The regenerator has a central axis. The regenerator comprises a multitude of web layers wound around the central axis. The web layers are formed by two or more metal fiber or metal wire comprising webs wound around the central axis. When observed from the central axis to the outside of the regenerator, at least one web layer of a web of a first width is followed by a web layer of a web of a width larger than the web of a first width. |
