Abstract of the Disclosure A method for providing the inner surface of a pipe line with a tubular lining material through a binder under fluid pressure which comprises the steps of introducing a tubular lining material in flattened state containing a binder in the interior space thereof in-to a pressure container from a rear end portion thereof, annularly fixing one end of the tubular lining material to a front end portion of the pressure container, applying fluid pressure -to the pressure container for internally pushing the portion of the tubular lining mat- erial in rear of the annularly fixed position to form a turn- ing point where the tubular lining material is turned inside out, and allowing the turning point to advance within a pipe line while bonding the evaginated tubular lining material onto the inner surface of the pipe line by the aid of the binder under fluid pressure, characterized in that the step of intro- ducing the tubular lining material into the pressure container is performed by squeezing the flattened tubular lining material at definite intervals linearly in the transverse direction to the advancing tubular lining material under atmospheric pressure to isolate the portion of the tubular lining material together with the binder contained therein between the adjacent two linearly squeezed positions, allowing the tubular lining material to advance into the pressure container while keeping the tubular lining material squeezed linearly in the transverse direction at definite intervals, and thereafter releasing the tubular lining material from squeezing in the pressure contain- er under fluid pressure.
