PROCEDE D'ASSEMBLAGE DE MATERIAUX ET ORGANE DE RIVETAGE POUR SA MISE EN ÓOEUVRE.

摘要

A method for assembling materials using a riveting device of the kind which comprises a plug (2) and a sleeve (1). The sleeve (1) is provided on its outer surface with a peripheral recess, in particular a groove (5), in order to form a folding zone, while the plug (2) has a head (9) which can deform the tubular end of the sleeve and fold it back in the folding zone. During riveting, the sleeve's peripheral recess protects the start point of the countersink of the materials from stress and folding said sleeve results in a large bearing surface in perfect contact with the materials.
