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%.A method for forming a unitary polymeric fastener or projection comprising a resilient and thin flexible support, and a multiplicity of spaced thin hook members projecting from the upper surface of the unit support, a method that generally includes the extrusion of a thermoplastic resin through a matrix plate, and the matrix plate is shaped to constitute a base layer and spaced flanges, flanges or hook elements projecting above a surface of the base layer. When the die forms the spaced flanges or flanges, the transverse shape of the hook members is formed by the die plate while the thickness of the initial hook member is formed by cross-cutting the flanges at spaced sites along their lengths to form discrete cut portions of the flanges. Subsequently, the longitudinal stretching of the support layer (in the direction of the flanges in the machine direction) separates these cut portions from the flanges, and the cut portion then forms spaced hook members. The extruded hook members or cut flange hook are then heat treated which causes at least a portion of at least a portion of the head portion of the hook to be contracted from 5% to 90%, preferably 30% to 90%.
