Summary: | PROBLEM TO BE SOLVED: To provide a method for surely fixing a filter element by preparing effectively the filter element to be inserted into a cup type container to be accurately inserted therein. SOLUTION: A filter material is folded in two adjacent layers which are connected to each other along a folded line of a bottom part while separable upper ends are provided. The adjacent layers are cut by pressure, the upper end is formed in a scalloped type pattern, and a carrier mandrel is inserted between the adjacent layers. The adjacent layers are bonded to each other along a joint running in a direction crossing the folded line of the bottom part to be connected to each other by a scrap part. Further, they are formed in a filter element F of a series of folded shaped truncated cone shape the inside of which is supported by the carrier mandrel. The filter elements F are separated from each other by pressure cutting and removing the scrap part. The separated filter element F is transferred into a cup type container C arranged below from the carrier mandrel, and the inserted filter element F is fixed to an inner surface of the cup type container C. |
