  • Patent number: 6332309
    Abstract: A round baler for agricultural harvested crop and including a variable volume bale chamber having a delivery opening and limited, in an axial direction, by side walls of the baler housing and, in a radial direction, by at least one flexible transporting and pressing belt, which is guided over deflection rolls, and by at least one pressing roller which is arranged adjacent to a respective deflection roll, a pivot device supported in the baler housing for pivoting the transporting and pressing belt, with increase of a bale diameter, from a start position of the transporting and pressing belt into its end position, and elements for positively shifting a radial position of at least one pressing roller or the respective deflection roll relative to the bale chamber dependent on the pivotal movement of the pivot device.
