Patent ID: 7114311

Claim:
A method for automated wrapping of a bundle with a resilient stretchable film, comprising the steps of: i) unrolling a desired length of said film from a roll, said film having a first panel over a second panel, said panels being interconnected at a sealed first end and at a fold line; ii) sealing a second end of said panels to bond them together by a second seal at said desired length; iii) cutting said film along said second seal to form a bag; iv) separating said first panel of said bag from said second panel by grasping a portion of each said panel of said bag, whereby said bag may be opened at an end opposite said fold line; v) loading said bag in an opened position on four film handling assemblies of a stretching apparatus; vi) stretching said bag by expanding said stretching apparatus by displacing at least two of the film handling assemblies; and vii) covering the bundle with said bag, by displacing the stretching apparatus towards the bundle, whereby said stretched bag is gradually released from said film handling assemblies onto said bundle in a stretched resilient condition.
