Abstract

Small diameter metal tubes are manufactured with good precision and high production efficiency by using a large diameter roll in which rolls having diameters that are clearly larger than the outer diameter of the metal tube being manufactured are disposed. A pair of large diameter side rolls is used the rolls being designed so that the outer diameter ratio f/ f of the outer diameter f of the forming roll to the outer diameter f of the metal tube being manufactured is 10 or more preferably 25 or more. After forming a metal band into a cylindrical shape in a single stand the edges of the metal band are brought together and welded. A three roll type or a four roll type can be used for the large diameter side roll.
