Abstract: A system and method for controlling a wrapping process of a round bale is disclosed. The round bale rotates in a bale chamber of a round baler with elastic wrapping material being removed from a supply roller using a tensioning device and guided during the wrapping process by at least one guide roller. The round bale is wrapped with the wrapping material pretensioned by the tensioning device with an adjustable wrapping tension predetermined by the control unit. A sensor assembly may sense the actual value for a force resulting from the wrapping tension, which is compared with a target value for the force resulting from the wrapping tension, which is determined during the performance of at least one preceding wrapping operation and specific to the wrapping material. The control unit controls the tensioning device depending on the deviation determined by the comparison of the actual value and the target value.

Abstract: An agricultural round baler has an interior space enclosed by a housing, a feeding device, a plurality of guide rollers, a press belt and an adjusting device with at least one adjusting roller. At least one of the guide rollers is a drive roller that drives the press belt. The press belt defines a press chamber which interacts with the transfer cross section. The adjusting roller is positioned along the running track of the press belt so that at least one running track section at least partly delimits the press chamber. The adjusting roller is moveable within the interior space so that at least one part of the running track of the press belt is moveable. A second adjusting device is operationally combined with the first adjusting device to define the press chamber. The adjusting roller of the second adjusting device is moveable within the interior space.
