ABSTRACT:
A stream of filter tow which has been sprayed with atomized plasticizer is advanced past two detectors each of which monitors the density of the stream in a different way and generates corresponding signals which are processed by an evaluating circuit to generate modified signals which are indicative of the percentage of plasticizer. The modified signals are used to regulate the operation of a pump which controls the rate of admission of plasticizer to successive increments of the tow.
