  • FIG. 1 shows a revolving flat card, for example the Rieter card C60 with a working width of 1.5 m. Fiber flakes are transported through transport channels through the various Putzereireamen (not shown) and finally filled the hopper 16 of the card.
  • the shaft 16 in FIG. 1 is designed as a so-called "cleaner shaft” with a cleaning module between the shaft top and the manhole base. However, this is not essential for the present invention, instead of a cleaner shaft and a normal hopper can be provided.
  • the shaft then passes the fiber flakes to the card as cotton wool, namely to a known feed device, which feeds the cotton into the card at a predetermined speed.
  • the feeder feeds the fiber flakes to the lickerins 3.
  • the lickerins open the fiber flakes and remove some of the debris.
  • the last licker-in roller passes the fibers to the card drum 1. After the fibers have in part performed several revolutions on the card drum, they are removed by the pickup 4 from the card drum, fed to the discharge area 5 and finally deposited as a card sliver in a cane stick in a jug ( Not shown).
  • the carding drum 1 is provided with a clothing, usually a presege leopardgarnitur (not shown), and it cooperates with the cover 7 of a revolving flat unit 2 during the forward flow of the covers 7 together.

  • the revolving flat aggregate 2 consists of 79 to 112 lids, which are combined by a chain or a belt to form a revolving endless belt.
  • the traveling lid unit 2 together with the drum 1 forms the main carding zone 8 and has as function the dissolution of the flakes into single fibers, removal of impurities and dust, elimination of very short fibers, the dissolution of nits and the parallelization of the fibers.
  • This zone 8 can be defined with an angle ⁇ .
  • the zone 8 extends from the point where the first lid is placed in working position relative to the drum to the point where the last lid leaves the working position to start the return.
  • the number of lids in the working position is preferably greater than 30, so that enough Kardierlinien are available.
  • the carding drum 1 has a diameter D and a working width A (not shown in FIG. 1 ).
  • the working width A is given by the axial length of the garnished surface of the drum.
  • the working width of the drum has been increased from the usual value in the range of 1 m to 1.5 m.
  • the diameter of the drum is reduced from the usual 1.3 m to about 0.814 m. Due to the changed geometry and the corresponding changed processing parameters, the card can process more than 200 kg / h of cotton today.
  • the rotational speed of the drum can be chosen such that the peripheral speed of the drum set of the "smaller” drum is the same size as the peripheral speed of the drum set of a conventional card with a drum diameter of about 1000 mm.
  • a much higher centrifugal force is achieved at the periphery of the smaller (but wider) drum, which has an advantageous effect on the precipitation of dirt, provided that the good fibers are held securely by the drum set.
  • Each lid 7 is provided with a set, for example with a sawtooth or flexible sets in the form of prongs, whereby alternative forms of trimmings come into question.
  • the cover 7 are moved with an endless belt or a chain over pulleys 6 with a drive on the drum surface, mostly against the direction of rotation of the drum. Between the drum and the flat set is a gap called the carding nip.
  • the lids run over two flexible bows, which are arranged on each side of the drum.
  • the flexible sheet may be provided with means (not shown) for adjusting the sheets be provided so that an accurate adjustment of the carding gap can be made.
  • This carding nip is normally selected over almost the entire main carding zone so that the lids are set at a constant distance from the drum. However, the gap can also be opened - the carding gap is larger - or closing - the carding gap is smaller - to be set.
  • the size of the carding nip is, for example, between 0.10 to 0.30 mm for cotton or to 0.40 mm for chemical fibers in the case of a revolving flat card.
  • the top member 20, the suction unit 30, the carding segments 32, 36 and the separation modules 34, 38 each form a structural unit, which are attached at their ends, each having a bow 40 (only one sheet 40 in the FIG. 2 visible).
  • the sheets 40 are fastened in the card rack (not shown) by means of bolts (not shown) which cooperate with receptacles 42 on the respective sheet. Since the general structure of the group G2 is substantially the same as the general structure of the group G1, only the group G1 will be described below for the time being. Subsequently, the differences in group G2 will be briefly discussed.
  • the carding segment 32 is also in the FIG. 3 enlarged and shown in cross-section.
  • the segment 32 comprises a hollow profile 44, which serves as a holder for two carding strips 46 and 48, respectively. These strips are preferably each formed from shege leopardgarnitur Swissen, which are fastened side by side on a respective support plate 50.
  • the plates 50 are connected by means of suitable fastening means 52, only schematically indicated, releasably connected to the profile 44.
  • Each strip 46 or 48 preferably has a width B of the clothing strip (in the circumferential direction of the card) of approximately 35 mm, preferably 30 mm, for example 25 to 40 mm, advantageously 25 to 35 mm.
  • the length of the strip depends on the working width of the card, so in the case of the aforementioned C60 card, it must have a length of approx. 1500 mm. For a conventional card design, a strip length of about 1000 mm is sufficient. In the embodiment according to the FIG. 3 Each strip is firmly connected to the profile.
  • An alternative, with adjustable carding strips, is in the DE-A-10318968 and could also be used in a device according to the present application.
  • the carding element 70 is immediately adjacent to the separating gap 62.
  • the sub-profiles 54, 56 are independent of each other via their respective foot sections 66, 72, on the arch 40 ( Fig. 2 ) in each case in such a way that the distance between the foot section and the drum set can be set selectable.
  • Many fastening methods are known to those skilled in the art, which allow the required adjustability. No specific variant is shown or described here, since the selection in and of itself makes no contribution to the invention. It should be noted, however, that the elastic connection 60 must allow the mutual adjustment of the two wall parts 54, 56, while ensuring a tight connection between these parts, at their mutual points of contact.
  • FIG. 5 shows schematically (in principle) the flow conditions in the carding nip K between the carding strip 70 and the drum set with lateral surface 1A.
  • the same conditions prevail in the carding gap between the carding segment 32, 36 and the drum set.
  • the explanation of these conditions in connection with the separation module 34 is important because of the importance of the carding element 70 for the separation function.
  • the FIG. 5 shows examples of setting parameters that can be used for a carding machine with a drum diameter of 814 mm, in particular when choosing a conventional carding strip with a width B of the clothing strip of 30 mm.
  • the operating direction of rotation of the drum is indicated by a curved arrow.
  • the carding position of the clothing teeth of the carding strip is indicated schematically in that the tip of each tooth is directed against the drum rotation direction.
  • the precipitating gap 62 in Fig. 5 not indicated, cf. Fig. 4
  • the right side is the carding segment 32 (in the FIG. 5 not shown, cf. Fig. 2 ).
  • the conditions in the carding nip in the vicinity of the knife blade 64 are shown schematically in FIG FIG. 6 shown.
  • the lateral surface of the drum set is again denoted by reference numeral 1A. It is assumed that the blade 64 is attached to the foot part 66, so that the distance y between the knife edge and the lateral surface 1A is predetermined, for example in the range 0.2 to 0.6 mm, preferably approximately 0.3 to 0, 5 mm.
  • the distance between the adjacent edge region of the strip 70 and the lateral surface 1A is denoted by z and, for the reasons mentioned above, is normally slightly larger than the distance y, in the range 0.5 to 1 mm.
  • the guide surface 76 forms a curved surface which is arranged approximately concentric with the drum 1.
  • This baffle has, in particular, an effect on the air flow in the carding nip, after a part of the air quantity has been peeled off from the separating gap 62 on the blade 64 upstream and in the cavity 58 (FIG. Fig. 4 ) was discharged.
  • an increased distance between the guide surface 76 and the lateral surface 1A is preferably provided.
  • the distance between the guide surface 76 and lateral surface 1A should not be much larger than the distance y.
  • the attachment of the guide element on the foot part 66 thus preferably results in a small enlargement x of the carding gap downstream of the blade 64, for example in the range 0.15 to 0.25 mm.
  • the carding element 70 comprises a support rod 80 with a dovetail-shaped receptacle 82 for gambit pieces 82.
  • the rod 80 viewed in its longitudinal direction, extends over the entire working width of the drum and extends over its entire length provided with spacers 84, 86, wherein the two middle spacers 86 are hook-shaped and together form a receptacle for a mounting rail 88.
  • the rail 88 has distributed over its length openings 90, which are each provided with a thread. After insertion of the rod 88 into the receptacle, the apertures 90 face the apertures 92 provided in the foot portion 72.
  • each opening 92 a respective bolt 94 can be guided to match the thread of the corresponding Opening 90 to work together.
  • the rail 88 is pressed firmly against the hook-shaped spacers 86 and these are firmly clamped between the rail 88 and the foot section 72.
  • the access to the bolts 94 can be ensured via holes 96 in the wall part 56, these holes 96 are closed during operation preferably by means of a suitable cover 98.
  • As an alternative solution for fixing threaded pins can be used, which are glued into the threaded hole 90 of the rail 88 and bottom are flush ground. Since this part can be guided from below through the opening 92, only one nut has to be guided and fastened through the opening 96 for the connection.
  • a difference between the detailed construction of the elements of the groups G1 and G2 lies in the selection of the peak densities of the carding strips of the two groups.
  • the peak densities of the clothing strips in the direction of rotation of the drum are higher.
  • the peak density in group G2 is higher than the peak density in group G1.
  • the peak density of clothing strips in the group G1 is z. 160 ppsi while the peak density in group G2 may be 330 ppsi.
  • the advantageous effect of the arrangement according to the FIG. 2 is that the KardierstMail together ensure a significant pre-dissolution of the flakes before the newly introduced flakes get between the lid 7 and the Trommelgamitur. At the same time the coarsest dirt particles that are released in the implementation of this pre-resolution, as soon as possible removed from the carding nip. As a result, the trimmings of the lid 7 are relieved.
  • the division of the separation function into two separation modules allows a greater selectivity in the departure of a given amount of waste, because, for this given outflow quantity, the working elements of the separation modules 34, 38 (FIG. Fig. 2 ) can be set closer to the drum set.
  • the limited space in the Vorkardierzone are thus optimally utilized, especially if the Vorkardierzone is further restricted because of a reduction of the drum diameter.
  • the combination of carding element, blade and guide surface in a separation module can increase the selectivity without restricting the amount of waste, or with the same amount of waste, eliminating more unwanted particles and therefore less good fibers.
  • the invention relates to a device for processing fibers on the drum of a revolving flat card with a Hauptkardierzone, a Vorkardierzone and a Nachkardierzone.
  • a device for processing fibers on the drum of a revolving flat card with a Hauptkardierzone, a Vorkardierzone and a Nachkardierzone In the pre-carding zone, two groups of working elements are provided for processing fibers. Each group includes a carding segment and a separation module. Viewed in the direction of rotation of the drum, the carding segment is arranged in front of the separation module.
  • the carding segment comprises a profile attached to the carding frame with at least two carding strips.
  • the separation module comprises a profile attached to the carding frame, which forms a discharge tube which communicates with the carding gap via a separating gap.
  • the profile is provided with a knife blade after the Ausscheidespalt.
