ABSTRACT:
A machine for wrapping a plurality of articles into a package. The machine is provided with a film which comes in roll form and the film passes through a cutter but does not cut it entirely off. At the same time, generally parallel to the film there is a row of articles which are advanced and passed on to a guide which moves them onto the film. The film is then drawn after which the articles are advanced in unison and then the film is drawn about the articles. The group of articles are then passed on to rollers and into a shrink tunnel for shrinking of the film so as to tightly engage the articles. As the film is pulled into loops, the loops are supported by a vacuum conveyor so that the loops will stay ready for the eventual drawing of the film about the group of articles.
