Abstract

See full text

An upper die with a button-mounting member includes a solid axial part with a flat tip, a bar-like pin member with a pointed tip, and a cylindrical punch surrounding the pin member. The button is set above the cloth and the button-mounting member is disposed below the cloth. The upper die is lowered until the button comes into contact with the upper side of the cloth and the tip of the axial part contacts the lower side of the cloth. The pin member is lowered until the tip hits against the tip of the axial part, resulting in a pilot bore through the cloth. The axial part passes through the cloth along the pilot bore and through the mounting opening. After that, the axial part is swaged by the pin member and the punch.
