Abstract
Ved, en fremgangsmåte for fremstilling av dlafragmer, påføres et sjikt av et tungt rlsledyktlg netallpulver på et underlag, et trådnett påvalses på pulversjlktet ved samtidig fortetning og netallpulveret brennes l oks l eierende atmosfære ved 800 til 1500'C. For å oppnå konstant tykkelse, fasthet og tetthet for diafragmene, tildeles og påføres metallpulveret jevnt Ifølge rystevoluaer på underlaget og pulversjlktet føres gjennom under en fordelervalse(5)som roterer motsatt pulverets tildelIngsretnlng.
