Title (EN) DEVICE FOR DRY FORMING A WEB OF FIBERS
(FR) DISPOSITIF DE FORMATION A SEC D'UNE BANDE DE FIBRES
Abstract: front page image
(EN)What is described is a device for dry forming a web of fibers, comprising: a fiber distribution head (1); a forming wire (3) movable under said head; a suction means (5) located on the opposite side of said forming wire from said head; within said head, a chamber (9) into which a flow of gas, in which said fibers are suspended, is directed, the chamber having a buttom opening (9A) closed by a screen mesh (17) which is essentially parallel to said forming wire (3) and which faces the latter; and agitator members (45) inside said chamber, above said screen mesh (17), for agitaing and distributing the fibers. Characteristically, the screen mesh (17) is a continuous mesh, movable along a closed path around said chamber, the portion of said mesh parallel to and facing the forming wire moving along a path which is essentially parallel to said forming wire. Additionally, the agitator members comprise a plurality of rotating shafts (47) which are parallel to each other and othogonal to the direction of advance (f3) of said forming wire.
(FR)L'invention concerne un dispositif de formation à sec d'une bande de fibres comprenant : une tête de distribution de fibres (1) ; un câble de formation (3) qui peut bouger sous ladite tête ; un moyen d'aspiration (5) situé sur le côté opposé dudit câble de formation de la tête ; la tête comprenant une chambre (9) dans laquelle un flux de gaz, dans lequel les fibres sont suspendues, est orienté, cette chambre possédant une ouverture inférieure (9A) fermée par un tamis (17) qui est essentiellement parallèle audit câble de formation (3) et qui fait face à ce dernier ; et des éléments d'agitateur (45) situés à l'intérieur de la chambre, au-dessus du tamis (17), afin de secouer et de répartir les fibres. En général, le tamis (17) consiste en un tamis continu qui peut se déplacer le long d'un trajet fermé autour de la chambre, la partie du tamis parallèle au câble de formation et opposée à ce dernier se déplaçant le long d'un trajet qui est sensiblement parallèle audit câble de formation. De plus, les éléments d'agitateur comprennent une pluralité d'axes rotatifs (47) qui sont parallèles les uns aux autres et orthogonaux au sens d'avancement (f3) dudit câble de formation.
