Abstract
L'invenzione si riferisce al settore della tecnica della produzione di apparati flessibili a tenuta per comandi oleo-idro-pneumatici di organi meccanici.Il problema tecnico da risolvere consiste nel fabbricare con un nuovo metodo, pure soggetto del presente trovato, un apparato flessibile comprendente raccordi metallici d'estremità ottenuti modellando a freddo porzioni di metallo costituenti i suoi componenti. L'apparato comprende un tubo (3) flessibile avente all'estremità (c) un manicotto (2) ricavato da un disco (18) metallico circolare, a cui è associato un dado (7) girevole con boccola (8). All'altra estremità (d) del tubo (3) è posto il raccordo (9). Il procedimento di fabbricazione riguarda rispettivamente i raccordi (1) e (9) di estremità (c) e (d) e tutti i suoi componenti, particolarmente ghiera (6), dado (7), boccola (8), dado (10) ed ogni altro.
