ABSTRACT:
Apparatus for wrapping articles in heat sealed thermoplastic stretchable film consists of a first conveyor for carrying an article forward while progressively enclosing it with film drawn from a film supply, joining the margins of the film together to enclose the article in an elongated tube of film, cutting the film so as to provide equal amounts of excess film at each end of the article, using a vacuum inlet to pull the trailing portion of film to one side of the article so that a transverse rod, moving faster than the article, can fold the trailing portion against one side of the article, folding the leading portion of film against the same side by means of a roller, and finally moving the article into contact with a heated belt to seal the film.
