Abstract
Apparatus for wrapping an article with stretch film. The article is first advanced against a vertical web of film to partially enfold the film longitudinally about the article and to advance the article to a longitudinal folding station where a tail of the film is folded up against the bottom of the article and at which film wings laterally project from the article. The partially wrapped article is then advanced to a stretch and lateral fold station at which the film wings are clamped by clamping jaws which are moved laterally away from the article whereby to stretch the film. The article is then lifted and the clamping jaws are advanced toward each other and beneath the bottom of the article whereby to fold the wings at least partially against the article while maintaining stretching tension on the film. Thereafter, the article is advanced through a plow to complete the wrapping of the wings against the article.
