Zusammenfassung:PURPOSE:To perform a series of stages for flux cored wires continuously and to improve productivity by packing a flux in a tube while subjecting the seam of a steel hoop formed to a tubular shape to induction welding and drawing the tube. CONSTITUTION:A belt-like wire W1 is supplied from a storage part, and is run in parallel in the part of guiding rolls 1. After the direction is changed to a downward inclining direction by a guiding roll 2, the wire is formed to a semi- circular wire W2 by curving rolls 3. Further, while the wire is formed to a tubular shape by means of tube forming rolls 4, the seam right after the same is welded with an induction coil 5 and a nozzle extending from the bottom end of a hopper 6 is inserted into the formed tube and a flux is sprayed and packed therein from the nozzle. The tube is passed through squeezing rolls 7, and if necessary, the tube is passed through a deburring device for the induction weld zones; thereafter, the tube is conducted to a die 8, by which the tube is drawn to a prescribed size and the product is obtained.
