Abstract
A film-tail clamp, cut, and seal system for use in a wrapping apparatus for wrapping an associated item has an oval track vertically oriented and openable to move into and out of the associated item. A shuttle is configured for movement along an inner periphery of the track. A wrapping material is dispensed from the shuttle for wrapping around the item. A clamp arm, which is movable into and out of a plane defined by the film being wrapped around the item, has a sealing element for contacting and sealing a free end portion of the film onto a portion of the film already wrapped around the item. The clamp arm also has a clamp for securing the film when the film is sealed and has a cutter for cutting the free end portion of the film from the portion sealed onto the film.
