Beschreibung
Zusammenfassung:	The invention relates to a method of manufacturing a heat exchanger tube (2) for a motor vehicle, said tube (2) comprising a strip (10), bent over on itself to define several channels (12a, 12b) for the circulation of fluid, and a perturbator (14a, 14b), situated inside each of the said channels, the method comprising a step of separating a sheet of material along one or more band-cutting lines, situated on each side of said cutting line or lines, so as to define each perturbator (14a, 14b) of said tube (2) from one of said bands.
