Abstract: The present invention relates to an apparatus and a system for curing a liner extending in a pipeline or at least in part in a branch pipeline, where the liner includes a substance such as a synthetic resin suitable for being curable by exposure to electromagnetic radiation. The apparatus comprises an actuator constituting an electric, hydraulic or pneumatic actuator, and including an actuator member and an actuator axis substantially parallel to the axis of the pipeline when said apparatus is in its intended operational position in said main pipeline.

Abstract: A system for repairing an underground pipeline using a light source. A resin soaked tubular liner is inverted within an underground liner. A tubular bladder is subsequently inflated within the tubular liner. A pull line is attached to a free end of the bladder. The light source is attached to the pull line. The bladder pulls with the pull line and light source into the liner as the bladder is inverted within the liner. The light source is subsequently activated and separated from the pull line. The light source is then pulled through the bladder and liner, curing the liner as it moves.
