Method of wrapping a round bale compacted by a round baler, film-wrapping device and round baler that is provided with such a film-wrapping device

A method for wrapping a round bale pressed in a round bale press about at least a cylindrical surface area with an at least unilaterally adhesive film, the method the method comprising

• pulling the film off from a film roll in its entire width by means of a pulling-off device;
• forming a section of a film rope by twisting the film during a predetermined space of time of the pulling-off operation according to the pulling step;
• introducing the film rope into a gap between the round bale to be wrapped and a device forming a circumferential press chamber wall;
• rotating the round bale so that the film rope present in the gap is carried along the cylindrical surface area;
• wrapping the bale with a portion of the film at its entire width following the section of the film rope;
• continuing to rotate the round bale until a desired number of film layers of the film have formed on the cylindrical surface area of the round bale;
• forming another film rope shortly before the desired number of film layers have been wrapped on the round bale;
• cutting the film web between the round bale and the film roll;
• outputting the round bale from the round bale press;
• transferring the round bale to a wrapping table;
• and
• wrapping the round bale completely with film.
