摘要： Method for bending a corrugated plate about an axis extending transversally to the valleys and crests respectively, by applying said plate between two press beams the opposite faces of which are provided with mutually corresponding and also with the crests and valleys of the plate corresponding alternating raised portions and recesses, and by then bringing the press beams together so as to press inwardly directed ribs into the bottoms of the valleys and pressing outwardly directed bulges into the adjacent sidewalls of said valleys, in such a way that in the first stage, in which the plate as seen in the longitudinal direction of the crests and valleys is supported through a length which is a multiple of the width of the ribs to be formed, the bulges are pressed only, while the ribs are formed in the subsequent stage.
