    摘要： Thin-walled materials are stiffened by bulging without causing material deformations typical of deep-drawing. A material web to be structured with bulges is wound in several layers around spaced apart supporting elements (2), the material web winding (1) is outwardly sealed by hydraulic means and an overpressure is applied thereto from the outside and/or a negative pressure is applied thereto from the inside. Alternatively, a material web to be structured with bulges is bent on spaced apart supporting elements (34) and an overpressure is successively applied thereto from the outside or a negative pressure is successively applied thereto from the inside, in particular segment by segment.
