Abstract
Method of coating or impregnating a guided web-shaped substrate with a flowable medium, which includes monitoring the composition of the flowable medium; continuously measuring the rate of travel of the substrate; applying a metered amount of flowable medium to the substrate at a given feeding point, corresponding to the monitored composition of the flowable medium and corresponding to the measured rate of travel of the substrate; continuously measuring the amount of flowable medium not yet accepted by the substrate; and regulating the transfer of flowable medium to the moving substrate corresponding to the measured amount of flowable medium to maintain a constant amount of flowable medium applied within pre-determined limits, and an apparatus for carrying out the method.
