Claim 9:
10. The method according to claim 1, wherein
the step of axially compressing the filter medium further includes:
axially compressing the filter medium of the annular pleated filter medium body to form a second compressed section arranged adjacent to but spaced axially inwardly away from an opposite axial end face by a distance of maximally 5 mm, forming a second uncompressed free region of the filter medium between the second compressed section and the opposite axial end face;

wherein the step of forming a second end disk is practiced by:
applying the flowable plastic material in a flowable state onto the second uncompressed free region of the annular filter medium body such that the second compressed section forms a barrier separating the flowable plastic material from an axially inward uncompressed region of the annular pleated filter medium body;
curing or hardening the flowable plastic material on the opposite axial end face of the annular pleated filter medium body, forming the second end disk.
