  • Patent number: 8707527
    Abstract: A method for providing coil shaved metal fibers according to the present invention comprises the steps of -providing a metal composite foil, the metal composite foil comprising oat least two metal layers (Lx) for being converted into metal fibers, each pair of adjacent metal layers are mutually separated by a sacrificial layer (Sy) provided from a sacrificial metal, each sacrificial layer (Sy) having a first and second surface, whereby for each sacrificial layer, the first surface contacts one of the pair of adjacent metal layers, the second surface is contacting the other of the pair of adjacent metal layers; -coiling said metal composite foil on a shaft thereby providing a metal coil having one free end surface; -rotating the metal coil and cutting the free end surface of the metal coil by means of a cutting tool, thereby providing a bundle of composite fibers; -removing the sacrificial metal of the sacrificial layers from the composite fibers thereby providing a bundle of metal fibers, each metal fiber bei

  • Patent number: 8596033
    Abstract: A new metal fiber yarn (1) and methods for obtaining such a yarn are provided. The metal fiber yarn comprises at least 9 bundles (8) of continuous metal fibers. Each of the bundles comprises at least 30 metal fibers (7). The at least 9 bundles are arranged in at least 2 layers of continuous metal fiber bundles as seen over a transverse cross section through the metal fiber yarn. This new metal fiber yarn has an increased flexlife and strength.

  • Patent number: 8474236
    Abstract: A new metal fiber yarn is provided. The metal fiber yarn (10) constitutes a construction comprising continuous metal fibers (13) forming a metal fiber yarn. The construction comprises at least 5 bundles (12) of continuous metal fibers twisted together to form a yarn. Each of the metal fiber bundles (12) comprises at least 30 metal fibers (13). The yarn comprises at least one partial yarn (11), said partial yarn comprising at least two metal fiber bundles (13) twisted around each other with a predetermined number of torsions per meter.

  • Publication number: 20080248230
    Abstract: An electromagnetic shielding housing is presented that is made up out of one or more shells. The shells comprise polymer and conductive fibres and have a polymer rich surface that covers the fibres except for predefined areas where the fibres are substantially uncovered. The conductive fibres can be metal-coated non-metallic fibres or plain metallic fibres, preferably plain stainless steel fibres. A method for uncovering the fibres is also presented which comprises the breaking-off of selected protrusions or the breaking of the shell at selected recesses so as to uncover the fibres. The housing and the method solve the problem that the polymer skin leads to inferior shielding at the joint of the shells.
