Abstract: The invention uses a new system which cuts and unlocks a wrapping material (PE film) for cotton in a continuous manner in cotton harvesting, and a new method in production of such film. The film consists of many segments that make many bales of cotton. The film is separated with perforation by laser or other methods. A double sided adhesive is used to glue the bale at the end of it, which is covered by a folded bridge. The bridge connects both ends of the segments of the film. When perforated film is torn at a signal by the harvest machine, the bridge is unfolded as a leading edge for the next segment after a brief bridge linkage of both segments. The way of folding the bridge is key part of the invention, which accurately uncovers the end adhesive for the new bale and reduces the problem of tangling of the film at the time of separation.
