Title (EN) A METHOD AND APPARATUS FOR DEPOSITING PARTICLES ON A MOVING WEB OF MATERIAL
(FR) PROCEDE ET APPAREIL PERMETTANT DE DEPOSER DES PARTICULES SUR UNE BANDE DE TISSU MOBILE
Abstract:
(EN) An arrangement for depositing particles to a moving material web (6), the arrangement including a particle dispenser (3, 4) and a perforated belt (5) which moves over the material web. According to the invention, the particle dispenser (3, 4) is intended to dispense particles continuously in a uniform and wide flow whose width is equal to or somewhat greater than the width of the hole-pattern of the belt and the belt is spaced at a distance from the material web which is at least sufficiently large for the particles (13) deposited on the material web (6) to be accommodated between the belt (5) and the web (6). The arrangement also includes means (15, 16) which function to remove particles (14) caught by the belt without the particles falling down onto the underlying material web. These means are located downstream of the particle dispenser. The invention also relates to a method for depositing particles to a moving material web.
(FR) Système permettant de déposer des particules sur une bande de tissu mobile (6). Le système comprend un distributeur de particules (3, 4) et une courroie perforée (5) se déplaçant au-dessus de la bande de tissu. Selon l'invention, le distributeur de particules (3, 4) est prévu pour distribuer en continu des particules dans un flux uniforme et large, dont la largeur est égale à ou quelque peu supérieure à la largeur du réseau de trous de la courroie. La courroie est placée au-dessus de la bande de tissu à une distance suffisamment grande pour permettre la réception des particules (13) déposées sur la bande de tissu (6) entre la courroie (5) et la bande (6). Le système comprend des moyens (15, 16) destinés à retirer les particules retenues par la courroie sans que celles-ci tombent sur la bande de tissu sous-jacente. Ces moyens se trouvent en aval du distributeur de particules. L'invention se rapporte également à un procédé permettant de déposer des particules sur une bande de tissu mobile.
