Abstract
Oppfinnelsen vedrører en fremgangsmåte og apparat for fremstilling av et kokekar, så som en stekepanne (12) eller en kjele, av et metallemne. Ifølge oppfinnelsen tilvirkes kokekaret ved rollformingsteknikker under anvendelse av et nedre verktøy (3), som roterer om sin akse (2), idet formflaten (6, 7) av det nedre verktøy er utformet slik at den tilsvarer den ytre flate av det fremstilte kar, og et øvre verktøy (5) som roterer om sin egen, separate akse (4), der profilen av den øvre verktøyflate (9, 10) tilsvarer den indre flate som formes på karet. Emnet plasseres på formflaten av det nedre verktøy, og verktøyene bringes deretter (3, 5) til å rotere slik at emnet roteres sammen med det nedre verktøy og flaten av det øvre verktøy er i lineær valsekontakt med emnet, hvorved metallet omformes i mellomrommet mellom verktøyene, idet metallet spres ut til den ønskede form av karet. Ved fremstillingen av stekepannen (12) kan emnet være et plateliknende metallstykke, hvorved pannens stigende kanter dannes under rollformingen ved at emnet sprer seg radielt utover ved sine kanter. I forbindelse med formningen kan inner- og ytterflaten utstyres med mønstre som består av fremspring og/eller forsenkninger.
