み(91)を形成して製造できる。2. Description of the Related Art As shown in FIG. 6, there have been proposed various nails (92) having recesses (91) for retaining at equal intervals in a shaft portion. Conventionally, the nail is rubbed by sandwiching a nail (92) between a pair of plate dies (100) and (101) as shown in FIG. 7, or a pair of clamping blocks (102) as shown in FIG. Press the nail (92) with (103) and block (102)
(103) The nail can be manufactured by forming a recess (91) in the nail by the concave and convex grooves (104) and (105) formed on the inner surface.

In the latter case, in a header capable of continuously manufacturing nails from a wire rod, when the tip of the wire rod is hit to form a nail head, a concave-convex groove is formed in a pressure-blocking block that holds the wire rod, and the recess shown in FIG. It is possible to form nails (92) with 91). However, forming a plurality of depressions at once at equal intervals over almost the entire length of the nail requires a large amount of pressing force, and the pressure mechanism is designed so that the required rigidity and durability can be obtained. Then, the size of the header becomes large and the equipment does not match the unit price of the nail.
