Abstract

PROCESSO PARA FABRICAR PNEUMÁTICOS, E, APARELHO PARA FABRICAR PNEUS. Em um processo para fabricar pneumáticos, uma luva de carcaça (14) é produzida que compreende pelo menos uma lona de carcaça (3) provida com abas axialmente opostas (3a) viradas para cima em tomo de estruturas de ancoragem anulares (5), a fim de formar respectivos anéis (16). Uma luva externa (35) é posicionada em tomo da luva de carcaça (14) e a última é radialmente expandida a fim de causar a aplicação da mesma contra uma superficie radialmente interna da luva externa (35). Após cada uma das abas (3a) ter sido virada para cima e antes da expansão radial, somente uma parte (25) pertencente a cada um dos anéis (16) e estendendo-se substancialmente paralela à respectiva estrutura de ancoragem anular (5) é submetida a uma etapa de aquecimento sob pressão, para produzir cada anel (16) integral com a estrutura de ancoragem anular (5) e evitar que a lona/lonas viradas para cima deslizem parcialmente para fora, durante a subsequente etapa de expansão radial da luva de carcaça (14) e etapa de vulcanização do pneu (2).
