Abstract

La invención incluye métodos y aparatos para desmoldar una rodadura. Los métodos incluyen disponer uno o más rodillos para extenderse a través de una extensión transversal de una cavidad de desmoldeo de rodadura y a través de un lado exterior expuesto de una rodadura. El uno o más rodillos pueden girar libremente y se disponen para definir una vía de desmoldeo de la rodadura que se extiende desde el molde. La rodadura se desmolda de la cavidad de moldeo de rodadura a lo largo de la vía de desmoldeo de modo que la rodadura se dirige inicialmente hacia afuera desde una posición moldeada dentro de la cavidad de moldeo de rodadura a un ángulo inicial menor que 90 grados desde la posición moldeada, la rodadura continúa a lo largo de la vía de desmoldeo hasta que la rodadura se dirige lejos de la cavidad de moldeo en una dirección de 90 grados desde la posición moldeada a una posición perpendicular ubicada a una distancia de la cavidad de moldeo al menos igual a aproximadamente 80% del espesor de rodadura.
