when a voltage is applied between the capillary or capillary holder and the substrate holder a droplet from which the spinning thread emerges is formed at the opening of the capillary in addition receptacles for the capillary and substrate are configured so that a relative positioning of the capillary opening with respect to the substrate surface is possible in a preferred embodiment the capillary can be positioned above the substrate by means of adjustment motors while in another embodiment it is possible with adjustment motors to position the substrate underneath the capillary during the spinning preferably the substrate is moved underneath the capillary in order to produce the desired conducting structures from the spinning liquid it should be ensured that the spinning process is stabilised in such a way that the resulting structure does not exhibit any breaks discontinuities on the surface preferably this is achieved by regulating the capillary distance relative to the substrate surface in which the forward movement of the line is interrupted by means of a regulating loop depending on a camera image if the spinning thread obviously breaks particularly preferably the procedure is stabilised by arranging for a computer to analyse the camera image and interrupt the relative feed movement of the capillary with respect to the substrate if the analysis shows a break in the continuous fibre the minimum voltage to be applied in the method varies linearly with the adjusted interspacing and also depends on the nature of the spinning liquid preferably an operating voltage of 0 1 to 10 kv should be employed for the spinning process so as to obtain a.
