Abstract (en)
[origin: EP0299948A2] A method and a device for making two- or multi-layer composite rods from cylindrical workpieces or feedstock bodies having concentrically arranged layers of different materials using tools acting simultaneously on the workpiece in a plane perpendicular to the rod axis, in particular striking or pressing tools which deform the said workpiece. According to the invention, the workpiece is subjected to a progressive deformation over its length, in the deformation zone of the tools, which have at least one section with a conical working face. In the process of deformation, at least one (circular) truncated cone is formed.
