AUSKLEIDUNGSSCHLAUCH ZUR SANIERUNG VON DEFEKTEN KANALROHREN
The invention relates to a lining tube (1) for restructuring of a defective sewer pipe (100), comprising an inner film tube (10) and a radially expandable layer (20) of at least one overlapping helically wound fibre strip (22) which is disposed around said inner film tube and is plastically extendable in the longitudinal direction by a tensile stress acting thereon in an extension region (D), characterised in that the fibre strip (22) comprises extension limiting means (100), which actively limit further plastic rotation of the fibre strip (22) in the extension region (D) in the longitudinal direction when an extension limiting value (G) determined by the extension limiting means (100) is exceeded.
