Air delivery apparatus for delivering air to a moving substrate in a printing press

摘要

An air delivery apparatus for providing air to guide a web in a printing press that includes a source of compressed air and a web guiding device coupled to the source of compressed air is provided. The web guiding device includes a body and a guide. The body defines an internal cavity and has an axis, an inner surface, an outer surface, holes extending from the inner surface to the outer surface and an axial end having an opening coupling the internal cavity to ambient air. The guide couples the source of compressed air to the internal cavity and directs the compressed air in an axial direction away from the axial end toward the internal cavity so that the ambient air is forced into the internal cavity. A method of delivering air to guide a substrate is also provided.
