Abstract

PURPOSE:To form a hook easily at the tip of a lead wire by forming a concave in a lead wire when it is pressed, and bending the concave. CONSTITUTION:The tip of a lead wire 31 is crushed by pressing. A projection 34 installed in a press moled 33 is pressed to the lead wire 31 to form a concave 36 on one side of a crushed part 35 of the lead wire 31 crushed flatly. An anvil 37 is placed to one side of the lead wire 31, so that a pointed end 38 of the anvil 37 is positioned at one end of the concave 36, and the lead wire 31 is bent by a bending arm 39 to form a hook 40.
