Abstract

"MéTODO DE CONTROLE PARA A FABRICAçãO DE TUBOS PLáSTICOS ORIENTADOS". Trata-se de um método para expandir um tubo de material plástico, em que um tubo (10), que se desloca longitudinalmente, é expandido progressivamente em seu diâmetro, por pressão interna de fluido, numa zona de expansão (20), entre um bujão (24) a montante e um bujão expansível (26) ajusante. A expansão do tubo (10) é controlada em resposta a parâmetros que indicam direta ou indiretamente a variação na velocidade relativa em que o material é avançado e removido da zona de expansão (20), tal como detecção da velocidade de avanço do tubo a montante (38), diâmetro de expansão primitivo (36), força axial (39) sobre um dispositivo calibrador (28), ou do diâmetro do tubo (41) imediatamente antes da zona de expansão (20).
