Abstract

1,039,409. Making tubes from strip, angular bending, welding by pressure. LORRAINEESCAUT. Aug. 4, 1964 [July 29, 1963], No. 30876/64. Headings B3A, B3E and B3R. Apparatus for the continuous production of seamed metal tubes comprises means feeding a metal band to a cutting location, where it is cut into a plurality of strips positioning means locating the strips in spaced relationship and forming means associated with each strip. Prior to passing to the forming means, alternate strips are preferably turned over so that the burrs formed by cutting all face the same way. The forming means shown forms three tubes simultaneously by conventional methods, but the forming rollers G2 for the middle strip are offset longitudinally from the pairs of rollers G1, G3 to reduce the width of the apparatus. Guides 9a, welding rollers S1, S2, 53 and, weld trimmers 11, 12, 13 are similarly offset. High-frequency current may be supplied by contact or inductively. The formed tubes are passed through a cooling unit to a number of straightening units and finally to a cutting unit.
