The invention relates to a filtering device, comprising a tubular filter element and a carrier part, with the filter element fastened thereon. The carrier part can be inserted between an unfiltered fluid pipe and a filtered fluid pipe. The pipes can be assembled into a continuous flow pipe, wherein the filter element protrudes into the pipe interior.

Filtering device

The invention relates to a filter arrangement () for filtering a fluid, e.g. combustion air for a combustion engine. Said filter arrangement has several tubular sections or segments (). At least part of a wall () of at least one tubular section () comprises a filter material (B). At least one tubular section () is designed in a bendable manner like a folding joint (A).

Filter arrangement

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.
