The invention refers to an apparatus and a method for forming a bale (B) in a bale forming chamber and for wrapping the bale (B) outside of the bale forming chamber. While the bale (B) is wrapped, the bale is rotated and is kept in a wrapping position between a bale forming means ( 10, 11 a, 11 b, 11 c, 11 d, 12, 13, 15, 18) surrounding the bale forming chamber and a bale supporting device (9) outside of the bale forming chamber. The bale (B) is thereby sandwiched.
