  • 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 diverted to the fleece nozzle insert high-precision warped nonwoven, on the other hand the fibers in the nonwoven cover a greater distance than the ones in the inside, which are transported directly to the fleece nozzle insert. As a result, the fibers of the nonwoven are again, but this time undesirably, shifted against each other One consequence is that the parallelism of the fibers is deteriorated, especially with combed fiber bands

Arrows around the axis 411. Even in the event of a tape jam or the formation of rolls on the output rollers, the funnel 421 swivels from the operating position into its maintenance position, so that there is easy access to eliminate the fault.
  • the lower edge 427a of the funnel 421 rests on the block 409 and partially encloses a crater-like opening 430, into which a funnel insert (not shown) and subsequently a belt funnel can be inserted in the fleece running direction.
  • the difference in the pivotability compared to the embodiment according to FIGS. 1-5 is that only the funnel 421 is pivoted and not the subsequent elements (e.g. fleece nozzle insert, belt funnel).
  • the embodiments shown in the figures have in common that the fibers of the fleece V are each guided without abrupt deflections and thus to the respective outlet section in a gentle manner. This also applies to the impact of the fibers on the guide surfaces in the entry section of the respective fleece guide device; the fibers preferably meet the guide surface almost tangentially or at a very small angle.
  • the respective entry sections, guide surfaces and exit sections are each formed in one piece.
  • the guide surface forms a single element for itself and can be introduced into the space between the inlet and outlet sections, either fastened there or arranged movably, for example with the aid of a swivel mechanism.
