Abstract

MéTODO E APARELHO PARA EXTRUDAR UM MATERIAL POLIMéRICO E MéTODO PARA FABRICAR UM PNEU. A presente invenção refere-se a um método de extrusão de um material polimérico. O método compreendendo as etapas de: a) alimentar o material polimérico a um aparelho de extrusão incluindo uma cabeça de extrusão (1), a cabeça de extrusão (1) consistindo de uma matriz macho (12), de uma matriz fêmea (13) coaxialmente disposta com respeito à matriz macho (12); um canal condutor (20), pelo menos uma parte do qual sendo definida entre a matriz macho (12) e a matriz fêmea (13); e b) ajustar uma área em seção transversal da dita pelo menos uma parte do canal condutor (20) pelo reciprocamente deslocar a matriz fêmea (13) com respeito à matriz macho (12) em resposta a uma variação da velocidade de extrusão do material polimérico. A presente invenção trata adicionalmente de um aparelho de extrusão e em um método para fabricar um pneu fazendo uso do aparelho de extrusão.
