Abstract
For the production of arc elements of disc form a metal strip of wedge form is rolled on edge around an axis of curvature, the metal strip side faces, which converge on one another in wedge form, being rendered parallel. The invention relates to a method for the production of a part-circular arc element the cross-sectional area of which--considered in a section containing the axis of curvature--possesses a, preferably longer, extent in the radial direction and a, preferably shorter, extent in the axial direction and the side faces of which, which are perpendicular to the axis of curvature, are substantially plane-parallel, especially of a check flange for a plain bearing shell.
