Abstract

Um ohne Nacharbeit nach dem Biegevorgang eine einwandfreie Form des Profils, einschliesslich dem Biegebereich, sicher­ zustellen, ist vorgesehen, dass wenigstens der Bereich (3) entlang einem Längsrand auf ein bestimmtes Profil verformt wird, dass danach der Streifen (1) gebogen und eine dabei auftretende Deformation im Profil durch Pressen korrigiert wird, und dass dabei im Biegebereich überschüssig werdendes Streifenmaterial (18) im wesentlichen nach einer Seite weg­ gepresst und danach bündig mit der Längskante des Streifens (1) abgetrennt wird. To a flawless without rework after the bending process Shape of the profile, including the bending area, safely to deliver, it is provided that at least the area (3) deformed along a longitudinal edge to a specific profile is that afterwards the strip (1) is bent and one occurring deformation in the profile corrected by pressing and that there is excess in the bending area Strip material (18) essentially to one side pressed and then flush with the long edge of the strip (1) is separated.
