A filter element for filtering a fluid stream, comprising a cylindrical support body, which is provided with openings and is sealed at one axial end, and a filter medium arranged on the support body. The filter medium is a strip material, which extends over approximately the entire length of the support body, and is wrapped around the circumference of the support body, and the start and the end of the strip material are welded together.

Filter element for filtering a fluid stream

A filter element composed of a nonwoven filter web of metal fibers affixed to a support body, in which the metal fibers of the filter web form an unsintered composite having a porosity of at least 90%. Preferably the metal fibers have a diameter of at most 4 &#x3bc;m.

Filter element, particularly for separating a liquid from a gas stream

An apparatus for forming a helical tube (,), including a first stamping station for producing a flange on a metal strip (,), a forming tool (,) in which the flanged metal strip is formed to a helical configuration and adjacent side edges are crimped together to produce a tube, a cutting arrangement (,) which cuts the tube into predetermined lengths, and a mechanical-optoelectronic measuring arrangement (,) for determining the length of the helical tube (,) to be cut.
