PCT No. PCT/SE87/00354 Sec. 371 Date Feb. 13, 1989 Sec. 102(e) Date Feb. 13, 1989 PCT Filed Aug. 6, 1987 PCT Pub. No. WO88/01208 PCT Pub. Date Feb. 25, 1988.A machine for corrugating sheet metal or the like comprises a plurality of successive working stations each provided with upper and lower rotatable corrugating devices adapted to jointly provide corrugations of successively increasing depth in a metal sheet (6) which is successively advanced through the machine from a front station toward a rear station. According to the invention, both the upper and the lower corrugating device at each station comprises a plurality of rollers (13, 16) which are individually mounted and thus rotatable at optionally variable peripheral speeds. The rollers (13, 16) preferably are adjustably movable in the direction of their axes of rotation and lockable at desired spaced-apart locations.
