Abstract
846,621. Coiling helically jointed tubes; welding. DE WENDEL & CIE. June 2, 1958 [June 7, 1957], No. 17523/58. Classes 83 (2) and 83 (4). Apparatus for producing tubing from flat strip includes shaping rollers, means for feeding the strip to the shaping rollers at a predetermined angle to the axes of said rollers so that the strip is helically coiled, additional rollers supported to engage the outer surface of the coiled. strip at points lying generally along a helix of a pitch corresponding to the pitch of said helical coil, and means for continuously welding the adjacent edges of the strip to provide a continuous helical welded seam, said welding means being positioned beyond at least part of said additional rollers at a point where the strip material has substantially received its permanent set to the final shape of the tubing. Metal strip 9 fed through a guide 10 to outer rolls 5, 6 and an inner roll 7 is coiled thereby into a tubular helix which is then supported first by a helical series of rollers 12 where it is welded, and then by rollers 21, Fig. 5, on a tilted table 22 which flex the tube upwardly. The rolls 5, 6, 7 and 12 are carried by a tubular member 1 on a base 2 adjustable to vary the angle the incoming strip makes with the tube axis. The roll 6 is adjustable radially and the roll 7 is mounted eccentrically on an end plate 8 rotatable in a circular aperture to adjust the roll 7. Adjacent edges of the wound strip are welded together by an electrode projected through an aperture 16 in the top of the tubular member 1. A fluid-cooled anvil block 17 is spring mounted on the roll 7 to serve as a backing for the strip during welding.
