    The invention relates to a card with a garnished drum according to the preamble of claim 1.
    In modern high-performance carts, the component heating and the associated change in the spacing of the components plays an increasingly important role. So also the distance between drum and customer. In order to achieve a good quality at maximum production, this distance must be kept as constant as possible. However, the continued increase in the production of the new card generations also leads to clearer differences between the cold set nip and that in the warm state. So it can be e.g. In the area of polyester processing, it sometimes happens that the necessary cold setting for an optimum nip with a warm machine is so great that hardly any clean spinning can be achieved. Also, the technological result during the "warm-up phase" is significantly worse than with fully heated machine.
    When carding increasingly larger quantities of fiber per unit time are processed, resulting in higher speeds of the working organs and higher installed services. Increasing fiber material flow (production) leads to increased production of heat even if the working surface remains constant as a result of mechanical work. At the same time, however, the technological carding result (band evenness, degree of cleaning, reduction of the nissen, etc.) is constantly being improved, which means more carding surfaces and narrower settings of these effective areas, e.g. Fixed lid and / or revolving lid, due to drum (drum). The proportion of man-made fibers to be processed, in which - compared to cotton - in contact with the active surfaces (sets) of the machine generated by friction more heat, is steadily increasing. Today's high performance carder workplaces are fully enclosed on all sides to meet high safety standards, prevent particulate emissions into the spinning mill, and minimize machine maintenance requirements. Grates or even open, material-carrying surfaces that allow an exchange of air are largely a thing of the past. Due to the circumstances mentioned, the input of heat into the machine is significantly increased, while the heat loss by convection drops significantly. The resulting increased heating of high-performance carding leads to greater thermoelastic deformations, which influence the set distances of the active surfaces due to the unequal distribution of the temperature field: The distances between the drum and lid, pickup, hard covers and separation points decrease. In extreme cases, the set gap between the active surfaces can be completely consumed by thermal expansions, so that relatively moving components collide. Greater damage is then the consequence of the affected high performance deck. After all, in particular the generation of heat in the working area of the carding machine can lead to different thermal expansions if the temperature differences between the components are too great.
    Carding nips and roll distances are extremely important on the card. With an exact setting of this column (nip) stands the carding quality. Under the influence of heat, the rollers expand and the gaps change. To the expansions of the rollers by centrifugal force, which change the column strongly, high production and carding-intensive chemical fibers additionally provide for a strong heating of the rolls. There are thermally induced dimensional changes of the rolls. In order to achieve optimum carding quality, it is necessary that the roll distances remain constant during operation. Constant in this context means that the change in distance should preferably be less than 0.01 mm.
    In a known device (EP 1 300 494 B) comprises a discharge module a carrier. The axis of rotation of the pickup is fixedly arranged in the associated carrier. The carrier has a pivot axis which connects the carrier to a base plate of the frame. The carrier is pivotable about the axis between a standby position and a working position. In the working position of the outlet module, the customer has a predetermined distance (working gap) at the transfer position relative to the drum. The adjustment of the module about the pivot axis is accomplished by leverage between the axis and a respective adjustment location remote from the pivot axis. At each setting location is an adjusting mechanism (adjusting means), e.g. a screw. It can be provided any type of adjustable elements between the support and a stationary stop on the machine frame. The support structure for the drum consists of the aforementioned base plate, extending from side to side over the entire working width. At each end a support leg pair is attached and each pair of legs carries a respective end shield which receives the bearings for the drum shaft. In this apparatus, a predetermined working distance between the drum and the pickup before operation is set once with the adjusting mechanism (adjusting means) and maintained during operation. The working gap is set slightly larger in the cold state and decreases with increasing temperature of the drum and the adjacent roller to the desired level. A disadvantage is that in the cold state of the machine, the working gap is too large and only reaches the desired value when heated. When the card has to run from a standstill to process a certain amount of fiber flakes, the temperatures of the various parts of the machine continuously change over a period of time until a steady state (operating temperature) is finally reached. The "transient" period of these temperature changes is much longer than the start-up period itself. only reached after 1 to 5 hours. As a result, the quality of the card sliver in the warm-up phase is worse. In addition, the manufacturing process must be extremely precise. The set working gap is thus different in the cold and in the heated state of the machine. This difference is even more pronounced in the processing of various fiber materials, e.g. Cotton or chemical fibers.
    The customer cooperates with the downstream in the working direction Abstreichwalze. If the distance between the pickup and the drum is adjusted by the adjusting device, it may happen that the distance between the pickup and the doctor roller is also undesirably adjusted.
    The invention is based on the object to provide a card of the type described above, which avoids the disadvantages mentioned, which in particular is structurally simple and allows, in each position of the operation, the working gap between the user and the drum on the one hand and on the other hand, to keep the taker and skimmer substantially constant.
    The solution of this object is achieved according to the invention by a device having the features of independent claim 1.
    The dependent claims have advantageous developments of the inventive device to the subject.
    The invention will be explained in more detail with reference to exemplary embodiments illustrated in the drawings.

    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 flat bars 14, jug 15 and can stock 16. The directions of rotation of the rolls are shown with curved arrows. M1 denotes the center (axis) of the drum 4, M2 the center of the pickup 5, and M3 the center of the doctor roller 6. 4a indicates the clothing and 4b indicates the direction of rotation of the drum 4. 5a indicates the clothing and 5b indicates the direction of rotation of the pickup 5. With C is the direction of rotation of the revolving lid 13 in Kardierstellung and C is the Rücktransportrichtung the flat bars 14 and 17, 17 are stationary functional elements. The arrow A indicates the working direction.
    In Fig. 1a, the working distance between the set 4a of the drum 4 and the set 5a of the pickup 5 is denoted by a, and in Fig. 1b, the working distance between the set 5a of the pickup 5 and the set 6a of the skiving roller. 6 denoted by b.
    2, a side plate 18a of the drum 4 and a side plate 19a of the pickup 5 with a screw 21a (adjusting spindle) are coupled together. The screw 21a is supported at one end to a flange 22a, stop o. The like. Of the side plate 18a and with its other end to a flange 23a, stop or the like. of the side plate 19a. The screw 21a has at both ends of each screw on which nuts are assigned, and the flanges 22a and 23a each have through holes, which pass through the screw thread of the screw 21a. There is a stationary machine frame 24 (see Fig. 5a) on which the stationary side plate 18a is fixedly mounted. The drum 4 is also stationary. In addition, a rotary bearing 25 is fixedly mounted on the machine frame 24, around which the pickup 5 and the associated side plate 19a are pivotable in the direction of the arrows H, I (see FIG.
    The buyer is shown in FIG. 3 pivotally mounted about a fixed pivot point (pivot bearing 25) on the frame 24 of the machine. The rotary arm 34 of the pickup 5 is at one end to the spindle 21 a, metal rod or the like. tethered. The connection can e.g. via a (not shown) spherical disk, ball socket or the like. respectively. The other end of the spindle 21a is attached to the side plate 18a. When the side shield 18a expands radially due to heating, the spindle 21a is displaced substantially by the same amount and thereby rotates the lever arm 26 about the pivot point 25 in the direction of the arrow H. At the same time, the pickup 5 (and with it the side shield 19a , see Fig. 2) pivoted about the pivot point 25 by the same amount. In this way, the distance a between the tips of the clothing 4a of the drum 4 and the clothing 5a of the pickup 5 remains constant or substantially constant. In a corresponding manner, the pickup 5 is pivoted in the direction of the arrow I about the pivot point 25 when the side plate 18a is contracted as a result of cooling in the radial direction. The distance a remains constant or largely constant. In any case, the drum 4 and side plate 18a remain stationary.
    The drum 4 and the pickup 5 are provided on their cylindrical surface with a top set 4a and 5a, respectively. In the transfer of the fibers from the drum 4 to the pickup 5, the distance a between the cylindrical surfaces of both rollers is in addition to other parameters, e.g. the surface speed of both rolls and the type of top set crucial. Good working conditions between the rollers can only be secured if the distance a is kept within precise and very narrow tolerances. In this arrangement, the optimal value for the distance a, with roll diameters of about 0.20 m to 1.5 m and roll widths up to about 2 m, in a range of about 0.05 mm <a <0.3 mm, wherein the lower limit of the distance a is not technologically conditioned, but only to avoid mutual contact or disturbance of the clothing tips of both rolls is observed. Otherwise there is a risk of fire and mechanical damage of the expensive lace sets. The distance a is so extremely small in comparison to the roller dimensions. The increase in diameter caused by the increase in the roll temperature is, as determined by investigations, in the order of about 0.08 mm per 10 ° C temperature rise. By the device according to the invention a set in the cold state of the card optimum value of the distance a and the pickup 5 is maintained during operation.
    3, the holding device 26 for the skiving roller 6 - which may comprise further elements of the nonwoven decrease such as nip rolls 7, 8 (see Fig. 1) - rotatably mounted about a pivot bearing 27 in the direction of arrows K, L.
    At one end of a mounting rod 33, a shoe 28 is adjustably mounted. The fixing rod 33 is attached to the side plate 19 a of the pickup 5. The holding device 26 has, on the side facing the pickup 5, a sliding guide track 29, e.g. a concave arch. The outer contour of the shoe 28, e.g. formed convexly arcuate, is in operative contact with the sliding guide track 29 (see Fig. 3a).
    4, a coupling rod 30 is provided, which is pivotally connected at one end via a pivot bearing 31 on the side plate 19a of the pickup 5 and with its other end via a pivot bearing 32 on the holder 26 for the Vliesabnahme.
