Abstract

Un método para formar un sujetador o proyección polimérica unitaria que comprende un soporte flexible resistente y delgado, y una multiplicidad de miembros de gancho delgados espaciados que se proyectan desde la superficie superior del soporte unitario, método que en general incluye la extrusión de una resina termoplástica a través de una placa de matriz, y la placa de matriz está conformada para constituir una capa de base y rebordes, pestanas o elementos de gancho espaciados que se proyectan por encima de una superficie de la capa de base. Cuando la matriz forma los rebordes o pestanas espaciados, la forma transversal de los miembros de gancho son formados por la placa de matriz mientras que el grosor del miembro de gancho inicial se forma mediante el corte transversal de los rebordes en sitios espaciados a lo largo de sus longitudes para formar porciones cortadas discretas de los rebordes. Con posterioridad, el estiramiento longitudinal de la capa de soporte (en la dirección de los rebordes en la dirección de máquina) separa estas porciones cortadas de los rebordes, y la porción cortada forma luego miembros de gancho espaciados. Los miembros de gancho extrusados o de gancho de pestana cortada son luego termotratados lo que provoca la contracción de al menos una porción de al menos el grosor de porción de cabeza del gancho de 5% a 90%, preferentemente de 30% a 90%.
