摘要： A filter cartridge having pleated filter material, the ends of which are joined together to form a conical tube. At least one band is bonded to the pleated filter material and extends at least partially around the circumference of the material in the area of each of its end sides. The band may be bonded to crease points of the filter material. A method of manufacturing the filter cartridge includes providing the initially strip-shaped, planar filter material with pleats. The pleated strip-shaped filter material is laid out forming an unwound cone-shaped shell. A band is placed onto the crease points of one side and is bonded to the crease points. Subsequently, the filter material is bent to form a conical tube, and the tube is closed upon itself by joining the two ends together.
