Abstract

A method of making a filter cartridge, which has a filter element consisting of a filter leaf in one material and a cover of a second material, consists of warming one face of the cover until the surface is soft and applying the edge of the filter leaft under press. to the cover. The first material may be pleated paper and the second material polypropylene, polyethylene or polyamide. Alternatively, the first material may be vinyl chloride. The filter element may be an annular cylinder or made of stocked filter leaves. The method is cheaper and more convenient to operate than existing methods using an adhesive or a liq. thermohardening material.
