Improved apparatus and method for installing a filter sleeve (10) in fil- tration apparatus (12) is provided. In its basic form the present invention uses a filter sleeve with a pre-installed end cap (18) bonded to at least one of its ends. Through use of a bonding process such as sonic welding, the end cap (18) and filter (10) sleeve form a tight seal with one another which is durable and quite resistant to leakage. The end cap can be provided with receptacles to allow for ready inter- face with existing filtration apparatus, elimination presently utilized mount- ing procedures which can be ineffec- tive burdensome, and time consum- ing. Additionally improved method is also provided for securely sealing the opposite end of the filter sleeve.
Dispositif et procédé perfectionnés de montage de manchons de filtres (10) dans une installation de filtrage (12). On utilise à cet effet un manchon de filtre comportant un obturateur préinstallé (18) soudé à au moins l'une de ses extrémités. Grâce à un procédé de soudage tel que le soudage à ultrasons, l'obturateur (18) et le manchon de filtre (10) forment entre eux un joint hermétique qui est durable et très résistant aux fuites. L'obturateur peut être pourvu de réceptacles assurant une interface aisée avec l'installation de filtrage existante, ce qui élimine les procédures de montage classiques, qui peuvent être inefficaces, onéreuses et longues à exécuter. On décrit également un procédé amélioré de fermeture hermétique de l'autre extrémité du manchon de filtre.
