PURPOSE:To make it possible to press accurately and continuously the part of the whole length of a tube on the inner surface of a pipe by rotating a roller along the inner surface of the pipe while the tube is spread out by force and at the same time by advancing the roller to the longitudinal direction of the tube. CONSTITUTION:As a roller 160 is rotated along the inner surface 21 of a tube 1 while the tube is spread out of force in contact with the tube 1 and at the same time the roller 160 is advanced to the longitudinal direction of the tube 1, the roller 160 as a result rotates spirally in the tube 1 and the tube is pressed on the inner surface of the tube 1 during this process, where the cylindrical tube 1 being pressed on the inner surface 21 of the tube is successively cured by irradiation with ultraviolet ray from a lamp 190. Even if tears exist in the tube in this case, curing fills the tears. As pressing the tube 1 on the inner surface 21 of the pipe and curing the tube 1 pressed on the inner surface 21 of the pipe are carried out in parallel, the lining of the inner surface of the pipe body 2 is efficiently carried out. |
