ABSTRACT:
A spread out foraminous tow of tensioned filamentary filter material is transported through a housing between an upper and a lower rotating cylindrical brush. The upper brush propels atomized liquid plasticizer against the upper side of the tow whereby a certain amount of plasticizer penetrates through the tow and is gathered in the housing within the range of bristles on the lower brush which propels the gathered plasticizer against the underside of the tow. The rate of feed of plasticizer to the upper brush is varied in response to changes in the speed of the tow, and the brushes are arrested when the transporting rolls for the tow are brought to a standstill. The lower portion of the housing constitutes a trough which surrounds the lower half of the lower brush and from which the gathered plasticizer is evacuated when the brushes are idle.
