Abstract

Perfeccionamientos en los aparatos de moldeo por inyección, del tipo en el que se fabrican las cadenas de cierre de cremallera continuas repitiendo las etapas de desplazar un molde móvil respecto de un molde fijo para abrir y cerrar los moldes de modo intermitente, moldear por inyección una fila de elementos de acoplamiento en partes de un par de cintas de soporte introducidas a través de dichos moldes y posicionadas entre ellos cuando se cierran los moldes, y luego interrumpir el posicionamiento de dichas cintas soportes y subsiguientemente alimentarlas cuando se abren dichos moldes en preparación a una operación siguiente de moldeo por inyección, caracterizados porque el aparato comprende: unos medios para formar un saliente en una parte de un larguero moldeado conjuntamente con dicha fila de elementos de acoplamiento en el momento del moldeo por inyección, unos medios para detener la introducción de dichas cintas en el espacio entre dichos moldes en respuesta a la detección de dicho saliente y unos medios para retraer y tensar dichas cintas ya introducidas en el espacio entre dichos moldes para posicionar dentro de dichos moldes la parte de dichas cintas sobre la que se han de moldear subsiguiente por inyección las filas de elementos de acoplamiento, sirviendo el extremo posterior de dicho larguero previamente moldeado en dichas cintas conjuntamente con las filas de elementos de acoplamiento como patrón de posicionado de dichas cintas.
