Definitions

  • the compacted original fiber band then enters the clamping region formed by the sliver feed cylinder and the feed trough, which is usually wider than the original fiber tape. In this way it is ensured that the original fiber tape is securely clamped even in the edge areas.
  • a tuftstring is arranged with lateral webs following the clamping area.
  • the lateral webs also prevent uncontrolled lateral emigration of the original fiber ribbon due to the helical arrangement of the sawtooth.
  • the invention is based on the recognition that at the high rotational speed of the teeth of the opening roller set, a ventilation effect is created by the circulating air flow, which hinders the penetration of the tuft into the opening roller set. This effect is particularly cumbersome if a sudden increased fiber supply, as occurs at the beginning of an effect in the yarn, the opening roller is offered.
  • the solution according to the invention ensures the forced penetration of the tuft first into the ventilation flow, which already favors the extraction of the fibers from the tuft, and the rapid and complete detection of the offered large amount of fiber through the opening roller set. On the one hand, this is ensured by the transition area, as close as possible to the opening roller, to the support surface, but in particular the continuous gap reduction between the support surface and the tips of the dissolving roller set.
  • the feed trough 8 is mounted movably limited to a pivot axis 16 and is acted upon by a (not shown) spring element in the direction of the arrow 17 opposite to this direction of movement.
  • the feed trough 8 has a concavely curved clamping region 11 and a likewise concavely curved support surface 13 for the tuft.
  • a convexly rounded transition region 14 is arranged whose radius r is less than 2 mm.
  • lateral guide lugs 12 are provided which prevent emigration of the original fiber tape 4 during the combing out of the original fiber tape 4.
  • the original fiber tape 4 is brought as close as possible in the region of the tips 20 of the opening roller 3 by the clamping portion 11 of the feed tray 8 and is fixed by a support surface 13.
  • the extremely small radius r of the transition region 14 causes the distance C between the transition region 14 and the tips 20 of the opening roller 3 here is only 3 mm, that is, the free gusset between the clamping portion 11, the support surface 13 and the tips 20 of the opening roller 3 is minimized.
  • the support surface 13 of the feed trough 8, starting from a combing point K is increasingly brought closer to the tips 20 of the opening roller set 3.
  • the gap width A at the Einklammddling K is 1 mm.
  • the gap width B which results at the end of the gap after an angle range W of 40 ° in the direction of rotation of the opening roller, is 0.3 mm.
  • Fig. 4 shows a feed trough according to the prior art.
  • a planar guide surface 19 incorporated into the support surface 13 adjoins a transition region 14, which is delimited by lateral guide walls.
  • a free gusset which has a negative impact, especially in the production of effect yarn, since the original fiber tape accumulates there in the acceleration phase of the sliver feed 8 and then not resolved clean.

  1. Auge d'alimentation (8) pour un dispositif de défibrage des rubans de fibres d'un métier à filer à fibres libérées, comprenant une zone de serrage (11) concave coopérant avec un cylindre d'alimentation (7) des rubans de fibres, pour transporter un ruban de fibres (4) qui alimente la machine, des parois de guidage latérales pour guider le ruban de fibres (4) alimentant la machine, ainsi qu'une surface d'appui (13) courbée de façon concave pour immobiliser une mèche de fibres peignée par un cylindre défibreur (2), l'auge d'alimentation (8) pouvant pivoter autour d'un axe de pivotement (16) parallèle à l'axe de rotation du cylindre défibreur (2), caractérisée en ce que l'auge d'alimentation (8) est conçue et disposée en position de travail de telle manière qu'il se forme, au niveau d'un point de départ du peignage K, entre la surface d'appui (13) et les pointes (20) adjacentes de la garniture (3) du cylindre défibreur, une largeur de fente A comprise 0,7 et 1,5 mm, qui se réduit progressivement à une largeur de fente B ≤ 0,5 mm sur une zone angulaire W d'au moins 30° dans le sens de rotation du cylindre défibreur (2), et en ce que, dans le sens inverse au sens de rotation du cylindre défibreur (2), l'augmentation de la largeur de fente jusqu'à une zone de transition (14) entre la surface d'appui (13) et la zone de serrage (11) est essentiellement juste telle que l'on évite un contact avec les pointes des dents (20) lorsque l'auge d'alimentation (8) pivote autour de l'axe de pivotement (16) dans le sens inverse au sens de rotation du cylindre défibreur (2).
  2. Auge d'alimentation selon la revendication 1, caractérisée en ce que l'auge d'alimentation (8) présente, dans la zone de transition (14), une courbure convexe d'un rayon r ≤ 2,0 mm.
  3. Auge d'alimentation selon la revendication 1 ou 2, caractérisée en ce que des saillies de guidage (12) latérales pour le ruban de fibres d'alimentation (4) sont disposées dans la zone de transition (14) à courbure convexe.
  4. Auge d'alimentation selon la revendication 3, caractérisée en ce que les saillies de guidage (12) latérales s'étendent uniquement sur la zone de transition (14).
  5. Auge d'alimentation selon l'une des revendications 1 à 4, caractérisée en ce que, dans la zone de transition (14), la largeur de fente prend la valeur C ≤ 4 mm.
  6. Auge d'alimentation selon la revendication 1, caractérisée en ce qu'à partir du point de départ du peignage K et sur l'ensemble de la zone angulaire W, le rayon que forment les pointes (20) de la garniture (3) du cylindre défibreur correspond au rayon de courbure de la surface d'appui (13), et en ce que, pour faire passer la largeur de fente de A à B, le centre M1 pour la courbure de la surface d'appui (13) est décalé de façon correspondante par rapport au centre de rotation M du cylindre défibreur (2).
  7. Auge d'alimentation selon la revendication 1, caractérisée en ce que l'auge d'alimentation (8) est réalisée d'une seule pièce et est revêtue d'une couche anti-usure au moins dans les zones (11, 13, 14) dans lesquelles passent des fibres.
