Definitions

  • the invention relates to a device for increasing the adhesive length of fiber tapes according to the preamble of main claim 1.
  • the sliver represents an intermediate product in the spinning process, which is formed for the first time after the card. It is used for submission or further processing on the subsequent spinning machines.
  • DE-OS 33 19 514 shows a pair of toothed rollers for transporting a sliver.
  • the tooth height is relatively large, which means that the sliver can dodge.
  • US Pat. No. 3,328,851 shows a draw frame with a sliver, the sliver being delivered to a funnel wheel for slivering via a pair of toothed calender rolls.
  • the toothing shown, or the profile of the toothing has a large profile depth or tooth height. This is to create a device that works with low vibration at a high depositing speed and can react quickly to excessive material accumulation between the two calender rolls. As can be seen in particular from FIG. 5 of this citation, the teeth also act directly on the inner fibers of the sliver due to the deep profile and thereby also change the parallel structure of the fibers in the core of the sliver. However, this is not technologically desirable for the subsequent processing of the slivers on a spinning machine.
  • the invention is therefore based on the object of providing a device for increasing the adhesive length of fiber slivers, the increased adhesive length being retained for the next processing stage and the action taken on the fiber sliver not adversely affecting the parallel position of the fibers for the subsequent processing process affects and does not damage the fibers.
  • the flat rise of the tooth flank also has an advantageous effect. In this way, deposits of contaminants in the depressions are avoided and the individual fibers are treated gently.
  • a depression of 0.5 mm has proven to be advantageous. Sufficient crimping of the fibers is thereby achieved without having an adverse effect on the parallel alignment of the fibers.
  • the sliver 1 is fed to a compressor hopper 3 via a conveyor belt 2.
  • the sliver 1 emerging from the compressor hopper 3 passes between the calender rolls 4 and 5 and is then deposited into a can 7 via a rotating funnel wheel 6.
  • the calendar rollers 4, 5 are each provided with lateral guide flanges 8, 9 which project beyond the rollers in diameter and carry out a lateral guidance of the sliver 1 clamped between the calendar rollers 4 and 5.
  • the roller 5 is pivotally mounted about the axis 10.
  • This pivoting movement is pivoted in by an adjustable stop 12 which is fastened to the pivoting tube 13 of the roller 5.
  • an adjustable stop 12 which is fastened to the pivoting tube 13 of the roller 5.
  • a hand lever 15 is fastened to the swivel tube 13 to swivel the roller 5 away, for example when threading in a new sliver 1.
  • the calender rolls 4 and 5 are provided with tooth-like elevations 16 on their outer circumference. These elevations 16 are of identical design in the case of both rollers 4, 5, so that they can mesh with one another like with spur gear teeth.
  • the stop 12 is set so that the distance a ( Figure 3) is always greater than zero. This is to avoid damage or wear to the rollers 4, 5.
  • the elevations 16 on the tip circle diameter D1 and root circle diameter D2 are rounded off with the radii R1 and R2.
  • the flank 17 of the elevation 16 runs relatively flat, the angle being greater than 45 degrees. This results in a particularly gentle treatment of the sliver and prevents damage to the individual fibers during the pressing process.
  • the guide flange 9 has been omitted in the illustration according to FIG. 3 for reasons of clarity.
  • the calender roll 4 is fixedly mounted on the machine frame 14 and is driven by a drive, not shown in detail.
  • the calender roll 5 is freely rotatably mounted in the swivel tube 13.
  • the roller 5 is also rotated by the driven roller 4 via friction.
  • the operation of this facility is as follows: The sliver 1, which is fed via the conveyor belt 2, passes through the funnel 3 into the press point P between the calender rolls 4, 5.
  • the sliver 1 or the fibers are slightly crimped and changed from an exactly parallel alignment to a wavy alignment.
  • This device is particularly suitable following a combing process, the strip having very short adhesive lengths after combing out, soldering and stretching.
  • This increase in the adhesive length substantially reduces the risk of a belt break in subsequent processing machines and may enable belt transport over a longer feed path, or direct feeding to the subsequent processing machine without intermediate storage in a can.

Claims (5)

  1. Dispositif pour augmenter la longueur d'adhésion de rubans de fibres (1), particulièrement de rubans de fibres textiles qui sont délivrés par des machines de filature traitant des fibres textiles (comme par exemple des peigneuses) dans un récipient (7) ou directement dans une machine suivante de filature, et où le ruban de fibres (1) est guidé en passant entre deux rouleaux calandreurs (4, 5), dont au moins un des rouleaux calandreurs (5) est maintenu chargé par un ressort dans la direction de l'autre rouleau calandreur (4), et les deux rouleaux calandreurs (4, 5) sont pourvus d'élévations (16) en forme de dents, dirigées transversalement, sur leur circonférence extérieure, qui exercent la force de pression sur le ruban de fibres (1), vu dans le sens de la circonférence, et qui peuvent s'engrener l'une dans l'autre comme une roue dentée,
    caractérisé par le fait que,
    en regardant le profit, les élévations en forme de dents (16) s'élèvent de 0,3 mm à 0,8 mm, et l'angle (α) compris entre le flanc (17) de la dent et la radiale passant au milieu de la dent est plus grand que 45°.
  2. Dispositif selon revendication 1,
    caractérisé par le fait que
    les élévations (16) sont pourvues d'arrêtes arrondies.
  3. Dispositif selon revendication 1 ou 2,
    caractérisé par le fait que
    l'élévation est de 0,5 mm de préférence.
  4. Dispositif selon l'une des revendications 1 à 3,
    caractérisé par le fait que,
    par rapport aux axes des rouleaux calandreurs, la tête de dent de chaque élévation est pourvue d'un arrondi en forme d'arc de cercle convexe et le pied de dent est pourvu d'un arrondi en forme d'arc de cercle concave, arrondis dont les rayons (R1, R2) correspondent à l'importance de la hauteur de dent.
  5. Dispositif selon revendication 1,
    caractérisé par le fait que
    les rouleaux calandreurs sont pourvus de flanges de guidage latérales (8, 9), faisant saillie au-dessus du diamètre du rouleau, afin de guider latéralement le ruban de fibres (1).
