Abstract

Dispositif destiné à être intercalé entre une couche inférieure et une couche supérieure de particules disposées dans une enveloppe cylindrique, de manière à limiter ou supprimer la migration des particules entre les couches, ledit dispositif comprenant une couronne de toile présentant : - des mailles de diamètre équivalent inférieur au diamètre équivalent des particules, - une longueur égale au périmètre interne de la base de l'enveloppe cylindrique, - une partie supérieure présentant une extrémité supérieure destinée à être fixée sur toute sa longueur à la paroi interne de l'enveloppe cylindrique, et - un partie inférieure comprenant au moins six plis couchés identiques, chaque pli étant formés par deux arêtes se rejoignant en un point et les plis étant espacés les uns par rapport aux autres de manière à ce que la partie inférieure soit sensiblement perpendiculaire à la partie supérieure lorsque les plis couchés sont en position pliée.
