Abstract

POSTUPAK I UREDJAJ ZA FORMIRANJE LIMENE PLOČE - NAROČITO ZA IZRADU MASKE KATODNE CEVI, pronalazak se odnosi na postupak i uredjaj za formiranje limene ploče (1), osobito za izradu maske katodne cevi, na presi, prema kome se periferni deo (1b) limene ploče (1) drži na maloj širini u perifernom stezaču (30) i formira prema datoj zakrivljenosti centralni deo limene ploče (1) deformisanjem patrice (17) i matrice (13) pod dejstvom gornje podloge (19) i dejstvuje na lokalizovane zone stezača (30) mehaničkom akcijom, približujući suprotne elemente stezača (30) a istovremeno se priljubljuje i razvija periferna zona limene ploče (1) duž bočnih zidova patrice (17) relativnim pomeranjem stezača (30) u odnosu na patricu (17) ili matricu (13), da bi se dobila definitivna oborena ivica. Predmet pronalaska je isto tako i maska katodne cevi načinjena ovim postupkom.
