Abstract
The invention relates to a method and a device for wrapping a round bale pressed in a round bale press at least about its cylindrical surface area with an at least unilaterally adhesive film (12). With the inventive method, the film (12) is pulled off by means of a pulling-off device (6, 7) from a film roll (11) in its entire width. During a predetermined space o time of said pulling-off operation, a film rope (13) is formed from the film (12). Said film rope (13) is introduced into the gap between the round bales (3) to be wrapped and a device forming the circumferential press chamber wall (2). By setting the round bale (3) into rotation, the film rope (13) present in the gap is carried along. The round bale (3) is so long rotated until the desired number of film layers has formed on the surface area of the round bale.
