Abstract
PURPOSE:To stabilize the fixture of a side seaming part by joining by forming a pressure fitting part and the non-pressure part not subjected to pressure weld ing alternately in the length direction of the side seaming part. CONSTITUTION:A core 5 is fixed to the tip of the rod 7 projected from a supporting body to support a press-fitting roll 8 freely turnably in the inner part. On the roll 8, the guide plates 8a, 8b regulating the width and height of the side seaming part H are provided and the recessed places 9, 9 having a step difference at equal intervals are formed. When the part H of the pipe main body reaches a fixing part 3, an upper forming roll 10 moves the part H forwards and the press-fitting roll 8 forms a pressure fitting part I and non- pressure part J in order. Therefore, the slippage in the pipe longitudinal direc tion is prevented by the inner part projection of the pressure-fitting part I and non-pressure part J. Consequently the fixture of the part H is stabilized.
