  • Fiber fleece or the fiber sliver formed from the fleece in the sliver funnel is pressed between the calender rolls and drawn off from the sliver funnel.
  • a disadvantage of the known construction is that fibers lying further outside in the fleece do not run directly into the fleece guide nozzle after leaving the drafting system, but rather hit the baffle surface of the fleece funnel at high speed, are folded in there and deflected to the fleece nozzle insert.
  • This abrupt impact on the one hand disturbs the previously precisely warped fiber fleece, on the other hand the fibers lying outside in the fleece cover a greater distance than the ones lying inside, which are transported directly to the fleece nozzle insert.
  • the fibers of the nonwoven are again, but this time undesirably, shifted against each other.
  • Another consequence is that the parallelization of the fibers is deteriorated, particularly in the case of combed slivers.
  • a textile machine according to the invention with a drafting system is characterized by a corresponding fleece guiding device.
  • the fleece guiding device is characterized in particular by the fact that outer fibers lead to the outlet section in a more direct way or with less detours than those lying further inside. All fibers of the nonwoven are preferably guided from at least one guide surface to the outlet section, so that the fibers lying inside are also guided, and not directly. The inside fibers are thus not transported in the shortest possible way from the exit rollers of the drafting system or a deflection top roller to the outlet section and further into a fleece nozzle section or a belt funnel.
  • the distance covered by the fibers lying further inside in the fleece is thus artificially lengthened so that an offset of the fibers of the fiber fleece between the drafting system outlet and the calender rolls is kept low or even avoided entirely. Accordingly, it is expedient to guide the fibers lying on the outside in an almost direct way or in a slight curve to the outlet section, while the central fibers located in the middle advantageously cover an arcuate path.

  • the guide surface advantageously extends following the output roller of the drafting system over the entire width of the fleece.
  • the lateral sections of the guide surface lead essentially straight to the exit section.
  • the corresponding surface section for the fibers lying inside is made concave or bulbous, the largest curvature being provided for the central or central fibers.
  • the fleece guiding device is advantageously arranged or can be arranged immediately behind the last drafting roller or the last pair of drafting rollers, so that the fibers can be guided immediately after they have left the drafting arrangement.
  • the fibers can also be guided continuously.
  • the direction of the fleece is inclined when leaving the drafting device with respect to the axis of the downstream belt funnel; for example, the drafting system is designed to be horizontal or inclined, while the belt hopper is oriented vertically.
  • the at least one guide surface according to the invention is preferably designed in such a way that on the one hand it realizes the corresponding deflection of the fleece and on the other hand completely avoids the fiber offset across the fleece width at least partially and in a particularly preferred case.
  • the drafting system is arranged vertically, so that, in the case of such conventional drafting systems, the fleece runs downward into the belt funnel without substantial deflection from the fleece plane (based on the direct exit from the drafting system). Accordingly, the configuration of the at least one guide surface according to the invention is to be adapted, which essentially has the task of at least partially avoiding the fiber offset.
  • the fibers can preferably be guided between at least two guide surfaces, wherein these can be arranged opposite one another or offset in the direction of the fleece.
  • at least part of the fleece can first be guided along one guide surface and then along the other guide surface.
  • the inner fibers of the fleece in particular are guided over a curved guide surface and thus deflected out of the way to the belt funnel until they are guided back to their original path to the belt funnel by a further downstream guide surface.
  • guide surfaces are preferably of this type formed and arranged that at least the inner fibers are guided along a concave guide surface at faster delivery speeds and substantially along a convex guide surface at lower delivery speeds.
  • the inner fibers leaving the drafting system are thus guided along the concave surface.
  • the inner fibers are not conveyed against this concave guide surface, but would move in a more direct way to the fleece nozzle. It is therefore advantageous to deflect these fibers from the other side at the low delivery speeds mentioned.
  • the inner fibers are preferably guided along the convex guide surface and in this way also reach the exit section in a deflected manner according to the invention.
