摘要：
The present disclosure relates to an apparatus and a method for deforming sheet metal plates and more particularly aluminium and steel plates. The objectives of this disclosure are realized by laminating a plate of sheet metal in juxtaposed and parallel strips. This method allows for the formation of spherical surfaces having a variable curvature. These strips are oriented according to predetermined axes according to the expected result.
