Abstract

LAS CUERDAS (24), EN LAS CUALES SE HAN LIMITADO PARTES METALICAS (22) A REVESTIR MEDIANTE PUNTOS DE SEPARACION (26) PREFORMADOS, SON LLEVADAS AISLADAS DELANTE DE UN ESPACIO HUECO DE MOLDEO (20). DESPUES SON EMPUJADAS HASTA UN TOPE (60) EN EL ESPACIO (20) Y SON SOMETIDAS A UNA FUERZA DE EMPUJE POR LA CUAL SE CURVAN EN FORMA DE LINEA SINUOSA PARA CONSTITUIR UNA RESERVA LONGITUDINAL EN EL TRAMO DELANTE DEL ESPACIO (20). A CONTINUACION SE FIJA LA PRIMERA PIEZA METALICA (22) DE CADA CUERDA (24) EN EL MOLDE DE REVESTIR (18). LA FUERZA DE EMPUJE NO SE ANULA HASTA QUE LA PRIMERA PIEZA METALICA (22) QUEDA FIJADA; CON ELLO, LAS CUERDAS (24) SE LIBERAN PARA RETROCEDER A LO LARGO DE SU RESERVA LONGITUDINAL. A CONTINUACION, LAS CUERDAS (24) SE TENSAN DE NUEVO Y SE ROMPEN EN SU PRIMER PUNTO DE SEPARACION (26). CON ELLO SE EVITA QUE LAS TOLERANCIAS DE DISTANCIA ENTRE LOS PUNTOS DE SEPARACION (26) SE ACUMULEN A POSIBLES FALLOS, LO CUAL IMPEDIRIA LA ROTURA DE LAS CUERDAS (24) EN LOS PUNTOS DE SEPARACION (26) PREFORMADOS.
