IMPROVEMENTS RELATING TO LINING MATERIALS CONTAINING CURABLE RESINS

摘要

Lining tube material including a curable latent resin system for lining underground pipelines and passageways is prepared as a large supply (10). Measured lengths (20) are taken from the supply (10) 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 (22) 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.
