A wrap-around packaging method wherein a package blank is prefolded to an open-sided configuration, an object to be packaged is positioned within the prefolded blank and the final folding and adhesive closing of the package is then completed in a series of synchronized steps. The prefolding occurs during the course of withdrawal of the package blank from a magazine and its transporting into position to receive the object to be packaged and includes plural folding steps which are individually performed to minimize stress on the packing material. The movement of the preformed packing material blank and object through the final folding and closing stations is accomplished without contact between the conveying means and the object.

A method of folding an initially flat package blank at least partly about an article so as to define a generally rectangular-shaped receptacle for the article, the blank having a plurality of regions which define parallel longitudinal fold lines, said longitudinal fold lines defining edges of adjoining sides of the receptacle, the blank further having portions which define closure flaps, said method comprising the steps of: preforming the blank by bending about each of the side edge defining parallel longitudinal fold lines thereof to define an open-ended and open-sided packing having a bottom side, the preformed packing also having a front side which extends generally transversely with respect to the bottom side; supporting the open-sided packing on its bottom side; positioning an article to be packaged on the inwardly disposed face of the open-sided packing bottom side, the open-sided packing and article comprising a pack unit; folding a first closure flap of the package blank inwardly to cause said flap to be orientated generally parallel with respect to the pack unit front side; and moving the pack unit to at least a first folding station by the application of force solely to the open-sided packing.
