Zusammenfassung:	A method of applying an additive (4) to selected regions (56) of a web (4) includes the steps of applying the additive to the raised regions (26) of a patterned roll (10) having an outer surface comprising raised regions and recessed regions (39), providing a flat roll (12) having a smooth outer surface arranged in rotatable contact with the patterned roll, and conveying the web of material between the patterned roll and the flat roll, thereby to transfer the additive to selected regions of the web. An apparatus for selectively applying an additive to a web is also described. Se describe un metodo para aplicar un aditivo (4) a regiones seleccionadas (56) de una tela (4) que incluye las etapas de aplicar el aditivo a las regiones elevadas (26) de un rodillo modelado (10) que tiene una superficie externa que comprende regiones elevadas y regiones huecas (39), proporcionar un rodillo plano (12) que tiene una superficie externa lisa arreglada en contacto giratorio con el rodillo modelado, y transportar la tela de material entre el rodillo modelado y el rodillo plano, de tal modo que se transfiere el aditivo a las regiones seleccionadas de la tela. Tambien se describe un aparato para aplicar selectivamente un aditivo a una tela.
