A tube liner (1) for lining pipelines comprises an inner film tube (2), an outer film tube (3) and, arranged in between, a layer of fibre material (4) impregnated with a curable material, wherein at least one of the two film tubes (2, 3) is formed by at least one tube web (5; 51, 52), which comprises a carrier film (6) and a fleece layer (7), which has been applied to the side of the carrier film (6) that is facing the layer of fibre material (4), and the web edges (5a, 5b) of which that overlap one another in the circumferential direction of the tube are connected to one another. According to the invention, the web edge (5a) facing away from the layer of fibre material (4) is formed in the overlapping region (8) only by the carrier film (6), which in the overlapping region (8) projects beyond the fleece layer (7) and in the overlapping region (8) is adhesively bonded or welded directly to the carrier film (6) of the web edge (5b) facing the layer of fibre material (4). |
