Abstract

"CANAL DE FLUXO DUPLO PARA UMA CABEçA EXTRUSORA". A invenção provê um método e aparelho para formação simultânea de duas ou mais tiras elastoméricas de perfis transversais predeterminados a partir de um material. O material é recebido de uma extrusora em um canal de entrada onde ele é dividido em uma primeira e uma segunda passagem de fluxo angular. O material passa através de uma área de transição onde ele é endireitado e o centro de massa do material é movido para alinhamento com o centro de um desviador localizado em um canal de descarga a jusante. O material é então descarregado em um pré-formador e matriz.
