Abstract
"PNEU COM ESTRUTURA DE LONA COMPOSTA E PROCESSO DE MANUFATURA". O processo de construção de um pneu 10 tendo uma montagem de carcaça 18, tendo um par de núcleos do talão 26 e uma estrutura de reforço de lonas radiais 17, que compreende as etapas de aplicação cilíndrica de um par de lonas de costado reforçadas com cordões radiais 17a, 17b, cada lona do costado tendo uma largura Wp; encaixe de um núcleo do talão 26 em cada lona do costado 17a, 17b e fixação do espaçamento axial entre os núcleos do talão 26 a uma distância L; aplicação de uma lona de coroa 50 tendo uma largura Wc, Wc sendo menor do que a distância L e a lona da coroa 50 sendo interposta entre e espaçada de cada lona do costado 17a, 17b; redobra de cada lona do costado 17a e 17b para sobrepor as bordas laterais da lona da coroa 50; e movimentação da montagem da carcaça 18 axialmente para dentro, enquanto moldando a montagem da carcaça 18 toroidalmente, para formar redobras da lona 20a, 20b axialmente para dentro dos núcleos do talão 26. O processo compreende ainda as etapas de aplicação de uma ou mais camadas de reforço da correia na carcaça e na primeira camada de reforço e aplicação de uma banda de rodagem para formar um pneumático de banda de rodagem de lonas radiais.
