ABSTRACT:
A circular table is provided around a wire forming portion. A plurality of forming tool units are disposed on the surface of this circular table such that they are directed to almost the central position (wire forming portion) of the table. Each forming tool unit is movable along guide grooves formed in the surface of the circular table, and its position can be fixed. Therefore, the entering direction of the forming tool mounted to the distal end of the forming tool unit can be arbitrarily changed. Independent servo motors are respectively mounted to the forming tool units, and they can be driven independently of each other.
