    专利说明:

    The invention relates to a carding machine for cotton or man-made fibers with a device for guiding a fiber fleece according to the preamble of patent claim 1.
    A well-known card with such a device (DE 4 328 431 A) is in practice in high quantities trouble-free in business use and has found wide broadening. At a delivery speed of up to approx. 330 m / min, a profile closed as support and guide body is used. The upper, the skimmer roller facing top surface is closed and impermeable to air. At increased delivery speeds and also with a larger working width, disturbing air currents can act on the sensitive fiber web.
    The invention is therefore an object of the invention to provide a card of the type described above, which avoids the disadvantages mentioned, which allows in particular a simple way improved leadership of the batt, especially for larger working width and / or increased delivery speed.
    The solution of this object is achieved according to the invention by a carding machine having the features of independent claim 1.
    The dependent claims have advantageous developments of the inventive carding the subject.
    The invention will be explained in more detail with reference to exemplary embodiments illustrated in the drawings.<Tb> FIG. 1 <SEP> Side view of the card according to the invention (schematic),<Tb> FIG. 2 <SEP> enlarged side view of the supporting and guiding element of the card according to the invention according to FIG. 1, with a comb element,<Tb> FIG. 3 <SEP> Top view of the comb element according to FIG. 2, and<Tb> FIG. 4 <SEP> Perspective view of the comb element attached to a holding element.
    Fig. 1 shows a card, e.g. Trützschler card TC, with feed roller 1, dining table 2, lickerins 3a, 3b, 3c, drum 4, pickup 5, stripping roller 6, nip rollers 7, 8, fleece guide element 9, pile funnels 10, take-off rollers 11, 12, revolving cover 13 with cover deflection rollers 13a, 13b and top bars 14, jug 15 and can stock 16. With M, the center (axis) of the drum 4 is designated. 4a indicates the clothing and 4b indicates the direction of rotation of the drum 4. The arrow A indicates the working direction. The curved arrows in the rollers indicate the directions of rotation of the rollers. With 17 the inventive support and guide is called. Below the skiving roller 6, the inventive support and guide element 17 is arranged. The upper nip roll 7 is disposed adjacent to the skive roller 6, the lower nip roll 8 is substantially associated with the support and guide element 17.
    Fig. 2 shows that the support and guide element 17 has substantially an approximately triangular cross-section. The element 17 is mounted with its one end in an end-face end piece 18a and with its other end in an end-face end piece 18b (see FIG. The element 17 consists of two parts, a comb element 19 and a holding element 20 for the comb element 19. The comb element 19 is arranged below the skiving roller 6 and forms the upper surface of the supporting and guiding element 17. The upper surface is cleaned by the fiber material sliding over it , eg from Trash.
    The upper surface 19 (see Fig. 3) of the comb member 19 is the (not shown) garniture of the skiving roller 6 faces. The comb element 19 is assigned with its one end region 19 to the nip between the pickup 5 and the doctor roller 6. The other end portion 19 is disposed in the region between the skiving roller 6 and the nip rollers 7, 8, wherein the end portion 19 is aligned in the direction of the nip between the nip rollers 7, 8. The retaining element 20 is an extruded profile, e.g. made of aluminium.
    According to Fig. 3, the length I of the comb member 19 is e.g. 1300 mm and more. The comb element 19 extends over the entire length of the skiving roller 6 and the nip rolls 7, 8 (i.e., across the entire width of the card). It has in the end region 19 unilaterally open prongs 19a to 19n, wherein between two adjacent prongs 19a to 19n each unilaterally open narrow slits 20a to 20n are. The open ends of the prongs 19a to 19n and the slots 20a to 20n point in the direction of the fiber material run. Air passes through the slots 20a to 20n. As a result, disturbing air currents are at least partially eliminated. The comb element 19 is suitably electrolytically polished in order to avoid fiber adhesion.
    4, the comb member 19 is fixed to the holding member 20, wherein the comb member 19 and the holding member 20 at the end-side mounted end pieces 18a and 18b (in Fig. 4 is shown only 18b, 18a is shown in Fig. 2 ) are stored.
    The inventive card has the particular advantage that on the one hand, the upper surface of the support and guide element 17 with her - as seen in the working direction A - front range comes close to the nip between the nip rollers 7, 8 and on the other hand from the space between the squeezing rollers 7, 8 and the skimmer 6 disturbing air currents down, ie through the space between support and guide element 17 and lower squeegee 8, are derived. This lower space may communicate with a suction device.
