PURPOSE: To prevent the generation of flaw on the front surface of tube material by holding both side surfaces of the tube material with the fixed long size shaped material, and driving the traveling unit in the axial direction while connecting the traveling unit with the plate material as the driving force transmitting part to the end of the tube material.
CONSTITUTION: The tube material 9 is set on the L letter shaped material 2, a cover 17 is closed. Each L letter shaped materials 1, 2 hold the tube material 9 from the upper and lower sides. When the motor 20 is driven, chain belts 4, 5 are turned, the traveling unit 3 is advanced through the plate materials 3b, 3c, and transfers forward while pressurizing the tube material 9. The front surface of the long size tube material is not flawed.
