Abstract

La superficie de formacion (5) para la postformacion de un cordon perfilado (2) en forma de marco extruido sobre un encristalado (1), está ligeramente curvada en el sentido de la longitud del cordon perfilado (2). En la posicion final del punzon de formacion (5) al momento de la operacion de postformacion, las aristas de delimitacion laterales (22, 25) se encuentran por consecuencia ligeramente por arriba de la superficie del cordon perfilado (2). De tal suerte se evitan marcas en forma de líneas o de aristas sobre el cordon perfilado, o se realiza una transicion continua entre la longitud postformada del cordon perfilado y el cordon perfilado que le está empalmado.
