CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This patent application is a divisional patent application of, and claims priority to and benefit from, currently pending, U.S. patent application Ser. No. 10/748,365, filed on Dec. 30, 2003. BACKGROUND OF THE INVENTION [0002] The present invention relates to fluid filter media and more particularly to a unique and novel arrangement for uniformly forming and spacing the pleats of pleated filter material and a novel unified pleated filter product produced by the inventive method set forth herein. [0003] Various arrangements are known in the filtration art for forming pleated filter media material and spacing the successive pleats in geometrically configured planar and cylindrical cartridges produced by such forming arrangements. In this regard, attention is directed to some of the prior art noted in the related co-pending U.S. patent application Ser. No. 10/317,437, filed on Dec. 12, 2002 by Kyung-Ju Choi. More specifically, attention is directed to the pleat spacer arrangement of U.S. Pat. No. 3,531,920, issued to C. G. Hart on Oct. 6, 1970 and to the spaced incremental spacer arrangement of U.S. Pat. No. 5,071,555, issued to K. Enbom on Dec. 10, 1991 wherein the spacer increments successively align in spaced relation between adjacent pleat flanks to space the same. Further attention is directed to the embossed spacer and dimple arrangements of the respective U.S. Pat. No. 5,290,447, issued Mar. 1, 1994, to H-J Lippold and U.S. Pat. No. 5,306,321, issued on Apr. 26, 1994, to R. J. Osendorf. Further attention is directed to the cartridge filter configuration of U.S. Pat. No. 5,427,597, issued to R. J. Osendorf on Jun. 27, 1995. Further, attention also is directed to the several different method arrangements for forming pleated filters as are disclosed in U.S. Pat. No. 5,804,014, issued to K. Kahler on Sep. 8, 1998; and to the four patents issued to Kyung-Ju Choi, namely, U.S. Pat. No. 6,159,318 on Dec. 12, 2000; U.S. Pat. No. 6,165,242, issued Dec. 26, 2000; U.S. Pat. No. 6,254,653, issued Jul. 3, 2001; and U.S. Pat. No. 6,398,839, issued Jun. 4, 2002. Finally, attention is directed to the several incremental pleat spacer arrangements disclosed in U.S. Patents issued to H. J. Lippold, namely: U.S. Pat. No. 5,028,331, issued on Jul. 2, 1991; U.S. Pat. No. 5,053,131, issued on Oct. 1, 1991; U.S. Pat. No. 5,066,319, issued on Nov. 19, 1991; U.S. Pat. No. 5,089,202, issued Feb. 18, 1992; and to Pub. No. U.S. 2002/003324 A1, published Mar. 21, 2002. [0004] None of these aforedescribed several patents however discloses or even suggests the unified, unique, novel, straight-forward, efficient and economical method and apparatus involving pleating and spacing adjacent successive flanks of adjacent pleats to provide uniformly extending selected V-shaped pleat spacing arrangements with selected geometric configurations and with a minimum of parts and a minimum of steps, optimizing performance characteristics with reduced pressure drops and even further effectively utilizing and inventively adding to the know-how of prior arrangements including, but not limited to, those set forth in the aforedescribed patents and co-pending patent application. [0005] In accordance with the present invention, a unified, unique and novel filter arrangement including a method and product is provided to allow for efficient and low pressure drop fluid filtration operations--particularly air filtration--and for ready formation of selected planar and/or cylindrical geometric configuration with readily selected spacing arrangements between adjacent pleat flanks. [0006] Various other features of the present invention will become obvious to one skilled in the art upon reading the disclosure set forth herein. BRIEF SUMMARY OF THE INVENTION [0007] More particularly the present invention provides a unique and novel method of manufacturing a pleated fluid filter including opposed upstream and downstream filter media faces comprising: feeding from a supply zone at least one layer of filter media to a scoring zone to provide spaced score lines on the layer of filter media; feeding the scored layer of filter media to a spacer application zone to selectively form thereon increments of material spaced in such a manner that the formed increments become communicatively facing when the scored layer of filter media is subsequently fed to a pleating zone; and, feeding the filter media with the selectively spaced and formed increments to a pleating zone to be pleated into a plurality of pleats successively spaced by the cumulatively facing increments, the pleating zone including reciprocating feed means to produce planar pleat flanks with minimum wave formation. [0008] In addition, the present invention provides a unique pleated fluid filter arrangement comprising: at least one layer of fluid filter media pleated into a plurality of longitudinally extending adjacent opposed successive pleat flanks of selected depth and spacing between successive pleat flanks having minimal wave formation to provide spaced upstream and downstream filter face crests; the successive pleat flanks being spaced by communicatively facing increments of spacer formed material increments extending in selected lengths between the spaced upstream and downstream filter face crests. [0009] It is to be understood that various changes can be made by one skilled in the art in the several steps of the inventive method and in the several parts of the unified inventive product as described herein without departing from the scope or spirit of the present invention. For example, steps other than as described herein can be employed in the formation of the fluid pervious filter media and in the composition and arrangement of the communicatively facing increments of spacer formed material including the shaping of the engaging surfaces of the facing increments of spacer formed material. BRIEF DESCRIPTION OF THE DRAWINGS [0010] Referring to the drawings which schematically disclose several embodiments of the present invention: [0011] FIG. 1 is a flow diagram schematically disclosing structure utilized in carrying out one or more embodiments of the several steps of the inventive method to produce a unified inventive product; [0012] FIG. 2 is an additional flow diagram schematically disclosing a portion of the structure of a further arrangement of the present invention wherein filtration material fed from a supply roll is further treated as in the aforementioned related co-pending application before reaching the scoring zone of FIG. 1; [0013] FIG. 3 is an isometric view of a portion of a sheet of filter media after it has passed both the scoring zone and the spacer material forming application zones; [0014] FIG. 4 is an isometric view of the portion of the sheet of filter media of FIG. 3 after it has passed the pleating zone, disclosing a portion of the sets of cumulatively facing formed spacer increments; [0015] FIGS. 5 and 5A are portions of a geometrically formed cartridge-type filter arrangement embodiment also disclosing a portion of sets of the cumulatively facing formed increments spacers. [0016] FIGS. 6 and 6A disclose plan views of two embodiments of portions of filter material including formed sets of spacer material increments, the facing increments being of substantially similar length and of substantially uniform cross-section in FIG. 6, and being of differing cross-section and in pleated form in FIG. 6A wherein the combined increments are tapered to provide tapered spacing with an overall geometric configuration conducive for use in the cartridge filter arrangement of FIG. 5; [0017] FIGS. 7 and 7A disclose plan views of still another embodiment of a portion of filter material including formed sets of spacer material increments in cumulative overlapping condition; [0018] FIGS. 8 and 8A disclose plan views of another embodiment of sets of overlapping cumulative facing formed spacer increments of similar cross-sectional thickness but of different lengths forming a geometrically planar-type filter arrangement; [0019] FIGS. 9 and 9A disclose plan views of another embodiment of sets of selected overlapping cumulative facing formed spacer increments also of similar thickness but of different lengths capable of forming a geometrically cylindrical type filter arrangement; [0020] FIGS. 10A, 10B and 10C are schematic illustrations in the pleating zone illustrating the unique and novel feeding movement of the filter media as it is formed into pleats, the schematic feeding movement following a substantially "back and forth" or vertically "up and down" reciprocating feed motion pattern between the to be formed upstream and downstream pleat crests as the filter media is fed into the pleating zone so as to minimize undesirable pleat flank wave formation; Continue reading...
