Abstract

Máquina para la construcción de neumáticos, que comprende un tambor de construcción de neumáticos montado para rotación en torno de un eje generalmente horizontal, una serie de dedos volvedores circunferencialmente espaciados, y un miembro de accionamiento que puede aplicarse operativamente con las partes extremas interiores radialmente de dichos dedos y montado para movimiento axial, teniendo cada dedo una superficie de leva curva radialmente interior, un primer medio de leva para aplicarse a la superficie de leva de cada dedo para hacer oscilar la parte radialmente exterior del dedo sobre los salientes del tambor hasta una posición avanzada predeterminada contra el tambor en respuesta al movimiento axial de dicho miembro de accionamiento apartándose de dicho tambor, medios para hacer oscilar la parte radialmente exterior de cada dedo desde dicha posición avanzada hasta una posición retraida predeterminada y medios para oprimir la parte extrema radialmente interior de cada dedo contra dichos medios de leva cuando el dedo está adyacente a dicha posición avanzada y para resistir el movimiento de dicha parte extrema interior más allá de dichos medios de leva como movimiento de retracción del dedo iniciado para hacer que el dedo pivote en general donde el dedo toca dichos primeros medios de leva.
