A liner tube () for rehabilitating sewers and water drainage ducts, with an inner film tube (), a first layer () arranged thereon made of nonwoven material, and a second layer () made of glass fiber material and arranged on the layer () made of nonwoven material, is characterized in that the first layer () contains at least one overlapping wound strip made of nonwoven material, which is impregnated with a fluid reaction resin which can be cured by light or heat, and in that the second layer () contains at least one first strip () which is impregnated with a fluid reaction resin and made of glass fiber material, which has glass fibers () extending in the longitudinal direction of the liner tube. The invention furthermore relates to a method for producing a liner tube of this kind.

Liner tube for sewer rehabilitation and method for producing same

A method for producing a liner hose () for lining pipelines, comprising the method steps of moving a circumferentially closed inner film hose () over a winding mandrel () of a winding apparatus () and wrapping the inner film hose (), which is guided on the winding mandrel () by means of a guide mechanism (), with a fibrous strip () which has been impregnated with curable reaction resin, is characterized in that the inner film hose () is guided via endless pulling means () that circulate without a drive, and in that the inner film hose () that has been wrapped with the fibrous strip () is moved off of the winding mandrel () solely by a pull-off mechanism () which acts from the outside on the fibrous strip (). The invention further relates to a device for carrying out the method.

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

A winding mandrel () in a winding apparatus for producing a liner hose () for the lining of channels and pipelines, which comprises an inner film hose () and a layer arranged thereon made of at least one fibrous strip () wound in an overlapping manner, which is impregnated with a liquid reaction resin, with a base body (), on which at least two guide mechanisms () are accommodated, each comprising a continually circulating belt (), by means of which the inner film hose () is moved in a feed direction (A), is characterized in that the first guide mechanism () is coupled by fixed mounting to the base body (), and in that the circulating belt () of the second guide mechanism () can be moved in a plane extending perpendicularly to the feed direction (A) and is forced away from the upper side of the base body () by means of pressing means () with a preferably substantially constant force.
