Title (EN) SYSTEMS AND METHODS FOR PROVIDING SHAPED VACUUM PORTS FOR FLUID EXTRACTION VACUUM BOX COVERS IN PAPERMAKING SYSTEMS
(FR) SYSTÈMES ET PROCÉDÉS DE FOURNITURE D'ORIFICES D'ASPIRATION EN FORME POUR COUVERCLES DE CAISSES ASPIRANTES D'EXTRACTION DE FLUIDE DANS DES SYSTÈMES DE FABRICATION DE PAPIER
Abstract:
(EN) A system is disclosed for removing fluids from a felt in a paper making process. The system includes a vacuum source for providing a vacuum adjacent a vacuum plate against the felt is moved, and crescent shaped openings in the vacuum plate through which the vacuum is applied to the felt for the removal of the fluids.
(FR) L'invention concerne un système d'élimination de fluides d'un feutre lors d'un processus de fabrication de papier. Le système comprend une source de vide destinée à établir un vide au voisinage d'une plaque aspirante contre laquelle est amené le feutre, et des ouvertures en forme de croissant ménagées dans la plaque aspirante par l'intermédiaire desquelles le vide est appliqué au feutre à des fins d'élimination des fluides.
