ABSTRACT A machine for corrugating sheet metal or the like comprises a plurality of successive working sta- tions each provided with upper and lower rotatable corrugating devices adapted to jointly provide corru- gations 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 lo- cations.
