    An apparatus for detaching and combining a fibrous web emerging from a delivery mechanism of the device into a sliver on a carding machine comprises a guide element (9), which adjoins the delivery mechanism of the device, which comprises a nip roller pair (7), over the entire length (I ) of the nip rolls of the nip roller pair (7) has at least one non-moving guide surface (9a) with a passage opening (9b). The guide surface (9a) of the guide element (9) forms a channel whose open side essentially covers the approximately triangular space between the pair of nip rollers (7), wherein a rounded guide element (17a, 17b) at the end region of the channel assigned to the passage opening (9b) 17b) is arranged.

    The invention relates to a device for removing and summarizing a leaking from a delivery mechanism of the device batt to a sliver on a carding machine according to the preamble of claim 1.
    In a known device (EP 0 775 768 A) the squeezing rollers a funnel-like element is arranged downstream, whose input is assigned to the nip roller and its output to the input rollers of a drafting system. The distance between the drafting system with the funnel-like element and the squeeze roller pair is inversely proportional to the working speed of the card changeable by a displacement device. The distance can also be changed depending on the other parameter as well as during the operation of the machine. This known device is complex in terms of investment. It also disturbs that interfering air currents from above and / or below and from the sides act on the batt due to the distance of the funnel-like element of the nip rolls.
    The invention is therefore an object of the invention to provide a device of the type described above, which allows in particular a simple way improved management of the batt of the nip rolls for trimming funnel, especially for larger working width and / or increased delivery speed.
    The solution of this object is achieved according to the invention by a device having the features of independent claim 1.
    Characterized in that the guide surface of the guide element forms a (open on one side) channel, the vertical and horizontal guidance of the pile is improved. The pile is controlled by the squeeze rollers to the trimming funnel. In order to realize high delivery speeds, disturbing air currents are kept away from the pile. To this end, the open side of the channel closes across the width of the approximately triangular space between the nip rollers. The cavity of the channel is thereby associated near the emerging from the nip fiber pile.
    The dependent claims have advantageous developments of the invention 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 device according to the invention on a card, shown schematically,<Tb> FIG. 2a to 2c <SEP> side view of the guide element of the device according to the invention in the working direction two nip rolls, arranged downstream in different embodiments,<Tb> FIG. 3 <SEP> Top view of the guide element according to FIG. 2a corresponding to sections I-I, and<Tb> FIG. 4 <SEP> perspective view of a further embodiment of the guide element with guide elements.
    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. The upper take-off roll 11 rotates counterclockwise and the lower take-off roll 12 rotates clockwise.
    According to Fig. 2a to 2c is the squeezing rollers 7, 8 downstream of a guide element 9, which is open in the direction of the squeezing rollers 7, 8, to receive the (not shown, emerging from the nip across the width) fibrous web. The batt slides along the fixed guide surface 9a. The open side of the guide element 9 covers the approximately triangular space between the pair of nip rollers 7, 8 substantially. The squeezing rollers 7, 8 are arranged downstream of guide elements 9 with a different embodiment, namely elliptical (FIG. 2 a), folded (FIG. 2 b) or prismatic (FIG. 2 c).
    In operation of the squeezing rollers 7, 8 leaving batt on the guide surface 9a meets in such a way that the batt is rolled about like a pleat. As a result, the batt is summarized and deducted by the directions determined by the direction of rotation of the draw-off rollers 11, 12 directions. The gathered fibrous web is led around rounded guide elements 17a, 17b (see Fig. 3, 4) for deriving from the guide surface 9a and brought together in the sliver funnel 10 to form a sliver (not shown).
    According to Fig. 3, the length I of the nip rolls 7, 8 is e.g. 1300 mm and more.
    The guide element 9 extends over the entire length of the nip rolls 7, 8 (i.e., over the entire width of the card). It has, in the region of the withdrawal point, a through opening 9b which opens into the pile funnel 10, in which the incoming fibrous web is compacted into a sliver. The guide surface 9a has in each case from the roller bearings 19a, 20a (19b, 20b not shown) to the opening 9b towards - on average - a rising shallow inclination angle. The guide surface 9a may be flat or may be concave or convex. The contour of the guide surface 9a can also be composed of several circular arc sections. The two areas of the guide surface 9a associated with the opening 9b (passage opening) are bulged in the direction of the nip rolls 7, 8 and form two rounded guide elements 17a, 17b. The guide elements 17a, 17b are integrated in this embodiment in the guide surface.
    Fig. 4 shows an embodiment of the guide element according to Fig. 2b, which is folded as seen in cross-section. The guide element 9 has two guide surfaces 9a1und 9a2auf. Between the two end regions of the guide surfaces 9a1 and 9a2 associated with the opening 9b and the entrance of the opening 9b there are in each case a rounded guide element 18a or 18b, e.g. in the form of a bolt o. The like., Arranged. The longitudinal axis of the guide elements 18a, 18b extends substantially perpendicular to the longitudinal axis of the nip rollers 7, 8. The guide elements 18a, 18b are in the illustration of FIG. 4 separate components.
