Abstract

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.
