ABSTRACT:
A method for manufacturing long products from a lengthy plate-like material having an appreciably small thickness by press working is disclosed in which the plate-like material is fed in succession into the press working stages of a single press unit carrying out a centering process, a bending process, a coining process, a sizing process, perforating process, and a final shearing process. The material having passed these press working processes is formed into long products having various required lengths and various required number of perforations formed therein. The spacing of the perforations are kept constant irrespective of changes in the thickness and width of the material.
