Abstract

Patente de Invenção: <B>"CABEçA DE EXTRUSãO"<D>. A invenção refere-se a uma cabeça de extrusão para produzir uma preforma (22)tubular, a fim de produzir corpos ocos de matéria plástica de grande volume, moldados por sopro. A cabeça de extrusão de acordo com a invenção tem um bocal de saída de tubo anular, ajustável, para ajustar seletivamente a fenda de bocal (20), a fim de alterar a espessura de parede da preforma (22)sendo ejetada. A fim de obter uma ajustabilidade múltipla da seção transversal do tubo extrudado, a invenção prevê que a cabeça de extrusão compreenda pelo menos três elementos de ajuste de bocal/fenda de mandril (D O = mandril, DS I, DS II, DS III) separados, que estão perfilados de modo diferente e são trocáveis. Os referidos elementos podem ser levados ao contato de trabalho,individualmente e/ou simultaneamente, com a preforma
