Abstract
Plasticizer or other fluid additive is applied to a moving filter tow in an applicator chamber by means of a rotary brush. Uncaptured plasticizer is collected in a container and returned to the chamber for reapplication. The rate of initial application is controlled by a pump and that of reapplication by a restrictor valve; the rates are independently variable. The supplied and collected plasticizer may be applied to different parts of the tow, e.g. to different sides.
