Abstract: Method and apparatus for producing a liner hose (30) for lining channels and pipes, comprising a circumferentially closed inner film hose (32) and at least on fibrous strip (34) wound onto the inner film hose (32) and impregnated with a curable reaction resin, wherein the inner film hose (32) is drawn in a winding apparatus (40) onto a support tube (8) which is mounted on one side and arranged substantially horizontally, at the free end (10) of which a winding mandrel (12) is arranged having a transport apparatus (16) which, during the circumferential winding of the fiber strips (34), transports the inner film hose (32) in a feed direction (36) to a stationary supporting surface (18) which is arranged at the free end (10) of the winding mandrel (12) and over which the liner hose (30) is conveyed further, wherein the inner film hose (32) is drawn over the free end (13) of the winding mandrel (12) onto the support tube (8) against the feed direction (36).

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.
