Abstract: PURPOSE:To improve reliability and operating efficiency in operation as compared with a restricting method by winding-up of a tape, by holding a form of a lining tube at the time of pulling into a pipe by restricting the form with a gathering ring. CONSTITUTION:A lining tube 1 whose cross section is circular is wound round a drum 5 under a state where the lining is flat or folded in two further, and carried into the spot. The lining tube 1 folded in two is passed through an adhesive agent coating tank 6 by spreading flat once at the time of rewinding from a drum, to the surface of which an adhesive agent 2 such as an epoxy is applied, which is folded in two again and pulled into a pipe path 4 by a winch 7. In this instance, gathering rings 3 made of hot-melt resin are outserted in order over the tube 1 folded in two at such intervals as to not restoring the tube 1 to the original cross-sectional form. When the tube is swollen round by air pressure after completion of pulling-in, expansion of the diameter of the gathering ring 3 is performed by extending the same. Then the ring 3 is melted by heat of steam which is introduced for heating and pressurizing of the tube, united with the adhesive agent 2 and stuck to the inside of the pipe path 4.
