Abstract

"CABEçA DE SOPRO DE FOLHA PARA FABRICAçãO DE FOLHAS TUBULARES". A invenção refere-se a uma cabeça de sopro de folha para fabricação de folhas tubulares de plástico termoplástico com ao menos um canal de adução para a massa fundida de plástico, que desemboca em um bocal de saída anelar, com condutos para adução e descarga de ar de refrigeração interno e com um anel de refrigeração externo abrangendo o tubo de plástico extrudado, o qual está subdividido em setores, em que o ar soprado sobre o tubo de folha extrudado é distintamente aquecível e/ou resfriável. De acordo com a invenção, na cabeça de sopro de folha estão integrados, adicionalmente, cartuchos de aquecimento distribuídos pela periferia e/ou na cabeça de sopro de folha podem estar dispostas perfurações adicionais na periferia, as quais estão alinhadas essencialmente verticalmente ao anel de refrigeração externo, sendo que das mesmas é soprável ar distintamente temperável, e sendo que estão previstas respectivamente uma primeira unidade de controle para os cartuchos de aquecimento e/ou elementos de refrigeração no anel de refrigeração externo e uma segunda unidade de controle para os cartuchos de aquecimento na cabeça de sopro de folha.
