<p>The method involves producing a hollow mark (38) on a side (40) of a plate to be oversized, by a pointing or cutting tool (42) e.g. punch. Depression of the punch causes bulges (44) near the hollow mark, to form overthickness. The bulges are not compressed in a hollow shaped mold. Thickness of the mark is adjusted based on sealing capacity and/or resistance to desired compression. An independent claim is also included for a gasket comprising a plate.</p> |
