-29- PACKAGE FORMING MACHINE ABSTRACT OF THE DISCLOSURE A package forming machine wherein one or more articles are packaged as a unit by the wrapping of a film of shrinkable plastics material thereabout, the film being provided as a continuous web. The machine is adapted to the packaging of plural articles arranged in a plurality of rows. The machine receives articles in nested rows and is provided with means for automatically bringing adjacent articles into transverse alignment. The articles are then moved in clusters to a wrapping station where a continuous film is engaged over the top of each cluster and held in- place by an upper conveyor while at the same time the cluster is being engaged by and supported by a lower con- veyor which moves in unison with the upper conveyor. Film drawing means then moves down between each pair of adjacent clusters and draws the necessary film, after which the film is severed into individual wraps followed by the directing of a rear bottom flap into underlying relation with respect to the rear part of the cluster. Thereafter, the partially wrapped cluster is moved onto a platform wherein the front flap is both tightly drawn with respect to the cluster and positioned beneath the cluster and the rear flap. The machine also includes spacer means movable in between par- tially wrapped adjacent clusters to stabilize and maintain the spacing thereof.
