Abstract

In a method for stabilizing folded filter media, a thread is coated with a hot melt adhesive to prepare a coated thread. The coated thread is wound in a plastic state about fold tips of a folded filter medium. The plastic state of the coated thread is maintained by applying heat. The heat is applied in the form of hot air, infrared radiation, or generated by microwaves.
