Adjustable blade support for round bale press stripper

A round bale press for agricultural stalk material comprising a pressing chamber with variable volume which is defined by a housing and by at least one continuous belt, said housing comprising two opposed housing side walls, said belt is guided by a plurality of cylindrical rollers, at least one stripping device connected to said housing adjacent to one of said rollers, said stripping device consisting of a support containing a rail having a central section and first and second end sections carrying supporting plates, a long spring steel knife blade fastened to the rail, said supporting plates being pivotally mounted between said housing side walls about an axis lying parallel to the longitudinal axis of the support, said support plates being adjustably connected to an adjusting means for adjustment of their angular position in order to have a contact between the knife blade and the surface of the roller, wherein the contact pressure of the blade edge on the roller surface can be made uniform over the longitudinal extension of the knife blade by the convex bending of the rail with its knife blade towards the surface of the roller, characterized in that for the bending of the rail there is provided at least one clamping device which can be actuated from outside the housing side walls and that by means of said clamping device the central section of the rail can be bent relatively to the end sections of the rail towards the surface of the roller.
