摘要： The invention relates to a method for producing a pipe element (1) for pipes that are subject to vibrating stress, especially for exhaust pipes in motor vehicles. Said pipe element consists of a preprofiled strip (2; 3), especially a metal strip, that is wound in convolutions with bellow-shaped windings (4; 22). The wound layers produced by a strip width are interlinked in a single-hooked or multi-layer clasp-type bond (9; 19) by positive locking, welding or similar joining methods. The Strip (2; 3) is preprofiled with at least one stitch that is off-set from the plane by deflection into a kind of circuit with web heights (h1, h2) of the bellows (4; 22) that are multiples of the strip thickness.
