Filter tow comprising crimped spun fibers and/or filaments is prepared in a preparation zone and fed to a processing zone where it is gathered, in an intake zone, then wrapped and cut into tobacco smoke filter rods. In the region of the intake zone, a gas or vapor under elevated pressure acts on the filter tow at an angle of less than 90 DEG to the longitudinal axis of the filter tow in the direction of movement of the filter tow. The relevant apparatus includes a preparation unit and a processing unit, the latter unit for feeding a gas or vapor under elevated pressure to the filter tow in the direction of movement thereof including: an intake finger (14) having holes (17) in the wall thereof on the filter tow intake side, or a pipe (22), whose gas or vapor exit end 23 terminates in the region of the filter tow outlet side of the intake funnel (23) or the filter tow intake side of the intake finger (14), or a blowing device (27) immediately upstream of the filter tow intake side of the intake finger (14).
