Abstract

La presente invencion proporciona un método para perforar selectivamente una trama no tejida (102). Una trama no tejida (102) es atenuada a lo largo de una pluralidad de ubicaciones y luego se aplica una fuerza tensionante a la trama no tejida (102) haciendo que la trama no tejida (102) rompa en la pluralidad de ubicaciones atenuadas, cenado una pluralidad de aberturas en la trama no tejida (102) que coinciden con las ubicaciones atenuadas.
