    A carding machine for cotton or man-made fibers comprises a device, which device is arranged between a pickup (5) and two nip rolls (7, 8) of the carding machine below a stripping roller (6) arranged between the pick-up (5) and the two nip rolls (7, 8). the card is arranged. The device comprises a supporting and guiding element (17) arranged fixedly below the doctoring roller (6), whose upper surface faces a region of the doctor roller (6) and whose front surface faces a lower squeezing roller (8) of the two squeezing rollers (7, 8) is. In the support and guide element (17), an edge is aligned between the upper surface of the support and guide element (17) and the front surface of the support and guide element (17) in the direction of a nip between the nip rolls (7, 8), wherein a non-woven fabric over the upper surface and then to the nip between the two nip rolls (7, 8) can pass through a free space. The front surface of the support and guide member (17) facing the lower squeeze roller (8) is formed such that a gap formed between the front surface of the support and guide member (17) and the lower squeeze roller (8) widens downward so that a in the space between the support and guide element (17), the skiving roller (6) and the nip rolls (7, 8) existing air flow (B) opposite to the direction of rotation (8a) of the lower nip roll (8) through the gap can be discharged ,

    专利说明:

    The invention relates to a carding machine for cotton or man-made fibers with a device for guiding a nonwoven fabric on a carding machine for cotton or man-made fibers, according to the preamble of 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 front, the lower nip facing surface of the element is flat. 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 guidance 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:
    It shows:<Tb> FIG. 1 <SEP> Side view of the card according to the invention (schematic),<Tb> FIG. 2 <SEP> the support and guide element of the inventive carding in section and<Tb> FIG. 3 <SEP> enlarged side view of the supporting and guiding element of the card according to the invention according to FIG. 1with aerodynamically trained, the lower nip rollers facing surface.
    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.
    Fig. 2 shows that the support and guide element 17 has substantially an approximately triangular cross-section. The upper surface 17 is slightly curved concave. The radius of curvature of the curvature of the surface 17 is greater than the radius of curvature of the surface of the doctor roller 6. The arrow A indicates the running direction of the (not shown) nonwoven fabric. The front end portion has an edge 171, the rear end portion 172 is rounded. The edge 171 avoids the deposition of contaminants, e.g. Honeydew. The surface 17 is cleaned by the nonwoven passing over it, e.g. from Trash. The cross-sectional shape of the element 17 is adapted to the air flow conditions in the region between the pickup, the doctor roller and the nip rollers 7, 8. The rear surface is designated 17.
    According to Fig. 3, the upper surface 17 of the element 17 of the (not shown) clothing of the skiving roller 6 faces. The element 17 is assigned with its one end region to the nip between the pickup 5 and the doctor roller 6. The other end portion is disposed in the area between the skiving roller 6 and squeezing rollers 7, 8, the edge 171 being aligned in the direction of the nip between the squeezing rollers 7, 8. The element 17 is an extruded profile, e.g. made of aluminum, with an internal cavity.
    As shown in FIG. 3, the lower nip 8 facing area 17 (front surface) of the support and guide member 17 is concave, so that the air flow B is directed against the rotation direction 8a of the lower nip roller 8. The gap between the front surface 17 and the lateral surface 8b of the lower nip roll 8 expands downwards approximately conically. This allows a certain nozzle effect, which favors the discharge of the air flow B.
    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.
