Abstract

"PROCESSO PARA FABRICAçãO DE UM PNEUMáTICO". Pelo menos uma lona de carcaça (3) é formada pela deposição de um elemento em forma de tira (13) compreendendo elementos em forma de fio torcido (13 a) longitudinais, incorporados em uma camada de material elastómero (13b), sobre um suporte toroidal (11). A deposição do elemento em forma de tira (13) ocorre segundo seções de deposição alternadas (23, 24), cada uma compreendendo duas porções laterais se estendendo radialmente (23a, 23c, 24a, 24c) e uma porção de coroa (23b, 24b) se estendendo em uma posição radialmente externa. As porções laterais de cada seção de deposição (23, 24) são, pelo menos parcialmente, sobrepostas às porções laterais pertencendo a uma seção de deposição adjacente. Associado com a lona de carcaça (3) há estruturas anulares (4) compreendendo um inserto anular circunferencialmente inextensível (32) axialmente externo a um elemento de ancoragem (31). Uma estrutura de cinta (5), uma banda de rodagem (8) e paredes laterais (9) são combinados com a assim formada estrutura de carcaça (2) para definirem um pneumático (1) a ser submetido a uma etapa de vulcanização.
