Abstract

CABEçA DE MATRIZ DE FILME PARA PRODUçãO DE FILME TUBULAR SOPRADO. A presente invenção refere-se a uma cabeça de matriz de filme para a produção de filme tubular soprado a partir de polímeros termoplásticos. Os filmes produzidos com cabeças de matriz convencionais geralmente apresentam estrias rombudas ou áreas onduladas, as linhas sulcadas assim denominadas. O objetivo da invenção é o de impedir estas propriedades negativas do filme por meio de uma cabeça de matriz de filme com vários canais de material fundido (9, 10, 11) na forma de fendas anulares dispostas concentricamente em torno do eixo central da cabeça de matriz de filme, onde o distribuidor espiral (8) do canal de material fundido interno fica localizado em relação ao eixo central da cabeça de matriz na parede delimitadora interna e o distribuidor espiral (6) do canal de material fundido externo fica localizado em relação ao eixo central da matriz de cabeça na parede delimitadora externa.
