station of a delivery conveyor forthe imbricated formation. The stack support and at least thedischarge station of the delivery conveyor are adjustable inheight in relation to one another. In order to increase thestorage capacity of the spiral-layered coiled stack beingformed, respectively in order to reduce its height for the samecontent, a drive mechanism is provided to periodically displacethe discharge station of the delivery conveyor and the axis ofrotation of the stack support relative to one anotherperiodically and alternatingly toward and away from oneanother. A spiral-layered coiled stack thus forms in whicheach layer of the coil consists of a flat spiral preferablycomprising a plurality of spiral windings progressing from theinterior to the exterior and from the exterior to the interiorin alternate layers.
