Apparatus for wrapping articles with shrinkable film and comprising, in combination, an endless article conveyor means having an article receiving end and an article delivery end, the conveyor means comprising a plurality of parallelly disposed belts having gaps formed between adjacent belts and being adapted to run continuously. Means are provided for sequentially delivering articles to be wrapped in a first predetermined spaced relationship onto the article receiving end of the conveyor, and means provided adjacent the receiving end for applying a wrap of film about the articles being wrapped and for enclosing the articles within a tubular container or enclosure with an axis parallel to the direction of motion of the conveyor. A transverse welding and severing bar is provided for severing the film between adjacent spaced wrapped articles, and for forming a transverse welded closure about the articles, and in order to reduce the tension on the film between adjacent articles, means are provided to stop or retard the motion of each article as its trailing edge passes beyond the zone of the welding bar, this motion interrupting or retarding mechanism effectively reducing the tension in the wrapping film which would otherwise be established between the successive articles as the welding bar moves downwardly into contact with the film surfaces being sealed.
