Abstract: In a machine for manufacturing spiral seam piping from strip metal, using a set of three forming rolls consisting of a large number of individual bending rollers, the bending rollers acting on the inside of the pipe being arranged on a roller carrier which is capable of adjustment, the roller carrier (22) is controlled and driven in order to tilt it laterally by the use of a parallelogram control arm system (23) with two control arms (25, 26) arranged in a first control circle plane (24a) and one control arm (27) arranged in a second control circle plane (24b), at least one control circle adjuster (28, 29) associated with a control circle plane (24a, 24b), a link rod (31) acting in the direction of the pipe centerline (30), a lifting device (33) pivoted at the end (32) of the roller carrier (22), and a height-adjustable mounting (34) with a joint plate (36) carried in a bearing in the central portion of the roller carrier (22), a double lever (37) and a lifting device (38).
