Abstract

Procedimiento y aparato para moldear artículos de dos cauchos de colores diferentes, en un molde que tiene una cavidad de molde definida por una pared lateral cerrada, medios que definen una superficie de calidad de molde y un elemento de molde móvil situado dentro de dichos medios de paredes laterales, opuesto a dicha superficie, cuyo elemento de molde móvil tiene un reborde periférico en relación de ajuste deslizante con dicha pared lateral y un rebajo periférico prácticamente continuo adyacente a dicho reborde en su lado encarado en dirección contraria a la citada superficie, caracterizado porque el procedimiento se insufla gas a través de dicha cavidad de molde para eliminar cualquier partícula suelta del primer caucho antes de depositar el segundo caucho en la cavidad del molde.
