Abstract:
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.
