Abstract

In oscillation circuits made by a cylindrical connecting membrane product with frequencies below the rated frequency, and interconnected with at least one common connecting membrane, for the adjustment of the frequency range of oscillation circuits consisting of a connecting metal - synthetic material - metal membrane for identification labels, under almost continuous movement through two frequency measuring cells 5,6 with one shortening unit 7 between them and via the comparison of rated / actual values, the frequency range of an oscillation circuit is adjusted after shortening the capacitor segment of that oscillation circuit, and assisted by the shortening unit 7 which is set by the correction unit 8. The position of the shortening unit 7 which is set by the correction unit is used as the baseline value when setting up the shortening unit 7 for a subsequent oscillation circuit; hence, for the final setting of the shortening unit 7 and in order to shorten the next oscillation circuit, only minimal corrections should be necessary. The method is applicable when the connecting membrane does not need, after selectively choosing the constituent elements and their dimension, intense aberrations of the frequency in oscillation circuits that are not too far away one from the other.
