Abstract
An improved apparatus for forming a tube from a strip or band material, in which the ratio of the thickness of the strip to the diameter of the tube is less than 3%, said apparatus being characterized by: forming means for giving said strip or band material the shape of an open tube, said open tube having a longitudinally extending groove or slit defined by the opposite edges of said open tube, said shaping means being characterized by having a plurality of shaping frames ; and means for joining the opposite edges of said open tube; whose improvement is characterized in that guide means are provided between each of said shaping frames to prevent the opposite edges of said open tube from warping or curling, said guide means touching a surface of said open tube in a substantial part of the distance between each of said forming frames.
