Apparatus for absorbing energy during signature delivery

摘要

The present invention is related to an apparatus for delivering flat products, such as signatures, in a folding apparatus of a rotary printing press. At least one fan wheel assembly has a plurality of fan blades separated from each other by fan wheel pockets. The fan wheel pockets are defined by surfaces of the fan blades. A first surface of each fan wheel pocket is configured to cause the signature to take on an energy dissipating state.
