A process for producing nonlinear resistance tracks on a supporting base uld be carried out in such a way that constant transitions are provided between the nonlinear resistance sub-ranges. For this purpose the supporting base is moved under a coating device at right angles to the longitudinal direction of the base strips provided whereby this coating device applies several strips of resistance paste onto the supporting base in the wet condition so that they are close to each other. The resistance pastes have different resistance values according to the set non-linear resistance pattern. The base strips are cut out of the supporting base at right angles to its direction of movement.
