- a drum diameter in the range 750 to 850 mm results in an improved (increased) centrifugal effect (compared to the conventional card today), with enough space is still available to the required counter elements (revolving lid, hard cover, etc.) to attach the drum. It is also possible to provide a sufficient transfer zone drum / customer.
- a working width in the range of 1300 to 1500 mm results in a sufficient production with control of the precision taking into account the high peripheral speed.
- a modern card must be provided with a sheathing, such as a sheath 201 (see schematic FIG. 5 ) according to EP-B-585196 ,
- This shell comprises a main part with two side doors 204,205 and parts 202,203 for the inlet and outlet areas. Rectangular intake openings 209,210 with bars 211 are provided in the doors and air (212, FIG. Fig. 6 ) flows through these openings in the sheathed space.
- This air should flow through suction tubes 213 and extraction supports 214 into a collection channel 215 (see also FIG Fig. 7 ) and through the card separated dirt particles and waste mitverfrachten.

- the outlet module 352 is also shown schematically in FIG Fig. 14 displayed. It includes all the working elements of the discharge section, so (except the aforementioned buyer 62) and the take-off roll 372, two non-woven conveyor rollers 374, 376, a band-forming member 378 and a tape draw 380. However, certain elements must be movably mounted on the carrier 354 to access the to ensure other elements.
- a swivel axis 373 may be provided above the pickup 62 for the take-off roll 372.
- a pivot axis 375 adjacent to the take-off roller 372 for the lower conveyor roller 376 an axis 377 provided laterally adjacent to the pickup in the sidewalls of the carrier 354, and for the units 378, 380 one axis 379, 381 below the unit itself.
- the machine frame is provided with a guide 382 for the module 352 and a guide 384 for the module 356, e.g. in the form of each pair of rails.
- Each module 352, 356 is also provided with means for cooperating with the respective guide.
- this means is provided in the form of rollers 386, wherein each carrier 354, 356 could be provided with sliding elements to cooperate with the respective guide as carriages.
- module 352 or 356 When module 352 or 356 is in place, the rollers are no longer in contact with the respective guide 382 and 384. However, the respective mechanism 368 may be actuated to pivot the carriers 354 and 358 away from the drum 50 until the rollers come into contact with the guide.

- the removal of the module 352 is not a particular problem, but the module 356 must be routed below the hopper F, or the hopper itself must be removable to allow movement of the infeed module "backwards" (against the material flow direction).
- the modules 352, 356 can therefore how to move "drawers” into or out of the standby. In this position, they can be connected to the frame or detached from it.
- Fig. 15 schematically shows the support structure for the drum 150.
- This consists of the aforementioned base plate 390 extends from side to side over the entire working width.
- a support leg pair 392 is attached (only one pair in Fig. 15 and each leg pair carries a respective end shield 394 which receives the bearings (not shown) for the drum shaft.
- Each shield 394 is also provided with protruding "ears" 396 which serve as mounting points for a revolving flat module (not shown).
- a revolving flat module is basically in EP-A-446 796 ( Fig. 12 ) and will not be explained here.
- box 300 The electronic parts of the controller and also certain power elements, such as frequency converters, can now be placed in box 300 (FIG. Fig. 11 ).
- This box can by hinges (not shown, but see Fig. 7 ) can be connected to the frame, so that the box can be pivoted away from the machine to allow access to the working elements.
- This box can form a side cover for the drum / pick / licker rolls.
- the box 300 can be provided with ribs 400 which project into the gap F1 and are thus overflowed by the air flow flowing into the suction, which causes cooling of the electronic / power parts.
- doors 402, 404 (FIG. Fig. 16 ), the air-guiding sheet-metal parts being provided on both doors 402 and 404 and having to work together with the doors closed in order to move the channels 302 (FIG. Fig. 11 ) to build. It is not a fan in this variant (cf. Fig. 7 ) provided in the machine itself. Instead, the channel 302 is provided with an extension 406 (FIG. Fig. 16 ), which adjoins the air discharge in the hopper F. Especially when using a filling shaft with cleaning point RE ( Fig. 4 ), the air systems can be combined well. It is no longer necessary to provide special air supply openings in the doors. The required air can be introduced from below.
- the cotton carding machine differs from the non-wovens card, at least in that in the outlet of the cotton carding a sliver must be formed, i. that the nonwoven fabric supplied by the rolls must be pulled together or combined over the working width (or part of the working width) to form a sliver.
- the "length" of the transfer zone between the drum and the pickup is not significantly shortened (as compared to the conventional card today).
- This "transfer zone” may be considered as the area of the drum periphery where the distance between the drum and the pickup is less than a predetermined value (e.g., 0.2 mm).
- a predetermined value e.g. 0. mm
- a reduction in the drum diameter leads to a shortening of this transfer zone, if no countermeasures are taken. For this reason, it may prove advantageous to reduce the drum diameter diameter: diameter diameter compared to conventional values today (to increase the diameter of the doffer at least relatively and at most absolutely).
- the modules 352, 356 can be inserted into their standby locations.
- the modules can be mounted outside the card on mobile maintenance equipment (eg slide), wherein for each module, first the device in a predetermined position is brought against the card and attached and then the module is moved to its working position by adjusting the device. In this case, the module is already in its ready position when fixing the device.

Ein Vliesleitelement 16 ist im Zwischenraum zwischen dem Abnehmer 7, Abnahmewalze 13 und Abzugswalzenpaar 14,15 vorgesehen. Das Leitelement 16 umfasst zumindest eine erste (Verschalungs-)Fläche 17 in der Nähe der Mantelfläche 7A und eine zweite (Vliesleit-)Fläche 18 unterhalb der Abnahmewalze 13. Die Flächen 17,18 können zusammen eine "Nase" 19 (gestrichelt angedeutet) im Zwickelspalt der Walzen bilden. Die Flächen 17,18 können auch Teil eines Hohlprofiles sein, was in
Die Arbeitsbreite B der Trommel 4 ist für alle anderen Arbeitselemente der Karde massgebend, insbesondere für
- die Wanderdeckel, (oder Festdeckel in einer Festdeckelkarde), welche zusammen mit der Trommel die Fasern gleichmässig über die ganze Arbeitsbreite B kardieren müssen,
- das Zuführsystem, welches stets einen gleichmässig verteilten Faserstrom an
die Trommel 4 über die ganze Arbeitsbreite B gewährleisten muss, und - das Abnahmesystem, welches stets gleichmässig Fasern
von der Trommel 4 über die ganze Arbeitsbreite B abheben soll.
- the revolving lids, (or hard covers in a hard-cover card), which together with the drum must card the fibers uniformly over the entire working width B,
- the feeding system, which must always ensure a uniformly distributed fiber flow to the
drum 4 over the entire working width B, and - the removal system, which is always uniform fibers from the
drum 4 over the entire working width B should stand out.

Noch wichtiger ist die Arbeitsbreite. Eine Karde nach
Im allgemeinen ist es vorteilhaft, eine "kleine" (kleintambourige) Karde mit einer etwas höheren Umfangsgeschwindigkeit anzutreiben, als zur Verarbeitung des gleichen Fasersortimentes bei der gleichen Produktion in einer konventionellen Karde verwendet wird. Das Antriebssystem (nicht gezeigt) muss entsprechend ausgelegt werden. Die Umfangsgeschwindigkeit einer (heute) konventionellen Karde (im Normalbetrieb) liegt im Bereich 20 bis 40 m/s, was einer Drehzahl von 300 bis 600 U/min entspricht. Um diese Umfangsgeschwindigkeit in der neuen (kleineren) Karde aufrechtzuerhalten, muss die Trommel mit einer Drehzahl im Bereich 500 bis 1000 U/min angetrieben werden. Vorzugsweise ist die Trommel dazu ausgelegt, mit einer noch höheren Drehzahl angetrieben zu werden, ohne Festigkeits-, Steifigkeits- oder Schwingungsprobleme aufzuwerfen.In general, it is advantageous to drive a "small" (small-chip) card at a slightly higher peripheral speed than to process the same Fiber assortment used in the same production in a conventional carding machine. The drive system (not shown) must be designed accordingly. The peripheral speed of a (today) conventional card (in normal operation) is in the range 20 to 40 m / s, which corresponds to a speed of 300 to 600 rpm. In order to maintain this peripheral speed in the new (smaller) card, the drum must be driven at a speed in the range of 500 to 1000 rpm. Preferably, the drum is designed to be driven at an even higher speed without posing strength, stiffness or vibration problems.

Ein Winkel α von maximal 90°, vorzugsweise 60 - 75° reicht für den genannten Zweck.An angle α of at most 90 °, preferably 60-75 ° is sufficient for the stated purpose.
Das Verhältnis vom Durchmesser D der Trommel 150 zum Durchmesser d des Abnehmers 62 ist auch ein wichtiges Merkmal der bevorzugten Ausführung der Karde nach
Die Lösung nach
Das Wanderdeckelaggregat 152 in
Ein Trommeldurchmesser im Bereich 750 bis 850 mm (z.B. 810 bis 820 mm) ergibt eine verbesserte (erhöhte) Fliehkraftwirkung (verglichen mit der heute konventionellen Karde), wobei noch genügend Platz vorhanden ist, um die erforderlichen Gegenelemente (Wanderdeckel, Festdeckel usw.) an der Trommel anzubringen. Es ist auch möglich eine ausreichende Übergabezone Trommel/Abnehmer vorzusehen. Eine Arbeitsbreite im Bereich 1300 bis 1500 mm ergibt eine ausreichende Produktion bei Beherrschung der Präzision unter Berücksichtigung der hohen Umfangsgeschwindigkeit.A drum diameter in the range 750 to 850 mm (eg 810 to 820 mm) results in an improved (increased) centrifugal effect (compared to the conventional card today), with enough space is still available to the required counter elements (revolving lid, hard cover, etc.) to attach the drum. It is also possible to provide a sufficient transfer zone drum / customer. A working width in the range of 1300 to 1500 mm results in a sufficient production with control of the precision taking into account the high peripheral speed.
Eine moderne Karde muss mit einer Ummantelung versehen werden, beispielsweise einer Ummantelung 201 (siehe schematische

Das Verstellen eines Moduls 352 bzw. 356 um die jeweilige Schwenkachse 364, 366 wird durch die Hebelwirkung zwischen der Achse und einer jeweiligen von der Schwenkachse entferntem Einstellort 365, 367 bewerkstelligt. An jedem Einstellort 365, 367 befindet sich ein Verstellmechanismus, der in
Das Einlaufmodul 356 umfasst alle drei Vorreisser 58, 58A und 58B sowie die Speisewalze 56 samt ihrer zugeordneten Mulde und Motoren für die Vorreisser und Speisewalze. Die Walzen 58A, 58B und 56 können linear in der Längsrichtung des Moduls verschoben werden, um den jeweiligen Arbeitsspalt bis zur nächsten Walze in der Reihe einzustellen. Das Auslaufmodul 352 ist auch schematisch in
Die dargestellten Schwenkbewegungen lassen den Zugang für kleinere Arbeiten, insbesondere für das Putzen der Elemente, zu. Für umfangreichere Wartungsarbeiten wird es aber erforderlich sein, das jeweilige Modul als ganzes aus der Maschine zu entnehmen. Zu diesem Zweck ist das Maschinengestell mit einer Führung 382 für das Modul 352 und einer Führung 384 für das Modul 356 versehen, z.B. in der Form je eines Schienenpaares. Jedes Modul 352, 356 ist auch mit Mitteln zum Zusammenarbeiten mit der jeweiligen Führung versehen. In der schematischen Abbildung ist dieses Mittel in der Form von Rollen 386 vorgesehen, wobei jeder Träger 354, 356 mit Gleitelementen versehen werden könnte, um mit der jeweiligen Führung als Schlitten zusammenzuarbeiten.The illustrated pivoting movements allow access for smaller jobs, especially for cleaning the elements. For more extensive maintenance, however, it will be necessary to remove the respective module as a whole from the machine. For this purpose, the machine frame is provided with a
Wenn das Modul 352 bzw. 356 in seiner Arbeitsstelle ist, stehen die Rollen bzw. Gleitmittel nicht mehr in Berührung mit der jeweiligen Führung 382 und 384. Der jeweilige Mechanismus 368 kann aber betätigt werden, um die Träger 354 und 358 von der Trommel 50 wegschwenken zu lassen, bis die Rollen in Berührung mit der Führung treten. Die Führung ist idealerweise im Maschinenunterbau integriert. Das Modul 352 bzw. 356 steht dann in seiner Bereitschaftsposition. Aus dieser Position kann es in der Längsrichtung der Maschine der jeweiligen Führung 382, 384 entlang bewegt werden, wenn die Verbindung an der jeweiligen Schwenkachse 364, 366 gelockert wird. Das Herausnehmen des Moduls 352 stellt kein besonderes Problem dar, das Modul 356 muss aber unterhalb des Füllschachtes F geführt werden, oder der Schacht selbst muss entfernt werden können, um die Bewegung des Einlaufmoduls "nach hinten" (gegen die Materialflussrichtung) zu ermöglichen. Die Module 352, 356 können daher wie "Schubladen" in die bzw. aus der Bereitschaftsstelle verschoben werden. In dieser Stelle können sie mit dem Gestell verbunden bzw. davon gelöst werden.When

Wenn die Karde nun "geöffnet" wird (die Türen 402, 404 geöffnet und der Kasten 300 weggeschwenkt), kommen die Bedienungspersonen nun direkt an die einzustellenden Elemente wie z.B. Trommelverschalungselemente, "Zunge" (vgl.
Wie schon erwähnt, ist es möglich die Erfindung auch in Maschinen zur Herstellung von Non-Wovens einzusetzen. Die bevorzugte Anwendung ist aber in der "Baumwoll-karde " (Stapelfaserspinnerei). Die Baumwollkarde unterscheidet sich von der Non-Wovens-Karde zumindest darin, dass im Auslauf der Baumwollkarde ein Faserband gebildet werden muss, d.h. dass das von den Walzen gelieferte Vlies über die Arbeitsbreite (bzw. einen Teil der Arbeitsbreite) zu einem Faserband zusammengezogen bzw. zusammengefasst werden muss.As already mentioned, it is possible to use the invention in machines for the production of non-wovens. The preferred application is in the "cotton-karde" (staple fiber spinning). The cotton carding machine differs from the non-wovens card, at least in that in the outlet of the cotton carding a sliver must be formed, i. that the nonwoven fabric supplied by the rolls must be pulled together or combined over the working width (or part of the working width) to form a sliver.
In der bevorzugten Anordnung wird die "Länge" der Übergabezone zwischen der Trommel und dem Abnehmer nicht wesentlich verkürzt (im Vergleich mit der heute konventionellen Karde). Diese "Übergabezone" kann als die Zone des Trommelumfanges betrachtet werden, wo der Abstand zwischen der Trommel und dem Abnehmer kleiner als ein vorbestimmter Wert (z.B. 0,2 mm) ist. Eine Reduktion im Trommeldurchmesser führt zu einer Verkürzung dieser Übergabezone, wenn keine Gegenmassnahmen getroffen werden. Deshalb kann es sich als vorteilhaft erweisen, das Verhältnis Trommeldurchmesser: Abnehmerdurchmesser gegenüber den heute konventionellen Werten zu verkleinern (der Abnehmerdurchmesser zumindest relativ und allenfalls absolut zu vergrössern).In the preferred arrangement, the "length" of the transfer zone between the drum and the pickup is not significantly shortened (as compared to the conventional card today). This "transfer zone" may be considered as the area of the drum periphery where the distance between the drum and the pickup is less than a predetermined value (e.g., 0.2 mm). A reduction in the drum diameter leads to a shortening of this transfer zone, if no countermeasures are taken. For this reason, it may prove advantageous to reduce the drum diameter diameter: diameter diameter compared to conventional values today (to increase the diameter of the doffer at least relatively and at most absolutely).
