Patent ID: 7716903

Claim:
A method of threading a sheet-like bale wrapping material from a roll through a bale wrapping mechanism, comprising the steps of: providing a first roll of bale wrapping material having a first axis of rotation in a first location and feeding it along a predetermined path through the bale wrapping mechanism; providing a second roll of bale wrapping material having a second axis of rotation in a second location generally above and parallel to the first roll; observing the first roll to determine when it is nearly exhausted of wrapping material, and, when that condition is observed: rotating the second roll about the second axis to feed wrapping material into contact with the wrapping material still being fed from the first roll in the first location, in the predetermined path, whereby the wrapping material dispensed from the second roll is pulled through the wrapping mechanism by the wrapping material on the first roll; wherein the second roll is connected to a selective drive, the selective drive rotationally coupling the rotation of the first and second rolls about their respective axes.
