Recasting method for structural members involves vibrating tool when extension of structural member has been inserted into tool

摘要

An extension (9) of a structural member is inserted into a tool (22). An engraver (15) inside the tool forms the structural member to produce a new structural member (8) by the vibration between the extension and the tool. The tool is mounted on a slide (7). An independent claim is also included for a recasting device.
