Bale, an apparatus and a method for the wrapping of a bale in two crossing wrapping layers applied in overlapping helical turns

A method for wrapping a bale of organic material, such as animal-feed for ensiling, straw or hay, in bands of plastic packaging film, said bale having a first axis and a second axis, said first axis being generally longitudinally directed and said second axis being generally transverse to said first axis, comprising the steps of:

• dispensing plastic packaging film from a packaging film supply roll spaced from the bale while maintaining the plastic film under tension,
• wrapping the packaging film around the bale in successive turns with the packaging film supply roll being in an orientation generally transverse to said first axis, the film in each turn around the bale having first turn parts which extend generally parallel with said first axis and second turn parts which extend transversely to said first axis,
• dispensing further film material from a film material supply roll spaced from the bale while maintaining the further film material under tension,
• wrapping the bale (1) with further film material (9) with the film material supply roll being in an orientation generally parallel to said first axis, while maintaining the further film material under tension, such that successive film turns (9") of said further film material will cross-over the first turn parts (9'") of the packaging film which extend generally parallel to said first axis (3) in an elastically tensioned and wrapper retaining fashion.
