Abstract:
A device for creating a spread-out stream of tobacco fibers, comprising:a concave-curved guide track along which the fiber stream of tobacco fibers are conveyed, the guide track having a generatrix based on a uniform curve, a portion of the concave-curved guide track being formed by a convex sliding surface, the guide track having a width; and at least one air nozzle having an air flow interrupting the guide track so that air exiting the nozzle acts in a conveyance direction of the fiber stream for spreading cut the tobacco fibers, wherein the nozzle has a downstream wall, in relation to the conveyance direction of the fiber stream, which makes a transition into the guide track in a steady convex curvature, the at least one nozzle terminating in the sliding and extending continuously over the width of the guide track.
