Abstract:
The present invention refers to a method of producing a tubular lining ho in particular for use in sewer reconstruction work, comprising the steps of forming at least one fibrous strip into a curable, resin-impreganted hose. The inner side of the resultant lining hose is provided with a protective foil. It is the object of the present invention to provide a method of producing a tubular lining hose with the aid of which hoses of arbitrary length can be produced in a simple manner. This object is achieved by producing first a foil hose, which forms the protective foil, by helically winding a foil strip onto a winding mandrel, the fibrous strip being then wound onto said foil hose. In addition, the present invention refers to apparatuses for carrying out said method as well as to the lining hose itself.
