Abstract

Process for the manufacture of double-walled tubes, in particular curved exhaust pipes, with an annular air gap between the outer tube and the inner tube, characterized in that the two tubes, first carried to the intended length, are interconnected and fixed in each other. At least one point, and then placed, on the two cores of a bending device in such a way that, during the bending operation, separation means are formed by stamping on the outer tube, for example in the form of protrusions of longitudinal and transverse ribs.
