ABSTRACT:
A process and apparatus for controlled application of a liquid to a variable width filamentary band such as a cigarette tow band. Liquid is fed at a constant rate by one or more positive displacement pumps to an applicator device which may be a disc type or a brush type applicator device. Any liquid which is not picked up from the applicator device by the tow band is returned by means of channels located in a housing member directly to the applicator device whereby variations in the width of the tow band do not substantially change tow liquid pick-up from a preselected weight level.
