Definitions

  • the invention relates to a nonwoven card according to the preamble of claim 1.
  • the invention has for its object to improve a generic Vlieskrempel to the effect that the most versatile and effective influencing of the air jet is possible.
  • the invention proposes to adjust not only one but both walls of the air shaft.
  • both walls can be pivoted about an axis which is parallel to the axis of the main cylinder, or the two walls can be moved together in parallel, so that the air duct is moved virtually opposite to the spool and the tangential impingement of the air on the spool on this Way is influenced, so that in particular the area in which the fibers are thrown off the spool, can be influenced and in this way the further fiber flow can be influenced up to the storage belt.
  • an adjustable air duct 2 which leads tangentially air to a spool 3 and is bounded by two walls.
  • a tambourferne wall 4 of the air shaft 2 is, as indicated by the double arrow in the drawing, together with a lower roller 5 laterally adjustable.
  • Within the air shaft 2 is located just before the air reaches the drum 3, an air divider. 6
  • the tambournahe wall 7 of the air shaft 2 is also adjustable laterally together with a skimmer 8, as also indicated by a double arrow. Due to the adjustability of the haul-off nose, the fiber jet of textile fibers, which are conveyed on the spool in the gap between the spool surface and the illustrated carding segment 9 and possibly existing carding segments (not shown), is influenced so that the fibers either rest even longer on the spool, after they have passed the haul-off nose 8, or that the fiber jet is farther away from it flies, so that the separation point at which the fibers leave the tambour can be influenced.
  • the detachment generally begins at the end of the carding segment 9, ie when the fibers have arrived at the end of the carding segment 9 shown on the right. There begins a Abschleuderkanal 10, which extends to the skimmer nose 8. The corresponding end of the carding segment 9 is marked A, which denotes the Abschleuderddling.
  • the air divider 6 is adjustable together with the Abschleudernase and the tambournahen wall 7 of the air shaft 2.
  • the fibers are deposited evenly distributed on an air-permeable storage belt 11 when the tape runs counter to the direction of the air flow, ie in the direction of the arrow indicated on the right on the storage belt 11.
  • the inclination of the storage belt 11 where the fiber jet occurs on the storage belt 11, so the angle between storage belt 11 and the fiber jet, can be influenced by an adjustable guide roller 12, wherein together with the guide roller 12, a sealing member 14 can be adjusted so this as close as possible to the storage belt 11 is guided.

Claims (4)

  1. Carde à tambour enrouleur (1),
    avec un tambour guidant des fibres le long d'une partie de sa circonférence,
    et avec une bande de dépôt perméable à l'air qui reçoit les fibres éjectées du tambour,
    et avec une gaine d'air acheminant de l'air de façon approximativement tangente au tambour,
    dans laquelle la gaine d'air est délimitée par deux parois disposées l'une derrière l'autre dans le sens de transport des fibres en formant une paroi proche du tambour et une paroi éloignée du tambour,
    caractérisée en ce que les deux parois (4, 7) de la gaine d'air (2) sont réglables.
  2. Carde à tambour enrouleur selon la revendication 1, caractérisée en ce qu'il est prévu dans la gaine d'air (2) un diviseur de flux d'air (6) qui peut être déplacé en même temps que la paroi proche du tambour (7).
  3. Carde à tambour enrouleur selon la revendication 1 ou 2, caractérisée en ce que la bande de dépôt (11) est orientée en oblique par rapport au flux d'air et circule dans un sens de transport opposé au flux d'air.
  4. Carde à tambour enrouleur selon l'une des revendications précédentes, caractérisée en ce qu'un ergot d'éjection (8), qui forme l'extrémité d'un interstice entre le tambour (3) et au moins un segment de carde (9), peut être déplacé en même temps que la paroi proche du tambour (7) de la gaine d'air (2).
