CA 1115917

A B S T R A C T The invention permits the lining of a passageway or pipeline with a resilient but robust, semi-rigid plastics pipe. The invention enables the lining of pipelines and passageways of long length by extruding the lining tube on site, deflecting the tube so that it is deflected into smaller diametral size, holding the tube in the deflected condition, feeding the deflected and held tube into the passageway to be lined, and releasing the hold on the tube so that it deflects or is deflected back to its original form and lines the pipeline or passageway.
