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