Abstract: From an endless, flat metal strip are cut at least two tapes (1,3), or an integral multiple of two. The metal is of good conductivity of magnetic flux. The strip width is adapted to that of two tapes, or less, and the strip thickness is adapted to the required tape thickness. From the strip are cut-out at least two tapes of identical size, and from each tapes are stamped out isosceles triangles (2D,3D) at preset points with defined opening angle and height. In the inner apex of each triangle is made a hole (2L,3L) with preset cross-section.
