Abstract

APPARATUS FOR FORMING METALLIC UNITS

Abstract of the Disclosure Each of the metallic units has a concave portion bounded by a peripheral edge which has a predetermined shape. The apparatus includes an upper member and a lower member and a tool is adapted to be mounted on the upper or lower member. The tool comprises a wall-like structure having a bottom edge which defines a shape corresponding with the predetermined shape. The upper member and lower member are arranged to be movable relative one to the other, and a workpiece is placed between the two members and the members are brought together until the tool is clamped abuts the workpiece so that the tool and workpiece are clamped together in airtight engagement. Air under pressure is applied under the workpiece to form the workpiece into a concave shape.
