Definitions

  • the present invention relates to a cleaning device for pressure rollers of a combing machine which are pressed onto tear-off cylinders, in which two pressure rollers are located next to one another at least approximately the same height and above the tear-off cylinders to which they are pressed.
  • the pressure rollers used here are driven by the driven corrugating rollers in a constant direction of rotation during the stretching process via friction.
  • the printing rollers are cleaned using the cleaning rollers already described with a felt covering.
  • the cleaning of the corrugated rollers is carried out by means of cleaning rollers, which can consist of plastic with a smooth surface. These cleaning rollers are pressed against the surface of the corrugating rollers by means of a spring, the displacement of the cleaning roller being restricted by an appropriately arranged brake member.
  • the braking element also prevents the cleaning roller from being carried along by the friction between the corrugated rollers and cleaning roller. This means that during the wiping process the cleaning roller stops and the corrugated rollers turn.
  • a shaft of the corrugated rollers is provided with a driver, which engages at intervals in a gearwheel which is fastened coaxially on the cleaning roller. As a result, the cleaning roller is rotated intermittently against the braking effect in order to discharge the stripped components downwards.
  • such a device could also be used for wiping off the printing rollers, the cleaning roller being freely rotating.
  • a braking device is required in order to achieve a speed difference between the cleaning roller and the pressure rollers.
  • this is very complex and also prone to wear.
  • the task is to be solved to avoid the effort for cleaning work.
  • this is achieved by providing at least one cleaning roller which is parallel to the printing rollers, freely rotatable and has a smooth, non-fibrous outer surface and which rests on at least one of the printing rollers, their surface and that of the printing roller being of such a nature, that during operation of the combing machine, the cleaning roller slips on the pressure roller each time the direction of rotation changes.
  • Fig. 1 is a schematic representation of a combing roller, tear-off cylinders, pressure rollers and a cleaning roller, seen from the side and Fig. 2 shows another embodiment of the invention, also seen from the side.
  • the same reference numerals designate the same parts.
  • FIG. 1 shows a combing roller 11 with combing needles 12 attached over part of its circumference.
  • Lower pliers 13, upper pliers 14 and, in addition to these, a fixed comb 15 are provided.
  • a cleaning roller 19 freely rotatable about its longitudinal axis 18. It consists of a fibrous material, i.e. from a material to which the fibers do not adhere but from which they fall off easily. It has a smooth, polished outer surface.
  • the cleaning roller 19 is fixed at each of its ends by a guide 20 in its axial or longitudinal direction. The guides 20 allow free up and down movement of the axis 18 over the length of a vertical slot 21 present in the guide 20.
  • a band-shaped fleece 22 is held between the two pairs, each consisting of a cylinder 16 and a roller 17, and the pliers 13, 14.
  • the arrangement formed by the pliers 13, 14 and the fixed comb 15 can be moved back and forth against the cylinders 16 and rollers 17 into the position shown.
  • FIG. 2 there are again two tear-off cylinders 16 and two pressure rollers 17, by means of which a fleece 22 is held and conveyed from right to left.
  • a cleaning roller 19 rests on each printing cylinder 17.
  • These cleaning rollers are also freely rotatable about their axes 18. They are in turn fixed in their axial direction by guides 20 and freely movable in slots in these guides in the vertical direction.
  • a combing roller and pliers are not shown in this figure.
  • FIG. 1 In practice, an arrangement corresponding to FIG. 1 has proven itself, in which the combing machine worked at 350 comb strokes per minute.
  • the length of the pressure and cleaning rollers was 34 cm.
  • the cleaning roller had a diameter of 5 cm and its weight was 350 g.
  • Both the printing and cleaning rollers had a nitrile rubber surface.
  • the surfaces of the rollers were ground in the manner that is customary for printing rollers for spinning machines.

Claims (8)

  1. Dispositif de nettoyage pour des rouleaux de pression pressés contre des cylindres arracheurs d'une peigneuse, dans laquelle deux rouleaux de pression se trouvent au moins à peu près à la même hauteur l'un à côté de l'autre, et au-dessus des cylindres arracheurs, en étant pressés contre eux,

    caractérisé par le fait
    qu'au moins un rouleau nettoyeur (19) est prévu, parallèle aux rouleaux de pression (17), pouvant tourner librement et possédant une surface enveloppante lisse, sans adhérence avec les fibres, et qui repose au moins sur un des rouleaux de pression (17), la nature des surfaces du rouleau nettoyeur (19) et du rouleau de pression (17) étant telle qu'il se produit un glissement du rouleau nettoyeur (19) sur le rouleau de pression (17) à chaque changement du sens de rotation, pendant la marche de la peigneuse.
  2. Dispositif selon revendication 1,

    caractérisé par le fait que
    les rouleaux de pression (17) sont parallèles entre eux et le rouleau nettoyeur (19) repose sur les deux rouleaux de pression (17) par son propre poids.
  3. Dispositif selon revendication 1,

    caractérisé par le fait que
    le rouleau nettoyeur (19) est fixé dans son sens longitudinal, par des guidages (20) situés à ses deux extrémités.
  4. Dispositif selon revendication 1,

    caractérisé par le fait que,
    pendant la marche de la peigneuse, l'apparition de parcours de glissement ayant une importance désirée entre le rouleau de pression (17) et le rouleau nettoyeur (19) est réalisée par le choix du poids du rouleau nettoyeur (19).
  5. Dispositif selon revendication 1,

    caractérisé par le fait que
    que la surface enveloppante du rouleau nettoyeur (19) est constituée d'un caoutchouc naturel, d'un caoutchouc nitryle ou polychlorovinyle moux, ou similaire.
  6. Dispositif selon revendication 1,

    caractérisé par le fait que,
    a l'endroit de la surface enveloppante du rouleau nettoyeur (19) se trouve une couche de matière dont la dureté se situe entre 65° et 70° Shore.
  7. Dispositif selon revendication 1,

    caractérisé par le fait que
    la surface enveloppante du rouleau nettoyeur (19) et celle du rouleau de pression (17) sont constituées de la même matière.
  8. Dispositif selon revendication 4,

    caractérisé par le fait
    qu'un noyau est prévu à l'intérieur du rouleau nettoyeur (19) et sert à la détermination du poids et par cela de la pression d'appui du rouleau nettoyeur (19).
