Abstract

A die apparatus includes a tip end part blanking punch which forms a tip end configuration of a belt-shaped sheet through a punch holding unit in an upper die. The punch holding unit includes a punch plate which holds the tip end part blanking punch, a punch plate moving mechanism which is lowered together with the upper die in a state where the punch plate is separated from the upper die when the tip end configuration of the belt-shaped sheet is formed, and holds the punch plate in a state where the punch plate is allowed to come near to the upper die when the punch plate is lifted, and an actuating mechanism which operates the punch plate moving mechanism in cooperation with a blanking or stamping operation of the upper die only when the tip end configuration of the belt-shaped sheet is formed.
