Abstract

En un proceso para construir llantas para ruedas de vehículo, una cinta recubierta de hule provista con una pluralidad de cuerdas de refuerzo paralelas embebidas en una matriz de material elastomérico e inclinada por un ángulo predeterminado (a) en relación a una dirección de extensión longitudinal de la cinta recubierta de hule misma, se mueve hacia delante por un transportador a lo largo de una dirección de suministro coincidente con la dirección de extensión longitudinal, hasta exceder una región de corte del transportador por una longitud predeterminada. Un elemento localizador colocado debajo de la cinta recubierta de hule y en la región de corte, es levantado hasta que ocurre el levantamiento de la cinta recubierta de hule. Una cuchilla, colocada sobre la cinta recubierta de hule y en la región de corte, lleva a cabo la incisión de la cinta recubierta de hule y corta ésta entre la cuerdas de refuerzo adyacentes y sobre el ancho completo de la misma para formar un segmento que es subsecuentemente colocado hacia abajo sobre el tambor formador. Antes del corte, una primera parte de la cinta recubierta de hule colocada hacia arriba del elemento localizador es movida hacia delante por un estiramiento predeterminado para reducir la tensión de la cinta recubierta de hule causada por el levantamiento del elemento localizador.
