Abstract

A tool for producing bends or steps in curved surfaces has an upper and a lower tool part arranged to work towards one another when in operation. The tool part surfaces conform in shape with the curved surface in which one or more bends are to be formed. The tool part surfaces are made as form tools resiliently mounted and guided in the upper and lower tool parts. The form tools also identify in shape with the original curved surface. The inventive tool is suitably arranged in a press.
