Abstract

Fremgangsmåte og anordning for tildanning av en rektangulær krage i enden av et rar (34) ved utforming av rørenden ved hjelp av et formingselement (1) som beveges i rorets aksial- retning mot røret og dreies langs rørendens innervegg om rørets lengdeakse. Formingskonusen (1) beveges i rørets aksialretning mot røret hvorved den, under sin bevegelse mot røret, dreies automatisk fra en utgangsstilling til en slutt- stilling grunnet trykket som frembringer bevegelsen, under samtidig utforming av rørenden til en krage som er stort sett rektangulær i forhold til rørets lengdeakseretning.
