Abstract

"MéTODO E APARELHO PARA RESFRIAMENTO DE MANGUEIRAS DE FOLHA PLáSTICA EXTRUSADAS". Essa invenção refere-se a um método para resfriamento de mangueira de folha (F) plástica extrusada, que é resfriada pela condução de um refrigerante pressurizado ao longo da margem interna e/ou externa da mangueira de folha (F). O refrigerante é alimentado na área de uma abertura de extração (4) no sentido tangencial à mangueira de folha (F), e o refrigerante assim gerado é conduzido como uma corrente espiral (16,17) da entrada tangencial, (6) para a saída por uma força centrífuga que afeta o refrigerante ao longo da superfície interna e/ou externa da mangueira de folha (F), e pelas diferenças de densidade e pressão entre várias partes do refrigerante. O dito aparelho (1) compreende uma unidade de resfriamento interna (1~ B~) equipada com um tambor de distribuição (2) provido com bicos (13) com entradas tangenciais (13~ A~). Sua unidade de resfriamento externa (1A) tem uma entrada tangencial (6), que está em conexão com um canal anular (G) ao redor da mangueira de folha (F), delimitado por um elemento tubular (5,P).
