Abstract
A device for creating a spread-out stream of tobacco fibers includes a concave-curved guide track along which the fiber stream of tobacco fibers are conveyed. The guide track has a generatrix based on a uniform generating curve. At least one air jet has an air flow opening interrupting the guide track so that air exiting the air flow jet acts in a conveyance direction of the fiber stream for spreading out the tobacco fibers.
