Abstract

PURPOSE: To prevent the loosening of a filter member and also the separation of the filter member from a frame by integrally forming a plastic frame on the periphery of the filter member.
CONSTITUTION: A plastic material, e.g., a mixture of polyurethane resin and polyisocyanate, is cast into the cavity of a casting mold 6, one sides 2 and 4 of filter members are put in the cast resin 3, and after the cast resin 3 is gelled, the filter members with the gelled cast resin 3 are removed from the casting mold 6 and allowed to stand until the cast resin 3 is hardened. Afterwards, the same operations are made for the other sides of the filter members in order to integrally form the plastic frame 3 on the periphery of the filter members.
