Abstract

PURPOSE:To make the promotion of cost down, by making a padding work simply and correctly operable to the required portion, and not operating the padding work to unnecessary portion as conventionally made. CONSTITUTION:Unnecessary portion of a flat plate base material R, being carried to be fed, is cut off by a side cut punch 8, then to a required end edge N of the base material R, is constructed a pad portion M by a padding punch 9. This base material R is cut to a prescribed length by a cutter K, and fed to within a mold metal and processed a forming into a prescribed shape. In this method, the padding work following after the side cut operation being simultaneously performable, with only enough required portion processed a padding work after cutting the unnecessary portion, the work of padding can be fully made even by a press of small power.
