Abstract

"SUPORTE TOROIDAL DESMONTáVEL PARA A FABRICAçãO DE PNEU". Um suporte toroidal (1) compreende setores circunferencialmente distribuídos, cada um possuindo um corpo principal substancialmente em forma de U e uma placa de anexação (22) para ser encaixada entre um flange (24) e um contra-flange (25). A conformação dos setores (2a, 2b) possibilita a criação, durante a vulcanização, de um fluxo de vapor lambendo toda a superfície interna do suporte toroidal a uma curta distância da superfície interna do pneu (5), de modo que uma transmissão de calor eficaz e homogênea seja assegurada. Para a remoção do suporte toroidal (1), cada setor, após desencaixe da flange (24) e do contra-flange (25), é extraido do pneu (5) por uma movimentação radial centrípeta combinada com oscilações angulares ao redor de eixos opostos (K, K') colocados, cada um, próximos a uma região de ombro do pneu (5). O fluido funcional sob pressao pode ser admitido entre o pneu (5) e o suporte toroidal (1) para causar uma separação preliminar do próprio pneu.
