The bale-forming device is guided about first and second stationary deflection devices. Guides are positioned between the first and second stationary deflection guides. During a first bale-forming phase, the bale-forming device travels along a spatially determined movement path on the guides. During a subsequent bale-forming phase, the bale-forming device is transferred to additional movement paths that are independent of the guides and are determined by the diameter of the bale. The maximum bale diameter is selectable by moveable control devices. After the bale reaches the selected maximum diameter, the bale-forming device initiates a compression phase and exerts a compression force on the bale from the exterior to the interior of the bale.
