Abstract

A method of forming and inserting filter elements into cup-shaped containers comprises the steps of:a) folding a continuous web of filter material into two adjacent plies which have separable upper edges and are joined one to the other along a bottom fold line;b) blanking the adjacent plies to form their upper edges into a scalloped pattern;c) inserting carrier mandrels between the adjacent plies;d) joining the adjacent plies along seams extending transversely with respect to the bottom fold line to form a series of collapsed frustoconical filter elements interconnected by scrap segments and supported internally by the carrier mandrels;e) separating the filter elements one from the other by blanking and removing the scrap segments;f) transferring the filter elements from the carrier mandrels into cup-shaped containers arranged therebeneath; andg) securing the thus inserted filter elements to interior surfaces of the cup-shaped containers.
