Abstract
Un molde expansible en secciones para la vulcanización de correas, que comprende un núcleo cilíndrico constituído por un número par de secciones en forma de teja de dos en dos contrapuestas y simétricamente contraibles y expansibles respecto a un plano que pasa por el eje central del molde con medios para provocar la expansión y la contracción de dichas seccionen, caracterizado por el hecho que los medios para provocar la expansión de las secciones consisten en un conjunto de cuñas, vinculadas a un deslizable aptas de interactuar con unos planos inclinados llevados por pares de secciones contrapuestas, por el hecho de proveer medios para centrar las secciones en su acoplamiento y medios para bloquear las secciones en posición de expansión.
