发明名称 Method of wrapping roll bales with plastic film
摘要 A method used to wrap roll bales of crop material with plastic film. The method involves holding the end of a supply roll of plastic film between stationary feed rolls as a bale is formed, and then delivering the end of the plastic film to the outer surface of a completed roll bale by driving the feed rolls. The method also involves wrapping the roll bale with a suitable number of layers of the plastic film by driving the feed rolls while rotating the roll bale, and then severing the plastic film at a location between the roll bale and the feed rolls by stopping the feed rolls and moving a cutoff bar into contact with the plastic film while continuing to rotate the roll bale.
