Abstract

L'invention se rapporte à un appareil et à un procédé servant à fabriquer un organe de fixation de chemin de fer. Lors de la fabrication, on place une partie médiane 3 d'une tige d'acier chauffée au rouge dans un étau 16 et on actionne deux organes de cintrage 21, 22 pour venir courber la tige de part et d'autre de la partie 3 autour de surfaces de formage 12, 13 pour produire deux coudes, ceci sensiblement sans déplacement de la partie 3. Les deux parties terminales 1, 5 de la tige se trouvent alors être tournées en des directions sensiblement opposées et se chevauchent sans se toucher.
