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.

[ I claim:] [1.] A method of producing a tubular lining hose (20, 108), comprising the steps of forming at least one fibrous strip (25, 106) into a curable, resin-impregnated hose, an inner side of the resultant lining hose (20, 108) being provided with an inner foil hose (26, 107) onto which the fi
[ I claim:] [1.] A method of producing a tubular lining hose (20, 108), comprising the steps of forming at least one fibrous strip (25, 106) into a curable, resin-impregnated hose, an inner side of the resultant lining hose (20, 108) being provided with an inner foil hose (26, 107) onto which the fibrous strip (25, 106) is wound,wherein a winding operation takes place on a winding mandrel (1) consisting of at least two winding fingers (28), which are arranged essentially parallel to each other and a distance of which can be adjusted in a direction radial to an axis (4) of the winding mandrel (1) so as to vary a winding circumference of said winding mandrel (1), and wherein the lining hose (20, 108) is advanced in a longitudinal direction of the hose (20, 108) by a means for substantially frictionless removal of the hose (26, 108) from the winding fingers (28), said advance movement being synchronous with a hose removal speed, and wherein the fibrous strip (25, 106) is unwound from a fibrous-strip roll (6, 10, 18) provided with an annular frame (8, 11, 16), which is arranged so that the fibrous-strip roll rotates about said winding mandrel (1). [20.] An apparatus for producing a tubular lining hose (20, 108) comprising:an elongate winding mandrel (1) and at least two reception means (5, 9, 15) which are arranged in spaced relationship with an axis (4) of the winding mandrel (1) such that they are adapted to be rotated about said axis (4) and which are used for receiving thereon fibrous-strip rolls (6, 10, 18); said fibrous-strip rolls (6, 10, 18) being adapted to be rotated about their longitudinal axis and supported in respective reception means (5, 9, 15) in such a way that the fibrous strips are adapted to be would on the winding mandrel (1) and the winding mandrel axis (4), respectively, by a rotary movement of the reception means about the winding mandrel axis and by simultaneous rotation of the fibrous-strip rolls (6, 10, 18) about their own axis;a removing device (21) for removing a wound lining hose (20) from the winding mandrel (1) substantially in the axial direction of said winding mandrel, wherein said winding mandrel (1) has at least two winding fingers (28), which are arranged substantially parallel to each other and a distance of which can be adjusted individually or jointly in a direction radial to the axis (4) of the winding mandrel (1) so as to vary a winding circumference of said winding mandrel (1), said winding fingers (28) being provided with a means for producing an advance movement in a longitudinal direction of the hose so that a substantially frictionless removal of an inner foil hose (26) from the winding fingers (28) takes place, said advance movement being synchronous with a hose removal speed; and,said reception means (5, 9, 15) are each provided with a annular frame (8, 11, 16), which is arranged such that it extends around the winding mandrel (1) and which is supported such that it is adapted to be rotated about said winding mandrel (1).
