A stack support rotating about an upright axis is arranged beneath a discharge station of a delivery conveyor for the imbricated formation. The stack support and at least the discharge station of the delivery conveyor are adjustable in height in relation to one another. In order to increase the storage capacity of the spiral-layered coiled stack being formed, respectively in order to reduce its height for the same content, a drive mechanism is provided to periodically displace the discharge station of the delivery conveyor and the axis of rotation of the stack support relative to one another periodically and alternatingly toward and away from one another. A spiral-layered coiled stack thus forms in which each layer of the coil consists of a flat spiral preferably comprising a plurality of spiral windings progressing from the interior to the exterior and from the exterior to the interior in alternate layers.
