Abstract

Dispositivo para la fabricación de cámaras de aire para cuerpos huecos hinchables, caracterizado por el hecho de comprender dos semimatrices y un noyo acoplables y alejables entre si, royo que tiene parte de su superficie externa, de forma complementaria de las superficies enfrentadas a él de las dos semimatrices, a fin de formar con estas últimas un par de cámaras substancialmente anulares y mutuamente complementarias para originar una forma tórica hueca, en el que una de las semimatrices y la superficie del noyo enfrentada a ella presentan superficies cilíndricas coaxiales, estando previstos en el noyo conductos para el envio de material elastómero a las cavidades definidas entre las semimatrices y el noyo, medios para alejar las semimatrices del noyo, medios para retirar el noyo del espacio comprendido entre las dos semimatrices y medios para acercar entre sí las dos semimatrices poniendo en con tacto recíproco y directo los bordes de las mismas, medios para enviar un fluido a presión ala cavidad cerrada definida entre las dos semimatrices y medios para vulcanizar el material elastómero.
