Abstract
Lining tube material including a curable latent resin system for lining underground pipelines and passageways is prepared as a large supply. Measured lengths are taken from the supply as needed by measuring the length (for a particular length of passageway to be lined) followed by curing the resin of the material along a short section between the length and the remainder of the supply, and by cutting through the cured section to sever the length from the remainder of the supply leaving a cured and sealing end portion on said length by which the insertion of the length in the pipeline or passageway can be controlled.
