A process for the manufacture of cooking vessels, in particular pots and/or pans in a relatively soft metallic material, with a plate in a metallic material of high hardness applied to the bottom of the vessel, performs a stable connection among said parts with no mechanical and/or thermal trauma for the materials and comprises the steps of: providing a plate (1) provided with a plurality of points (6) projecting from a surface (4) thereof; inducing, by compression, the penetration of said points (6) and the adhering of said surface (4) at the bottom (20); and stretching said bottom (20), thereby causing the deformation and the clutching of said points (6).
Cette invention se rapporte à un procédé servant à fabriquer des récipients de cuisson, tels que notamment des casseroles, dans un matériau métallique relativement mou, une plaque en matériau métallique de dureté élevée étant appliquée au fond de ce récipient, ledit procédé permettant un assemblage stable entre ces parties sans dommages mécaniques et/ou thermiques causés aux matériaux. Ledit procédé consiste à cet effet: à prendre une plaque (1) pourvue de plusieurs pointes (6) faisant saillie à partir d'une de ces surfaces (4); à induire, par compression, la pénétration de ces pointes (6) et l'adhésion de la surface (4) au fond (20) du récipient; et à étirer ce fond (20), afin d'entraîner la déformation et le serrage desdites pointes (6).
