A device for feeding material in the form of a coil of wire from a fixture for receiving and rotating said coil of wire through a straightening apparatus and a heating station to a hot and semi-cold metal-working machine in an intermittent manner. The device includes a cold feeding fixture with one or more pair of rollers which act on the cold wire to pull the wire from the coil and through the straightening apparatus and a hot feeding fixture downstream of the heating station with at least one pair of feed rollers which act on the hot wire and urge the hot wire against a stop of the metal-working machine. The device also includes adjustable link means for driving both feeding fixtures in formulant synchronism with the metal-working machine.
