Abstract
La invención se refiere generalmente al curado de reencauchados sobre las carcasas de llantas y, más específicamente, al control del encogimiento de los reencauchados durante el proceso de curado de llantas. Específicamente, se refiere a un método de formar una Ilanta reencauchada, que incluye los pasos de aplicar una banda de rodamiento de caucho sustancialmente pre-curada a una porción que acopla la banda de rodamiento de una carcasa de llanta, en donde la banda de rodamiento tiene un ancho inicial y una capa de goma cojín interpuesta entre la banda de rodamiento y la carcasa de llanta, cubrir por lo menos la banda de rodamiento con una membrana flexible de curado para formar un ensamble de curado de llanta que tiene un compartimiento de presurización interpuesto por lo menos entre la membrana y la banda de rodamiento, y poner el ensamble de curado de llanta en una cámara de un molde de curado, mejoramiento que incluye los pasos de: (i) presurizar la cámara a una presión predeterminada de la cámara; (ii) calentar la cámara a una temperatura predeterminada; (iii) presurizar el compartimiento a una presión predeterminada del compartimiento mayor que 101.35 kPa y menor que la presión de la cámara para proporcionar un diferencial de presión entre la cámara y el compartimiento, iniciándose el paso después de que se inicia el paso de presurizar la cámara y por lo cual se provee un ancho final de la banda de rodamiento que es igual o mayor que 98.0% del ancho inicial de la banda de rodamiento cuando el ancho inicial de la banda de rodamiento es aproximadamente 290-500 mm.
