CA 2361500

A filter forming and joining apparatus of the present invention automatically forms a succession of metal-free cylindrical filter elements from a pleat block of pleated filter material, each pleat block (112) having a first end pleat at a first end of the pleat block and a second end pleat at a second end of the pleat block. The apparatus including a pleat block isolator (300) for isolating successive individual pleat blocks from other pleat blocks in a succession of pleat blocks in preparation for filter formation, a filter former (400) that manipulates each isolated pleat block along a forming path into a hollow cylinder shape, the hollow cylinder-shaped isolated pleat block having a first end pleat and a second end pleat positioned adjacent each other, and a filter joiner (500) that bonds together the adjacent first and second end pleats of each hollow cylinder-shaped isolated pleat block producing a metal-free cylindrical filter element.

L'invention concerne un appareil de formation et d'assemblage de filtre qui forme automatiquement une suite d'éléments de filtrage cylindriques dépourvus de métal à partir d'un bloc de plis d'une matière de filtre plissée, chaque bloc de plis (112) comprenant un premier pli d'extrémité au niveau d'une première extrémité du bloc de plis et un second pli d'extrémité au niveau d'une seconde extrémité du bloc de plis. Cet appareil comprend un dispositif d'isolation (300) servant à isoler les blocs de plis successifs d'autres blocs de plis dans une suite de blocs de plis en cours de préparation afin de former un filtre, un dispositif de formation (400) de filtre qui donne une forme cylindrique creuse à chaque bloc de plis isolé le long d'un chemin de formation, ce bloc de plis isolé en forme de cylindre creux comprenant un premier pli d'extrémité et un second pli d'extrémité adjacents l'un à l'autre, et un dispositif d'assemblage de filtre (500) qui lie les plis d'extrémité adjacents de chaque bloc de plis isolé en forme de cylindre creux, créant ainsi un élément de filtre cylindrique dépourvu de métal.
