Abstract

''PNEUMáTICO, PROCESSOS PARA A FABRICAçãO DE UMA CAMADA DE BORRACHA NãO VULCANIZADA E DE UMA CAMADA DE BANDA DE RODAGEM, E, APARELHAGEM PARA A EXECUçãO DO PROCESSO DE OBTENçãO DE UMA CAMADA PROVIDA DE UM INSERTO". Pneumático que compreende uma banda de rodagem (3) composta por duas camadas (31,32) circunferenciais, cuja carga de reforço é majoritariamente uma carga não condutora, cada camada (31,32) contendo um inserto circunferencial (11,12) de mistura condutora, que tem na parede de contato (310) entre as duas camadas (31, 32) uma superfície circunferencial, a primeira dessas camadas (31, 32) tendo na dita parede uma superfície circunferencial de traçado circular de largura e, a segunda camada (31, 32) tendo na dita parede uma superfície circunferencial com um traçado de largura e' que vai cruzando o mesmo e que apresenta cristas de um lado e de outro do traçado circular da primeira camada, de modo que haja circunferencialmente entre os dois traçados vários pontos de contato que asseguram a conexão elétrica entre os dois elementos condutores. A dita segunda camada com inserto é extrudada por meio de um aparelho que compreende uma extrusora principal (10) para extrudar a parte (31, 32) de uma banda de rodagem (3) não vulcanizada e uma micro extrusora (40), da qual o bico de extrusão
