Abstract
A method for the continuous monitoring of the coating of a yarnlike dielectric material with assistants comprises applying a solution of said assistants dissolved in a polar solvent to said yarnlike material, then passing said yarnlike material between the electrodes of a downline capacitive measuring element, determining the capacity changes of said downline capacitive measuring element, and using said capacity changes to calculate the unevenness of the layer thickness of the applied solution.
