Definitions

  • the invention relates to a method for producing sliver from fiber material with the characteristics of the generic term of Claim 1, and a device for performing this Procedure.
  • a method is already known from DE 33 15 909 A1 for the production of nonwovens, in which by means of a Width distribution measuring system, an evaluation and Control, the air flow in a hopper like this is influenced that a good material distribution across Direction of travel and thus uniform card template reached becomes.
  • a method according to the preamble of claim 1 takes place in spinning technology application to match fuses with very to produce a small running meter weight. This was through Subdivide the filling shaft into a number of partial shafts and thus by dividing the corresponding in the Filling chute fed flake sample into individual Original strips reached.
  • the to change an air passage cross section through the measuring device can be controlled cover device, just like the air outlet itself, any one Have training.
  • a special technical The simplicity of the construction is here Subject of claim 3.
  • Fiber flakes 14 are supplied by means of conveying air.
  • the filling shaft 10 is a processing device 16, for example in the manner of a card. Of further this is for example in four by partitions 18, 20, 22 separate shafts 24, 26, 28 and 30 divided, in each of which one Flake template builds up.
  • the partial shafts are thus removed by means of take-off rollers 32 24 - 30 a total of four strip-shaped flake patterns 34, 36, 38 and 40 simultaneously off and together in the card 16 moved in. Accordingly, the card 16 also fall on the output side four strip-shaped flake patterns, which then processed into matches 42, 44, 46 and 48 become.
  • the conveying air can pass from the sub-shafts 24 - 30 an air passage provided in its lower area 50, which is preferably formed by a flat sieve, flow out again.
  • This sieve extends in the essentially over the entire width of the shaft and over one certain range of the height of the sub-shaft concerned.
  • the supplied fiber flakes 14 are stored in the lower area of the sub-shafts 24 - 30, whereby inevitably a column of material with approximately uniform Fiber distribution builds up.
  • a cover member 52 is assigned to the outside of the shaft by means of an actuator 54 of any design stepless up to essentially complete Release or down to essentially complete Closure of the sieve 50 is adjustable. For the sake of simplicity is only one of these actuators 54 drawn.
  • Each fuse is used to determine the sliver meter weight 42 - 48 by means of a measuring device 56, 58 assigned to it 60 and 62 passed through each one of the Actuators 54 for the slider 52 can be controlled.
  • each measuring device 56-62 has one Control line 64 with that actuating device 54 connected, the slide 52 of that sub-shaft is assigned, whose flake template to form the measuring fuse is provided. For the sake of simplicity only one of these control lines 64 is shown.
  • Controlled variables and corresponding control of the slide 52 is therefore the one to comply with the particularly low Match cord weight required per running meter Fiber density of the individual, strip-like flake patterns 34 - 40 by influencing the deduction of the Conveying air from sub-ducts 24 - 30 can be influenced, although all flake patterns 34 - 40 together in the Card 16 to fiber pile and then to individual sliver 42 - 48 are processed.

Claims (3)

  1. Procédé de fabrication d'une mèche en matière fibreuse, dans lequel la matière fibreuse (14) est envoyée de manière pneumatique vers une cuve de remplissage (10) divisée en une pluralité de cuves partielles (24, 26, 28, 30) disposées selon une rangée et dont la paroi de cuve comporte, dans sa zone inférieure, à chaque fois, une traversée d'air (50) destinée à l'évacuation de l'air de transport, et dans lequel les formations de flocon (34, 36, 38, 40), en forme de bande, qui sont extraites des cuves partielles (24, 26, 28, 30) individuelles, sont, après avoir traversé ensemble un dispositif de traitement (16), tel qu'une cardeuse ou une machine à carder, transformées en mèches individuelles (42, 44, 46, 48)
       caractérisé en ce que
       pendant la formation des mèches, on mesure, de manière continue, la masse des mèches par mètre courant de chaque mèche individuelle (42, 44, 46, 48) et en ce que, pour des écarts de poids par rapport à un poids de consigne, afin de corriger le poids, on modifie, de manière correspondante, la section transversale de la cuve partielle qui fournit la formation de flocon à la cuve partielle concernée.
  2. Dispositif pour la mise en oeuvre du procédé selon la revendication 1, comportant une cuve de remplissage (10) divisée en une pluralité de cuves partielles (24, 26, 28, 30) disposées selon une rangée et dont la paroi de cuve comporte, dans sa zone inférieure, à chaque fois, une traversée d'air (50) destinée à l'évacuation de l'air de transport, et comportant un dispositif de traitement (16), tel qu'une cardeuse ou une machine à carder, caractérisé en ce que la traversée d'air (50) de chaque cuve partielle (24, 26, 28, 30) peut être agrandie ou rétrécie, de manière continue, en fonction du poids par mètre courant mesuré de la mèche (42, 44, 46, 48) produite à partir de la formation de flocon (34, 36, 38, 40) de la cuve partielle, et en ce que, à cet effet, l'on adjoint à chacune des cuves partielles (24, 26, 28, 30), en aval du dispositif de traitement (16) qui leur est associé en commun, un dispositif de mesure (56, 58, 60, 62) destiné à la mesure du poids par mètre courant de la mèche et au moyen duquel on peut commander un dispositif de réglage (54) d'un dispositif de recouvrement (organe de recouvrement 52) de la cuve partielle (24, 26, 28, 30) adjointe à ce dispositif de mesure (56, 58, 60, 62).
  3. Dispositif selon la revendication 2, caractérisé en ce que le dispositif de recouvrement comporte un organe de recouvrement (52) qui peut être déplacé selon une direction parallèle à un crible constituant le passage d'air.
