ABSTRACT:
A device for the bending and deformation of panels such as skin elements for covering cells of vehicles in the aerospace industry such as aircraft, rocket space vehicles or the like, the skin elements having inwardly directed stiffening ribs which intersect in nodes; the device has first and second deforming members being capable of engaging the skin element in points adjacent to nodes under consideration of length changes obtained by some of the ribs; the two deforming members are adjustable in relation to each other and other through a variable armature mount such that the deforming forces respectively provided into the part to be deformed are oriented in the area of the nodes transversely or nearly transversely to those ribs which extend transversely to the curvature to be obtained and consistently tangentially to the panel part in the direction of curvature and following change of curvature on account of bending; and the direction of force action as provided by the deforming members into the work part is varied such that these forces as provided by the two deforming members do not have to act coaxially in relation to each other.
