Abstract

PURPOSE: To attach the tubular protecting film to the inner wall of the tube with good workability by enclosing and folding the tubular protecting film to be attached in a pressure box in a bellow shape, applying bonding agent in the inside of the film, and by giving pressure to the outside of the tubular protecting film.
CONSTITUTION: The protecting film 1 comprising a soft resilient tube is folded in a bellow shape and enclosed in the pressure box 2. One end of the film 1 is fixed to the tip of a contact part 25 which contacts with a tube-to-be-treated (a) which is provided at the end wall 22 of the pressure box 2. The other end is intimately contacted with the other end of the pressure box 2. The bonding agent is applied to the inside of the protecting film 1 from the other end of the film 1, and the pressure is applied in the pressure box 2. The bonding agent is applied to the inside of the soft resilient tube 1 which is the protecting tube, and the tube 1 is pushed into the inside of the tube-to-be-treated (a) from the contact part 25. Immediately before the tube 1 is attached to the inside wall of the tube (a), tube 1 is turned over, and the surface on which the bonding agent is applied is attached and bonded to the inner wall of the tube (a).
