Abstract
Certain embodiments of the invention may include filters and methods for imparting structural support to a pleated filter material. According to an example embodiment, the method includes forming a filter structure from one or more sections of pleated filter media, wherein the filter structure comprises one or more filter pleats. The method also includes extruding a banding material to form one or more radial support regions in at least circumferential contact with at least one of an inner or an outer surface of the filter structure, and maintaining spacing between the one or more filter pleats of the filter structure with the one or more radial support regions.
