摘要： The invention concerns an arrangement for shaping a helical pipe (18), said arrangement comprising a first stamping station for producing a flange on a metal strip (11). In a shaping tool (17) the metal strip is flanged at the side edges and cut into predetermined lengths by a subsequent cutting arrangement (19). In order to determine the length of the helical pipe (18) to be cut, a mechanical-optoelectronic measuring arrangement (20) is provided.
