ABSTRACT:
A packaging apparatus for folding the front and rear ends of a tubular film which covers an article toward the bottom surface of the article. After the front end of the film has been folded while the article is transported, a bar-like roller traveling along the bottom surface of the article at a higher speed than the transport speed of the article catches the rear end of the film and folds it. An air blowing device is installed along the path of travel of the bar-like roller. The air from the air blowing device presses the front and rear film ends against the bottom surface of the article. Thereby the front and rear film ends are prevented from being contacted by the bar-like roller which would strip it from the bottom surface of the article.
