Abstract
L'invention concerne un dispositif pour faire des filtres. Selon l'invention, il comprend un moyen 11 pour déplacer de l'étoupe d'un matériau fibreux et plastifié de filtrage 12 à travers une trajectoire prédéterminée ayant une partie 20 inclinée vers le haut; un moyen définissant un passage en forme d'entonnoir 13 disposé dans la partie 20 pour configurer l'étoupe en auge en U; un moyen 27 en aval du passage pour injecter une séquence de charges 15 de matériau particulaire dans l'auge ; un moyen 16 pour transporter une bande de papier d'enrobage 17 sous l'étoupe du matériau fibreux de filtrage; et une section de garniture 18 en aval du moyen d'injection pour enrober et sceller la bande de papier autour du matériau fibreux de filtrage et des charges injectées de matériau particulaire, afin de former une tige sans fin 35. L'invention s'applique notamment aux filtres pour cigarettes.
