Abstract (en)
[origin: EP0822298A2] The edge of the metal plate frame (2), parallel to the top side of the work surface (20), is bent over downwards and inwards to form a curved, peripheral outer rim (12). The frame is placed by its outer rim onto the work surface. The curved piece is pressed flat into at least one smooth surface (15,16). The end edge of the metal plate is also pressed in. At the same time as the pressing process, the transition part between the outer edge of the frame and the top surface (10) is shaped into an outward curved surface, or into a sloping smooth surface (11) of between 15 and 75 deg.
