    Patent number: 5430928
    Abstract: In order to fix a perforated plate (2) to the bottom (1) of a vessel, the plate is fixed by closed-die forging, in particular by cold striking so as to make the metal of the bottom (1) penetrate into the openings (4) in the plate (2). At the same time as the closed-die forging operation, a series of reliefs (5) is formed on the surface of the perforated plate (2) as well as on the surface of the bottom (1) of the vessel.
