Abstract
La présente invention concerne une installation de formation à sec qui comprend au moins une unité de distribution qui a une entrée de fibre et d'air. Une telle unité de distribution est placée au-dessus d'un fil de formation à l'opposé d'au moins une boîte à vide qui est reliée à une unité d'aspiration. L'unité de distribution a un fond ouvert pour la libération du matériau fibreux sur le fil de formation sous l'unité de distribution. Davantage de rouleaux rotatifs ayant des pointes en saillie sont prévus dans l'unité de distribution pour couvrir la section transversale du fond ouvert. La boîte à vide est divisée en au moins trois zones longitudinales dans une direction transversale à la direction d'avance du fil de formation. Lesdites zones longitudinales comportent des entrées orientées vers le haut agencées sous le fil de formation. Les zones longitudinales sont reliées à l'unité d'aspiration par l'intermédiaire d'une sortie. La sortie comprend des premiers moyens d'obturation pour fermer partiellement ou totalement la sortie. Les premiers moyens d'obturation sont indépendamment actionnables.
