ABSTRACT:
A tool assembly 120 is attached on a forming table 101 movably in a vertical direction with respect to the forming table 101. The tool assembly 120 has a wedge tool assembly 140 which inserts a wedge tool between coils of wire W being continuously rolled by a coiling assembly 160 and growing coils having a predetermined pitch in an approximate normal-line direction with respect to the forming table 101, and a core block 123 which applies a cutting force to the wire W in cooperation with a cutting tool. This integrally moves the core block 123, the wedge tool and the like.
