Disclosed is a method for producing a web (2) comprising at least one protective layer (11, 11a), at least one functional layer (13), and at least one reinforcement layer (14). The reinforcement layer (14) is provided with greater tear strength than the protective layer (11, 11a) while the reinforcement layer (14) is glued to the functional layer (13) or the protective layer (11, 11a). According to the inventive method, the functional layer (13) is welded together with at least one protective layer (11, 11a) on at least one side by means of heat lamination in order to produce a prelaminate (20), and the obtained prelaminate (20) is then glued to the reinforcement layer (14).

1. A method for the production of a web having at least one protective layer, at least one functional layer and at least one reinforcement layer having open areas, the method comprising of: providing, from a supply roller, a film and least one protective layer which is a web;forming the at least one functional layer as a continuous sheet by welding by heated rollers the at least one protective layer to the film through thermal lamination, the at least one functional layer being a prelaminate;conveying the prelaminate to a reinforcement layer application step;providing a reinforcement layer as a continuous sheet from a roller, wherein the reinforcement layer has a greater tear strength than the at least one protective layer;applying to the reinforcement layer and the prelaminate an adhesive subsequent to the forming of the prelaminate;subsequent to applying to the reinforcement layer the adhesive, conveying the reinforcement layer;providing, from a roller, an outer protective layer as a continuous sheet; andadhering, by pressure rollers, the reinforcement layer to the prelaminate and the outer protective layer to the reinforcement layer. 2. Method as set forth in claim 1, wherein the functional layer is welded on one side to the protective layer and that the thus-obtained prelaminate is subsequently adhered on the side of the functional layer to the reinforcement layer. 3. Method as set forth in claim 1, wherein the thermal lamination is performed inline. 4. Method as set forth in claim 1, wherein the reinforcement layer is adhered to the functional layer, wherein an adhesive is applied in such a manner to the functional layer and/or to the reinforcement layer that, during the subsequent bonding of the reinforcement layer to the functional layer, common contact surfaces of the bonded layer are adhered to each other substantially over their entire surfaces. 5. Method as set forth in claim 4, wherein the adhesive is sprayed on or sprinkled on in such a manner and swirled in such a manner that a substantially full-surface application of the adhesive on the contact surfaces of the functional layer and/or the reinforcement layer results. 6. Method as set forth in claim 4, wherein the adhesive is sprayed on or sprinkled on and the functional layer and/or the reinforcement layer are electrostatically charged such that a substantially full-surface application of the adhesive on the contact surfaces results. 7. Method as set forth in claim 4, wherein the adhesive is applied through openings in the reinforcement layer onto the functional layer and/or on the reinforcement layer. 8. Method as set forth in claim 4, wherein contact surfaces of the reinforcement layer and the further layer are adhered to each other substantially over their entire surfaces. 9. Method as set forth in claim 4, wherein in a single operation the adhesive is applied to both layer sides of the reinforcement layer. 10. Method as set forth in claim 4, wherein the reinforcement layer is adhered in one operation to the functional layer and a further layer. 11. Method as set forth in claim 4, wherein the adhesive is applied such that a non-vapor-retardant web is produced.
