Abstract

"TAMBOR DE CONSTRUçãO DE PNEU TENDO SEçãO CENTRAL EXPANSìVEL E CONJUNTOS DE TRAVA DE TALãO INDEPENDENTEMENTE EXPANSìVEIS NAS SEçõES DE EXTREMIDADE". Trata-se de um tambor de construção de pneu que tem uma seção central (720) e duas seções de extremidade (722, 724). Cada seção de extremidade é dotada de um conjunto de trava de talão expansível (726). A seção central, de preferência, é expansível. o conjunto de trava de talão expansível compreende um anel carregador (CR) e uma pluralidade de liames alongados (K) que se estendem entre o anel carregador (CR) e uma pluralidade de segmentos radialmente expansíveis (S). quando o anel carregador se move para dentro (na direção da seção central), os segmentos radialmente expansíveis (S) se movem radialmente para fora, impelindo uma pluralidade de segmentos de dedo circunferencialmente espaçados, que se estendem axialmente (F) para fora a partir de uma posição encolhida até uma posição expandida, e pelo menos uma posição entre elas. Em uma modalidade da invenção, o conjunto de trava de talão compreende um cilindro e dois pistões (P1, P2) dispostos dentro do cilindro. Os pistões são livres para se mover axialmente dentro do cilindro, em resposta à pressão pneumática. o primeiro pistão (P1) é restringido quanto a se mover axialmente para dentro por hastes (R1P1, R2P1, R3P1) . O segundo pistão (P2) é conectado por hastes (R1P2, R2P2, R3P2) ao anel carregador. Ar pressurizado fornecido através de mangueiras (H1, H2, H3) e passagens no cilindro (73) controlam o movimento dos pistões (P1, P2) tal que o conjunto de trava de talão pode ser parcialmente expandido, totalmente expandido, e posição retraída, não expandida.
