Abstract

MéTODO E APARELHO PARA FABRICAR PNEUS. Um braço robotizado (38a, 38b) aciona em rotação um tambor (15) portador de um pneu (2) sendo processado e conveniente o coloca em frete de uma tubeira distribuidora (23) fornecendo um elemento alongado contínuo de material elastomérico de maneira a formar um componente de pneu (5a, 5b) A tubeira distribuidora (23) é conectada através de pelo menos urna válvula seletora (25) com duas ou mais extrusoras (19, 20, 47) cada configuração para fornecer uma respectiva mistura. A válvula seletora (25) conecta a tubeira distribuidora (23) com a saída de uma das extrusoras, interrompendo a comunicação entre a tubeira e as outras extrusoras. As sidas das extrusoras não ativas podem ser conectadas com pelo menos um duto de saída. é assim possível substituir o tipo de mistura usado para fabricar o componente de pneu sem o artigo de manufatura ter de ser afastado da tubeira distribuidora (23).
