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.

Abstract: A tubular liner for rehabilitating sewers includes a circumferentially expandable reinforcing layer impregnated with a light-curable reactive resin, and an outer tubular film surrounding the reinforcing layer and formed of a radially expandable material impermeable to UV light, in particular a liquid-tight and gas-tight plastic film. The tubular liner can be pulled into a sewer to be rehabilitated and can be expanded, in particular by using compressed air, so that the reinforcing layer and the outer tubular film contact the inner wall of the sewer before the reactive resin is cured. A protective tube made of a tear-resistant material is disposed around the outer tubular film and has a connecting portion extending in the longitudinal direction of the outer tubular film and being expandable in the circumferential direction by introducing compressed air into the tubular liner.
