ABSTRACT:
A filter rod making machine is provided with an apparatus for applying plasticizer to a band of fibrous filter material wherein the application rate of the plasticizer is independent of the filter tow weight or width of the band passing through the apparatus. The plasticizer is added to the underside of the moving band by means of a rotatively mounted brush in rotating communication with a plasticizer supply source wherein the amount of plasticizer added to the band is dependent upon the amount of plasticizer metered by a constant volume pump. The rotatively mounted brush delivers liquid plasticizer in the form of a spray to the underside of the moving band. Variable changes in the level of the liquid plasticizer in the reservoir varies the amount of plasticizer being presented to the band, maintaining constant absorption rate regardless of tow band width.
