ABSTRACT:
Apparatus and method for the automatic packaging of one or more articles. An adjustable web guide structure that guides the webs of film into a configuration that mimics the geometry of a package to be wrapped is provided. The webs are conveyed over the guide structure, which structure provides an appropriate predetermined shape defining a web envelope for proper package entry and flow through the wrapping system. The position and geometry of the guides causes the web envelope to form around the corners of the product to be package to minimize film requirement, and allows for fluid transition from web supply rolls to package shape. External tension rods can be used to assist in preventing or minimizing web wrinkling. Guide rolls can be used in conjunction with the guide structure to assist in guiding and tracking the web material, as well as to provide axial transverse tension for proper web forming.
