A method of manufacturing a fluid filter comprising: (a) providing a cone (60) having a tip end and an open end and made of a filter material; (b) providing a support element (30) having a plurality of concentric annular members (70, 72, 74, 76) mounted on a base and having outermost (76) and innermost (70) concentric annular members; (c) aligning the central axes of the cone and the support element with the tip end of the cone closest to the support element; and (d) inserting a portion of the cone into a circular area between two concentric annular members by placing a forming sleeve (82, 84, 86, 88, 90) inside the cone and inserting the forming sleeve between the two concentric annular members, the concentric annular members being generally cylindrical and having an interior and an exterior. |
