Abstract
Perfeccionamientos introducidos en aparatos para curvar y templar láminas de vidrio, caracterizados porque comprendiendo un horno de calentamiento, una sección de enfriamiento, y una sección de refrigeración, dispuestas, esencialmente, en línea o cadena la una con la otra, un transportador para sujetar y transportar una lámina de cristal a lo largo de un camino, en general, horizontal por dicho horno, sección de enfriamiento y sección de refrigeración, medios en el horno para calentar la lámina a medida que pasa por el mencionado horno con el fin de, una manera esencial, alcance el cristal la temperatura de reblandecimiento, y medios en la sección de enfriamiento para dirigir un medio gaseosos de enfriamiento a presión contra las superficies opuestas de la lámina a medida que ésta pasa avanzando por la mencionada sección de enfriamiento, medios para aplicar el medio de enfriamiento a la superficie inferior de la lámina a una presión mayor que la presión del medio de enfriamiento aplicada ala superficie superior de la misma, enfriando así la superficie inferior a mayor velocidad que la superficie superior, lleva una serie de rodillos montados dentro de la sección de enfriamiento por encima de la sección de transporte para limitar el movimiento ascendente de la lámina y hacer avanzar la misma por un segundo camino o recorrido paralelo a, pero separado por encima de, el primer camino, comprendiendo cada uno de los rodillos una parte central que, en general, se prolonga en sentido horizontal, dentro de un paralelismo esencial con el transportador, partes extremas opuestas con un eje común dispuesto por encima de la parte central y partes inclinadas que conectan las partes extremas a la mencionada parte central.
