Abstract

A tubular liner for the lining of pipelines has an inner tubular film, a layer of fibrous material arranged on the inner tubular film, and an outer tubular film which is arranged on the outer side of the fibrous material and is impermeable to UV light. The tubular liner is distinguished in that the outer tubular film has a radially inward peripheral portion and a second peripheral portion bearing on the outer side of the first peripheral portion in an overlapping region. The peripheral portions are connected to one another by an adhesive tape which extends across the longitudinal direction of the tubular liner. A method is also provided for manufacturing such a tubular liner.
