Abstract
PURPOSE:To ensure the fixture of a side seaming part by forming the uneven ness of a small pitch on a side seaming contact face, mating a bending part thereto, then, executing calking by a pressure fitting roll. CONSTITUTION:A pressure welding race 3 is formed by a knurled roller, etc., on both faces at both side ends of the metal plate 1 formed in a square pipe. In this case, the crest part 3a, root part 3b are formed in a fixed pitch with uniform height and depth as the whole. The pipe main body P subjected to a primary bending and side seam joining is fed to a fixing part 9. The side seaming part H is fed forwards via an upper forming roll 12 and the pressure fitting roll 10 inside a core 10 fixes the part H with its pressure fitting. At this time, the crest part 3a and root part 3b of the mating part are large at their contact area, hence the mating part is surely fixed. Consequently the fixture of the seaming part is ensured.
