Title (EN) FILTER MANUFACTURING APPARATUS
(FR) APPAREIL DE FABRICATION DE FILTRE
Abstract:
(EN) The present invention relates to a filter manufacturing apparatus comprising: • a feed path adapted to continuously feed a filter material along a longitudinal transport direction; • a forming device connected to a terminating end of the feed path and adapted to form the filter material into a continuous filter body and to deliver the formed continuous filter body, the forming device including: • a tubular element (8) adapted to allow the filter material to pass therethrough to form the filter tow material into the continuous filter body; and • a steam generator (9) adapted to produce steam, the steam generator being in fluid communication with the tubular element to supply steam to the filter material; • a drain channel (10) in fluid communication with the tubular element adapted to drain fluid from the tubular element; • a valve adapted to open and close the drain channel so as to allow or block discharge of fluid from the tubular element.
(FR) La présente invention concerne un appareil de fabrication de filtre comprenant : • un trajet d'alimentation adapté pour acheminer un matériau de filtre de manière continue le long d'une direction de transport longitudinale ; • un dispositif de formage relié à une extrémité terminale du trajet d'alimentation et adapté pour former le matériau de filtre en un corps de filtre continu et distribuer le corps de filtre continu, le dispositif de formage comprenant : • un élément tubulaire (8) adapté pour permettre au matériau de filtre de passer à travers ce dernier pour former le matériau de cordon de filtre en corps de filtre continu ; et • un générateur de vapeur (9) adapté pour produire de la vapeur, le générateur de vapeur étant en communication fluidique avec l'élément tubulaire pour fournir la vapeur au matériau de filtre ; • un canal d'évacuation (10) en communication fluidique avec l'élément tubulaire adapté pour évacuer un fluide depuis l'élément tubulaire ; • une soupape adaptée pour ouvrir et fermer le canal d'évacuation de façon à autoriser ou bloquer l'évacuation de fluide depuis l'élément tubulaire.
