摘要： A method for smoothly evaginating a tubular material under pressure, if necessary, within a pipe line with simultaneous bonding the evaginated tubular material onto the inner surface of the pipe line, which comprises placing in a pressure container having a discharge pipe a part or whole of a tubular material, if necessary, with one terminal end thereof being connected to a first like material rope having a length at least equal to that of the tubular material, if necessary forming a reservoir of a binder enclosed in the interior of the tubular material placed in the pressure container to apply the binder onto the inner surface of the tubular material, fixing the other open terminal end in evaginated state to an annular fastener of said discharge pipe, and applying a pressurized fluid to the pressure container to evaginate the tubular material over its full length as it is propelled from the discharge pipe and, if necessary, moved forward within the pipe line and at the same time bonding the evaginated tubular material onto the inner surface of the pipe line with the binder being interposed therebetween, characterized in that a second rope-like material previously passed through said tubular lining material beyond its full length is drawn out while applying said pressurized fluid. This method is effective for overcoming drawbacks seen in the conventional methods for evaginating tubular materials and is advantageously utilized for the lining treatment of extremely long pipe lines or pipe lines with a number of curved portions without damaging the apparatus and/or lining materials and narrowing the flow path.
