Method for producing a liner hose for lining pipes and apparatus for carrying out the method

An apparatus for producing a liner hose comprising:

• a winding mandrel extending longitudinally from a proximal end to a distal end, the winding mandrel having a guide mechanism extending longitudinally along the winding mandrel and substantially parallel with a surface of the winding mandrel, the guide mechanism being adapted to receive and engage an inner surface of an inner film hose, wherein the guide mechanism comprises an endlessly circulating, free-running, non-driven belt extending longitudinally and substantially parallel to the surface of the winding mandrel, and wherein the belt is supported by a plurality of guide rollers wherein all of the guide rollers are free-running, non-driven guide rollers;
• a winding apparatus radially spaced from the winding mandrel and adapted to rotate about the winding mandrel and wind at least one fibrous strip impregnated with a curable reaction resin onto the inner film hose to form a liner hose;
• and
• a pull-off mechanism longitudinally spaced from the distal end of the guide mechanism, the pull-off mechanism having at least one driven roller or belt adapted to engage an exterior surface of the liner hose, and wherein the driven roller or belt rotates in a direction to pull the liner hose over the winding mandrel and guide mechanism.
