Abstract (en)
[origin: WO9106382A1] Described is a folding machine in which a metal sheet is clamped between an upper and a lower clamp, and the section of sheet extending out beyond clamps is bent through a given angle by a bending cheek. During the rotating motion of the bending cheek, it moves into an initial position perpendicular to the axis of rotation. This steers the bending cheek along a given bending contour.
