PURPOSE:To improve the productivity of a cold pressed article without the need for refining after working by performing an annealing with heating as well as performing a tempering of a wire rod material on the way of its feeding to a former, and executing the cutting and cold pressing in successionon in order at the warm zone. CONSTITUTION:A tempering device 10 and annealing device 15 are composed of the heater 11 and cooler 12 like a high frequency heating device or resistance heater, a wire rod W is heated to the tempering temp. By the heater 11 and a tempering is performed by acting it inside the cooler 12 immediately thereafter. The annealing device 15 has an adjuster 16, performing the cutting and cold pressing of a blank at the worm zone of this temp. By heating the tempered wire rod to the annealing temp.
