In known large round balers, a rotating side wall is provided that can be pivoted away from a baling chamber either in a straight line or about a pivot axis, so that the pressure on the end faces of the cylindrical bale is reduced during the unloading process. A large round baler is proposed in which a support structure provided with rolls for supporting one or more flexible bale-forming elements, which can be pivoted about a pivot axle that penetrates the side walls of the baling chamber. At least one side wall is provided with a ramp having an inclined surface which is ramped outwardly from the side wall from top to bottom. The support structure is provided with an abutment member that can slide on the surface of the ramp so as to move from bottom to top when the support structure is raised to effect a discharge of a formed bale. The ramp is maintained in engagement with the abutment member, which travels in a vertical plane, due to outward deflection of the side wall, which results in a decrease of the force applied by the side wall on the bale and the frictional force resisting movement of the bale relative to the wall so as to aid in the discharge of the formed bale from the baling chamber.
