Abstract

MéTODO E APARELHO PARA FABRICAR PNEUS PARA RODAS DE VEìCULO Em um método de fabricar pneus para rodas de veículo, um pneu verde (2), uma vez formado, é transferido em um molde de vulcanização (1) e pressionado contra as paredes de contenção (6) de uma cavidade de moldagem (3). Simultaneamente com a etapa de pressão, um fluido presente entre o pneu verde (2) e as paredes de contenção (6) é evacuado por válvulas de suspiro (l1). O pneu (2) é trazido em contato com a cabeça de fechamento (18) de cada válvula (l1) para empurrá-lo para uma posição fechada da própria válvula (11). A cabeça de fechamento (18) tem uma porção distal (34) enfrentando a cavidade de moldagem (3) e incluindo pelo menos um elemento de aperto (34a) para a mistura de pneu, de forma que o membro de fechamento (17) seja puxado para a posição aberta enquanto o pneu moldado e curado (2) é movido longe da superfície interna (7) de dita cavidade de moldagem (3).
