ABSTRACT:
Disclosed herein a method for forming plates into shapes having a double-curved surface, and an apparatus for carrying out the method. For forming a double-curved plate, a work is three-dimensionally formed by passing same through an entrance roll, flexible rolls and exit rolls which are in vertically adjusted positions relative to each other. The flexible rolls are constituted by a pair of flexible and contractibly extensible upper and lower rolls which are supported in flexed state by a plural number of bearings to define therebetween a desired bending shape. As the work is gripped between and fed through the two flexible rolls, it is imparted with a deformation across its width. Therefore, the bending form of the work can be preset by controlling the vertical positions of the bearings which support the flexible rolls, making it possible to form a double-curved plate by a simple control involving a reduced number of control points.
