Abstract

"ROLOS DE GUIA PARA CALIBRADORES DE EXTRUSãO DE FILMES PLáSTICOS TUBULARES". Rolo de guia (9) para calibradores de extrusão (1) de filmes plásticos tubulares (7) providos com uma superfície removível e intercambiável (10) feito de um material tendo uma elevada isolação térmica e um bom coeficiente de atrito. Tais características permitem um fluxo regular do filme que está sendo extrudado (7) e dispersão térmica de resfriamento uniforme ao longo do desenvolvimento da superfície do citado filme.
