Abstract: A method and apparatus for making axial-flow filters wherein a sectorial-shaped sheet of filter material having corrugations therein parallel to the curved ends thereof is made from a flat sheet of filter material, and thereafter the corrugated sheet is made into an annulus to obtain the final product. Initially, an edge portion of a flat sheet of filter material is attached to a sectorial-shaped mold, having a mold surface defined by curved ridges and valleys parallel to the curved ends of the mold, so that the sheet is slanted up away from the mold surface from the smaller curved end of the mold. Thereafter a set of curved forming blades is moved down toward the mold to engage the sheet and to fold it successively and consecutively across the ridges of the mold and beneath the edges of the blades into the valleys of the mold to corrugate the sheet. The corrugated sheet thus produced is made into an annulus by using a contouring belt which embraces the larger convexly curved ends of the sheet and constricts the sheet into an annulus. Thereafter the annular filter is reshaped by positioning a set of curved blades, corresponding to the valleys in one side of the filters, against the bottoms of these valleys and rotating the blades about the filter axis.

Abstract: A method and apparatus are disclosed for providing a crimp seal pleated filter assembly having a two piece housing with a filter media disposed within the housing and having a plurality of alternating pleats. The apparatus includes a first and second jig for supporting the housing halves and an odd number of at least three or more movable pleat forming blades on one side of the apparatus. The odd number of blades are movable through one of the supporting jigs with blade edges opposing the other supporting jig. The odd number of blades includes an independently movable center blade and a first pair of outer blades with opposing surfaces of adjacent blades defining a first plurality of pleat forming spaces. An even number of pleat forming blades are positioned with blade edges opposing the first plurality of pleat forming spaces and are spaced apart from and in alignment with the opposing pleat forming blades. The even number of pleat forming blades includes at least a pair of center blades which project through the other supporting jig during pleat formation and define a pleat forming space in which a first center pleat is formed. The blades and the jigs are moved toward one another in a predetermined sequence for the blades to form desired pleats within a filter media and for the jigs to urge the filter housing around the pleated filter media to crimp seal and encapsulate the media within the housing.

Abstract: At preferably circular filter cartridges, where pleated filter material is placed around a centrally arranged perforated tube, this filter material can be sucked to collapse if the pressure gradient through the material becomes large, whereby the advantages having a pleated filter cartridge with a relatively large filter surface and a very little volume are lost.One means for preventing such collapse is using a separator which is arranged in each pleat of the filter material, whereby the separator includes a rigid organic foil formed in a pyramidal pleating, the amplitude of this pleating increasing from zero in the edge of the pleat of the filter material to maximum at the centrally arranged perforated tube constituting the base of the pleat of the filter material. Manufacturing a light construction of a filter cartridge is hereby obtained which is able to resist pressure gradients up to a certain limit without being sucked to collapse.With the separators it is secured that the capacity of the filter is present during the lifetime of the filter independent of the pressure difference between outside and inside of the filter material.

Abstract: A refill filter cartridge for a liquid fuel filter includes a semi-rigid plastic "blister" having an open end closed by a cover member to define a fluid receiving compartment. A pleated paper filter medium in the compartment divides the latter into inlet and outlet portions which communicate with openings in the cover member. The filter housing includes a base and a cup-shaped glass housing that cooperates with the base to define a chamber which receives the plastic blister when the refill cartridge is installed in the filter. The cover member defines cooperating surfaces which engage the base and the glass housing so that the glass housing clamps the cover member between the glass housing and the filter base. The plastic blister is shaped to conform to the inner walls of the housing so that the housing engages the walls of the blister throughout their entire area. Accordingly, the glass housing serves as a support for the blister, so that the latter can withstand fluid pressure forces that would normally rupture the blister. In this way, a relatively inexpensive plastic blister can be used instead of a glass housing in the refill, and the filtering medium can be sealed to the sides of the blister instead of being sealed directly to the housing. Accordingly, the glass housing can be used over and over again, and need not be thrown away when the filter is changed.

Abstract: A conventional filter pleating machine has a laterally movable pusher bar and a vertically movable stripper bar parallel to it and normally spaced laterally from it above a table, with a vertically movable breaker bar between the other two bars and normally below the table top. The invention lies in providing the lower edges of the pusher bar and the stripper bar with a plurality of longitudinally spaced upwardly extending slots for receiving parallel separator tapes above a filter strip extending along the table beneath those two bars, and also in providing the upper edge of the breaker bar with longitudinally spaced downwardly extending slots for receiving parallel separator tapes below the filter strip when the breaker bar is raised, whereby the pleats in the filter strip will be separated by the separator tapes folded between them.
