  • Method and apparatus for the manufacture of powder-filled steel tube from steel strip
    Patent number: 4811889
    Abstract: In a method for the continuous manufacture of powder-filled steel tube from steel strip, wherein the strip is moved along a path in which successively the moving strip is formed into an open channel, powder is introduced into the open channel, and the channel is shaped into a tube by further deformation and closure of the strip edges together. To avoid the disturbance of the powder by air currents caused by the strip movement and by the closure of the strip, such air currents arising in the vicinity of the moving strip are removed by suction extraction at the location where the powder is introduced into the open channel.
