Abstract

Le dispositif tampon et compacteur pour nappe fibreuse multicouche non consolidée (N) comporte une première (21) et une deuxième (20) bandes de transport sans fin qui sont enroulées sur des rouleaux de guidage selon un trajet fermé, et un chariot (24) qui est mobile en translation dans deux directions opposées (A ; B). Au moins un premier rouleau de guidage (214) est commun aux deux bandes de transport (20, 21) et est embarqué sur le chariot (24). Au moins un (201) des rouleaux de guidage de la première bande de transport sans fin (21) est un rouleau moteur permettant d'entraîner la première bande de transport sans fin (21) à une vitesse d'entrée Ve(t). Au moins un (202) des rouleaux de guidage de la deuxième bande de transport (20) sans fin est un rouleau moteur permettant d'entraîner la deuxième bande de transport sans fin (20) à une vitesse de sortie Vs(t) qui peut être différente de la vitesse d'entrée Ve(t). Les bandes de transport sans fin (20, 21) permettent de déplacer en translation le chariot (24) dans l'une ou l'autre des deux directions (A,B) en fonction du différentiel entre les vitesses d'entrée Ve(t) et de sortie Vs(t), de manière à augmenter la longueur de parcours de la nappe dans le dispositif lorsque la vitesse d'entrée Ve(t) est supérieure à la vitesse de sortie Vs(t), et à diminuer la longueur de parcours de la nappe dans le dispositif lorsque la vitesse d'entrée Ve(t) est inférieure à la vitesse de sortie Vs(t).

The buffer and compactor device for unconsolidated multilayer fibrous web (N) comprises a first (21) and a second (20) endless conveyor belt which is wound on guide rollers in a closed path, and a carriage (24) which is movable in translation in two opposite directions (A; B). At least one first guide roller (214) is common to the two conveyor belts (20, 21) and is loaded on the carriage (24). At least one (201) of the guide rollers of the first endless conveyor belt (21) is a drive roll for driving the first endless conveyor belt (21) at an entry speed Ve (t). At least one (202) of the guide rolls of the second endless conveyor belt (20) is a drive roll for driving the second endless conveyor belt (20) at an output speed Vs (t) which can be different from the input speed Ve (t). The endless conveyor belts (20, 21) make it possible to move the carriage (24) in translation in one or other of the two directions (A, B) as a function of the differential between the input speeds Ve (t ) and output Vs (t), so as to increase the travel length of the web in the device when the input speed Ve (t) is greater than the output speed Vs (t), and to reduce the length of course of the web in the device when the input speed Ve (t) is lower than the output speed Vs (t).
