ABSTRACT:
A wrapping machine wraps articles, such as vegetables and meat carried on trays, in sheets of stretchable film. A lifting platform lifts the articles into the film sheet at a wrapping station and wrapping blades engage each edge of the sheet to stretch the sheet and move the edges under the article. The wrapped article is pushed away from the wrapping station to a discharge conveyor where the film is heated to seal and secure the film around the article. The film sheets are fed in predetermined lengths to the wrapping station from a roll of film.
