Abstract
Apparatus for applying fluid additive to a stream of fibrous material such as a filter tow. The apparatus provides structure for blowing air into the filter tow during or immediately after the application of the fluid additive, a plasticiser; this foams and distributes the plasticiser in the tow. Air may be delivered from a porous plate closely adjacent to the path of the tow or from nozzles in an air injecting unit. Alternatively air may be used to foam plasticiser at a location remote from the tow and foamed plasticiser subsequently conveyed to and into the tow by a roller.
