(Reference) In the T-shaped cross section 16 in the vicinity, a green base piece 17 is attached to a steel wire 18 such as a piano wire attached to the bottom mold 13.
It is suspended from the tip of the. Figure 3 shows the raw material
This is an enlarged view of the surrounding area, and the raw material piece 17 is sufficiently smaller than the widths W1 and W2 of the cavity 15.
