摘要：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).

主权项：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; and adhering, by pressure rollers, the reinforcement layer to the prelaminate and the outer protective layer to the reinforcement layer.
