To provide a method for taking up a thermoplastic resin liner material on a take-up bobbin for restraining breakage of the substantially U-shaped liner material while being taken up, and preventing the liner material from being ruptured during lining regeneration of an aged pipe.

When taking up the substantially U-shaped liner material, which is obtained by radially pressing a thermoplastic pipe from a pipe surface along a pipe axis and having it bent and recessed to be deformed into a substantially U shape, on the tale-up bobbin, a surface temperature of the substantially U-shaped liner material is maintained at a temperature between -25 to +10°C of a secondary transition temperature of a polyvinyl chloride based resin.
