Abstract

Zum Anbringen von Laschen (13, 14) oder Vorsprüngen an einem Feinblech wird vorgesehen, daß diese Laschen und/oder Vorsprünge mittels Massivumformens aus dem Feinblech heraus geformt werden. Ein derartiges Feinblech wird in Form eines Feinblechstreifens bevorzugt zum Bilden von Rechteckrohren für einen Abgaswärmetauscher eingesetzt, der zur Führung des Abgases mit einem Bündel aus diesen Rechteckrohren versehen ist.

Figure 00000001
To attach tabs (13, 14) or protrusions to a thin sheet, it is provided that these tabs and / or protrusions are formed out of the thin sheet by means of massive forming. Such a thin sheet is preferably used in the form of a thin sheet strip to form rectangular tubes for an exhaust gas heat exchanger, which is provided with a bundle of these rectangular tubes for guiding the exhaust gas.
