Abstract (en)
[origin: EP0457358A2] The invention describes a method and an apparatus for spinning a metal blank to give a curved shaped part, in particular a container base. With the method and apparatus, even those materials which are difficult to form can be formed with dimensional accuracy and/or with high degrees of deformation. For this purpose, it is proposed to grip the blank at the periphery and to curve it freely, i.e. without the use of a spinning chock, into a free space (4) to the final dimensions with the aid of a motion-controlled spinning tool (3). <IMAGE>
