FIELD: municipal engineering. SUBSTANCE: invention concerns facing tubes for repair of inner surface of various-destination pipelines, e.g. those for water and heat supply and sewage. When manufacturing tube, structure elements of reinforcing material needed to form main tube are layered and main tube is impregnated with binder by way of drawing formed tube in the form of flat tape through binder bath. Impregnated main tube is combined with external film tube delivered by means of accumulator. According to invention, before main tube is drawn through binder bath, internal film tube is placed inside the main tube. EFFECT: increased strength. 2 cl, 1 dwg
