Abstract

Perfectionnements aux bandes allongées dont la structure détermine un échange de fluide entre leur zone centrale et un milieu dans lequel elles sont introduites, du type comportant un ensemble de canaux longitudinaux dont les parois externes permettent cet échange, perfectionnements résidant dans le fait que la bande est constituée par une structure creuse aplatie obtenue par extrusion d'une polyoléfine comportant entre ses faces extérieures aplaties des cloisons longitudinales définissant lesdits canaux, lesdites faces extérieures étant ajourées en fonction du terrain et du débit, à un degré correspondant à la différence de pression du fluide à échanger entre lesdits canaux et le milieu extérieur.
