  • Patent number: 4788900
    Abstract: A round bale press for agricultural stalk material which has a housing defining a pressing chamber with variable volume. The pressing chamber is defined by opposed side walls of the housing and at least one continuous belt within the chamber. The belt is guided by a plurality of cylindrical rollers. At least one stripping device is attached to the housing adjacent one of the rollers which is adjacent to the feeding area. The stripping device consists of a rail with supporting plates on both end sections. On said rail a steel knife blade is mounted for contacting the surface of the roller with uniform contact pressure over the longitudinal extension of the roller surface. At least one clamping device is integrated into the stripping device which is actuatable from outside the housing side walls for bending a central section of the rail relative to the end sections of said rail. A uniform contact pressure between the knife blade and the surface of the roller is achieved.
