摘要： A liner hose for use in the reconstruction of damaged buried conduits or pipelines, in particular sewers, comprises inner and outer layers of liquid-tight plastic film material and a number of substantially uniform intermediate layers composed at least partially of a fibrous material impregnated with a curable resin. Each intermediate layer is formed from a strip, which is substantially unstretchable in any direction and has a width such as to enable folding of the strip into a closed hose structure with unbonded seamless overlapping. The overlap sections of all intermediate layers are located with mutual separation in the same side of the liner in its folded condition. The liner hose is manufacture by arranging a number of said strips into a sandwich configuration with the inner calibration hose with the strips overlapping each other with a mutual substantially uniform displacement, so that the total separation of longitudinal edges of lower and upper strips is less than half the width of each strip, and folding the sandwich configuration in one operation around the inner hose.
