Abstract

Un método para formar deformaciones en una trama de tela no tejida incluye las etapas de: a) proporcionar una trama de tela no tejida precursora; b) proporcionar un par de miembros conformadores que incluyen un primer miembro conformador que tiene una superficie que comprende una pluralidad de elementos conformadores macho distintos y separados; y un segundo miembro conformador que tiene una superficie que comprende una pluralidad de hendiduras en el segundo miembro conformador, en donde las hendiduras se alinean y configuran para recibir los elementos conformadores macho en ellas, en donde las hendiduras tienen una periferia de vista en planta que es mayor y que puede rodear completamente la periferia de la vista en planta de los elementos macho; y c) deformar mecánicamente la trama de tela no tejida precursora con los miembros conformadores por la colocación de la trama de tela no tejida precursora entre los miembros conformadores. Al menos uno del primer miembro conformador o el segundo miembro conformador tiene una pluralidad de elementos de textura de superficie distintos en él. El método forma una trama de tela no tejida que tiene una primera región generalmente plana y una pluralidad de deformaciones distintas. Las deformaciones forman salientes que se extienden hacia afuera desde la primera superficie de la trama de tela no tejida y una abertura de la base adyacente a la segunda superficie de la trama de tela no tejida.
