Abstract

UN METODO PARA PRODUCIR PASADORES CON HEBRAS QUE PRODUCEN HEBRAS LIBRES DE COSTURAS. EL METODO EMPLEA UN TROQUEL LAMINADOR CON UNA NUEVA GEOMETRIA DE PERFIL DE HEBRA DE FORMA DOBLE DONDE EL ANGULO DEL DIVERGENCIA DE LAS PAREDES QUE DEFINEN LA HENDIDURA DEL TROQUEL VARIA GRADUALMENTE ENTRE UN ANGULO DE AGUZAMIENTO OBTUSO Y UN ANGULO DE TERMINACION AGUDO A MEDIDA QUE LA PROFUNDIDAD DE LA HENDIDURA AUMENTA DESDE UNA PROFUNDIDAD INICIAL A UNA PROFUNDIDAD TERMINAL. LA FORMA ACABADA DEL TROQUEL SE MANTIENE DURANTE UNA CIERTA LONGITUD QUE ES CONMENSURABLE CON AL MENOS DOS REVOLUCIONES Y MEDIA DEL PASADOR QUE SE PRODUCE.
