Abstract:
1. A 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 to provide spaced upstream and downstream filter face crests; each of said successive pleat flanks comprising a single plane having a first side and a second side manufactured to have minimal wave formation and being spaced by pairs of engaging adhesive increments of formed material of selected length applied to opposed sides of said successive pleat flanks that directly engage each of said first and second sides of each of said single plane at preselected distances from said filter face crests, said flank planes adjacently extending with said selected lengths centrally oriented between and spaced from said spaced upstream and downstream filter face crests, said first side having at least one of said adhesive increments of formed material and said second side having at least one of said formed material adhesive increments wherein said at least one of said adhesive increments of a first side of one of said successive pleat flanks engages said at least one said adhesive increments of second side of an adjacent said successive pleat flank each increment of said pair of adhesive increments having a longitudinal axis, said pair of longitudinal axes being substantially aligned on said at least one layer of fluid filter media.
