Abstract
"MéTODO DE REMOVER UM SUPORTE TOROIDAL DESMONTáVEL DE UM PNEU VULCANIZADO". Um suporte toroidal (1) compreende setores circunferencialmente distribuídos cada um tendo um corpo principal substancialmente em forma de U e uma placa de afixação (22) a ser engatada entre um flange (24) e um contra-flange (25). A conformação de setores (2a, 2b) habilita a criação, durante a vulcanização, de um fluxo de vapor varrendo a inteira superfície interna do suporte toroidal a uma curta distância da superfície interna do pneu (5), para que uma transmissão de calor eficiente e homogênea seja assegurada. Para remoção do suporte toroidal (1), cada setor, após o desengate do flange (24) e contra-flange (25), é extraído do pneu (5) por um movimento radial centrípeta combinado com oscilação angular em torno de eixos geométricos opostos (K, K') colocados cada um próximo a uma região de ressalto do pneu (5). Fluido de trabalho sob pressão pode ser admitido entre o pneu (5) e o suporte toroidal (1) para causar uma separação preliminar do pneu propriamente dito.
