Abstract:
1. A method for providing coil shaved metal fibers, comprising: providing a metal composite foil, the metal composite foil comprising at least two metal layers (Lx) for being converted into shaved metal fibers, said at least two metal layers being adjacent and defining a pair of adjacent metal layers, each pair of adjacent metal layers being 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, and 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 using a cutting tool, thereby providing a bundle of composite fibers; and removing the sacrificial metal of the sacrificial layers from the composite fibers thereby providing a bundle of metal fibers, each metal fiber being obtained from one of the metal layers (Lx).
