Abstract

"PROCESSO DE CONSTRUçãO DE UMA ESTRUTURA DE CARCAçA PARA PNEUS, MAIS ESPECIFICAMENTE PARA VEìCULOS DE DUAS RODAS, ESTRUTURA DE CARCAçA E RESPECTIVO PNEU RESULTANTE". Uma junta de carcaça (3) é formada assentado sobre um suporte toroidal (11), uma primeira e uma segunda série de seções em forma de tira (13, 14) cortadas à medida de um elemento em forma de tira contínua (2a) e cada uma compreendendo elementos tipo filamentos longitudinais (15) incorporados em uma camada de material elastomérico (18). As seções (13) da primeira série são sucessivamente assentadas circunferentemente espaçadas por uma distância dada umas das outras, para formar partes laterais (13a) às abas extremas das quais respectivas estruturas de reforço (4) nos talões são aplicadas. As seções da segunda série (14) são individualmente interpostas entre duas seções da primeira série (13), em espaços no seu interior definidos, com as respectivas abas extremas se superpondo às estruturas anulares (4). Cada parte anular (4) compreende um enchimento elastromérico (22) aplicado a uma posição radialmente externa em relação a um único elemento inserto de ancoragem anular (21) formado de pelo menos um elemento alongado enrolado em espiras concêntricas radialmente superpostas (21a).
