Description

Die Erfindung richtet sich auf eine Garnitur für Kämm­walzen, insbesondere für Woll- und Baumwollkämm-Ma­schinen, umfassend eine Mehrzahl in Form von Riegeln axial nebeneinander angeordneten Sägezahnstanzteile.The invention is directed to a set for combing rollers, in particular for wool and cotton combing machines, comprising a plurality of sawtooth stampings arranged axially next to one another in the form of bars.

Kämmwalzen werden entweder mit Nadeln oder alternativ hierzu in neuerer Zeit bevorzugt mit Sägezahndrähten oder -stanzteilen garniert.Combing rollers are garnished either with needles or, alternatively, more recently with sawtooth wires or punched parts.

Bei den früher vor allem üblichen Nadelgarnituren wur­den die losen Nadeln auf sogenannte Barrette aufgelö­tet. Die Nadeln wurden in sogenannte Setzgravuren ge­setzt, Spitze auf Spitze angeglichen und dann mit Löt­zinn an den Barretten befestigt. Die Nadeln jedes Bar­rettes wurden auf eine bestimmte Dichte gesetzt. Unter Dichte ist dabei der Abstand in Längsrichtung zwischen den Nadelspitzen zu verstehen. Im allgemeinen wurde die erste Nadelreihe mit vier Nadeln pro cm gesetzt, d.h. der axiale Abstand der Nadelspitzen zueinander betrug 2,5 mm. Bei dem in Kämmrichtung gesehen zweiten Barrett wurden die Nadeln in Längsrichtung mit sechs Nadeln pro cm angeordnet. Der Spitzenabstand der Na­deln verringerte sich dementsprechend von Barrett zu Barrett. So wurden z.B. in der letzten Nadelreihe die Nadeln schon mit einer Dichte von 32 Nadeln pro cm ge­setzt. Durch diese Anordnung erreichte man ein scho­nendes Kämmen der Woll- bzw. Baumwollfasern. Auch wur­de durch diese Technik erreicht, daß das Faservlies von den Unreinheiten gereinigt wurde.In the case of the needle sets that used to be common in the past, the loose needles were soldered onto so-called barrettes. The needles were set in so-called engravings, matched tip to tip and then attached to the barrels with solder. The needles of each Barrette were set to a certain density. The density is the distance in the longitudinal direction between to understand the needle tips. In general, the first row of needles was set with four needles per cm, ie the axial distance between the needle tips was 2.5 mm. In the second Barrett seen in the combing direction, the needles were arranged in the longitudinal direction with six needles per cm. The tip spacing of the needles decreased accordingly from Barrett to Barrett. In the last row of needles, for example, the needles were already set with a density of 32 needles per cm. With this arrangement, gentle combing of the wool or cotton fibers was achieved. It was also achieved by this technique that the fiber fleece was cleaned of the impurities.

Mit einer Verbesserung der Kämm-Maschinen in Bezug auf das Kämmspiel pro Minute sowie mit der Erhöhung der Vorlage des Kämmgutes wurden die anfälligen Nadelspit­zen zu sehr belastet, so daß man mehr und mehr zu Sägezahngarnituren überging. Diese Garnierungen wurden in der Regel aus einem endlosen sogenannten Kratzen­draht hergestellt. Die einzelnen Zähne auf diesem Kratzendraht waren herstellungsbedingt untereinander identisch ausgebildet. Von diesem Kratzendraht wurden bestimmte Längen abgeschnitten und mit einem der Kämm­walze entsprechenden Radius gebogen und längs neben­einander auf die Kämmwalzen aufgebracht. Der Spitzen­abstand in Längsrichtung, d.h. in Richtung parallel zur Drehachse der Kämmwalze, wurde dabei bestimmt durch die Dicke des verwendeten Kratzendrahtes. Diese Garnierungsart brachte gegenüber der Nadelgarnierung den Vorteil, daß die Standzeit wesentlich erhöht wur­de. Der Nachteil einer derartigen Garnierung besteht jedoch darin, daß von der ersten Spitzenreihe bis zu der letzten Spitzenreihe der Spitzenabstand radial gleich war, so daß in Kauf genommen werden mußte, daß das Eindringen der ersten Spitzenreihe nicht schonend genug erfolgte, weil man den axialen Spitzenabstand in seiner Dichte so gestalten mußte, daß in jedem Fall noch eine gute Auskämmung erreicht wurde. Dies führt zu Faserrissen und einer nicht optimalen Auskämmung des Faserbartes.With an improvement in the combing machines in terms of combing play per minute and with an increase in the amount of combed material, the susceptible needle tips became too stressed, so that more and more sawtooth sets were used. These trimmings were usually made from an endless so-called scratch wire. The individual teeth on this scratch wire were identical to one another due to the manufacturing process. Certain lengths were cut from this scraping wire and bent with a radius corresponding to the combing roller and applied lengthwise alongside one another to the combing rollers. The tip spacing in the longitudinal direction, ie in the direction parallel to the axis of rotation of the combing roller, was determined by the thickness of the scraping wire used. This type of garnishing had the advantage over needle garnishing that the service life was increased considerably. The disadvantage of such a garnish is however, in that from the first row of tips to the last row of tips, the tip spacing was radially the same, so that it had to be accepted that the penetration of the first row of tips was not gentle enough because the density of the axial tip spacing had to be designed in this way, that in any case a good combing was achieved. This leads to fiber tears and not optimal combing of the fiber beard.

Um hier eine Verbesserung zu erreichen ist es auch schon bekannt, die Garnierung in Teilsegmente aufzu­teilen, wobei der Spitzenabstand in Längsrichtung des Riegels sich von Teilsegment zu Teilsegment gegen die Kämmrichtung nach hinten verminderte. Allerdings wurde hierdurch nicht die Spitzendichte von Nadelgarnituren mit vier Nadeln pro cm erreicht, weil der Kratzendraht nicht hinreichend dünn hergestellt werden konnte.In order to achieve an improvement here, it is also known to divide the garnish into sub-segments, with the tip spacing in the longitudinal direction of the bar decreasing from the sub-segment to the sub-segment towards the rear in the combing direction. However, this did not achieve the peak density of needle sets with four needles per cm because the scratch wire could not be made sufficiently thin.

Aus dem DE-GM 84 3o 562 ist eine gattungsgemäße Garni­tur bekannt, bei welcher die Sägezahngarnitur durch einzelne Sägezahnstanzteile gebildet wird, welche in Form von Riegeln nebeneinander angeordnet und zusam­mengefaßt sind. Zur Verbesserung des Eindringverhal­tens der Zähne dieser Sägezahnstanzteile in den Faser­bart ist es aus dieser Druckschrift schon bekannt, die einzelnen Zähne eines Stanzteiles untereinander derart unterschiedlich auszubilden, daß die Spitzenhöhe, der Spitzenabstand innerhalb des Stanzteils und der Flan­keneingriffswinkel gegen die Kämmrichtung gesehen ab­nehmen. Hierdurch konnte schon eine wesentliche Ver­besserung des Eingriffsverhaltens erzielt werden, jedoch ist es noch nicht gelungen, in optimaler Weise die hohen Standzeiten derartiger Garnituren mit dem von Nadelgarnituren bekannten vorteilhaften Eingriffs­verhalten zu vereinbaren.From DE-GM 84 3o 562 a generic set is known, in which the sawtooth set is formed by individual sawtooth punched parts, which are arranged next to one another and combined in the form of bars. In order to improve the penetration behavior of the teeth of these sawtooth punched parts into the fiber beard, it is already known from this publication to design the individual teeth of a punched part differently from one another in such a way that the tip height, the tip spacing within the punched part and the flank pressure angle decrease in relation to the combing direction. This has already achieved a significant improvement in the intervention behavior, However, it has not yet been possible to optimally reconcile the long service lives of such sets with the advantageous engagement behavior known from needle sets.

Hiervon ausgehend liegt der Erfindung die Aufgabe zu­grunde, eine Garnitur der eingangs genannten Art so auszugestalten, daß ein möglichst verbessertes Ein­griffsverhalten der Garnitur in den Faserbart bei hoher Kämmqualität erreicht wird.Proceeding from this, the object of the invention is to design a clothing of the type mentioned at the outset in such a way that the behavior of the clothing in the fiber beard is improved as much as possible with a high quality of combing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß innerhalb eines Riegels Sägezahnstanzteile mit einer unterschiedlichen Zahl von Spitzen pro Stanzteil ange­ordnet sind. Dies ermöglicht es, die Spitzendichte von der in Kämmrichtung gesehen vordersten Spitzenreihe nach hinten zu erhöhen, so daß auf diese Weise ein sanfter und schonender Eingriff unter Vermeidung von Faserrissen mit einer zur Erzielung einer hervorragen­den Kämmwirkung ausreichenden Spitzendichte kombinier­bar ist.This object is achieved in that saw tooth punched parts are arranged with a different number of tips per stamped part within a bar. This makes it possible to increase the tip density from the front row of tips as seen in the combing direction, so that in this way a gentle and gentle intervention while avoiding fiber tears can be combined with a tip density sufficient to achieve an excellent combing effect.

Dies wird vorteilhafterweise so realisiert, daß die Stanzteile eines Riegels die gleiche Grundgeometrie aufweisen, wobei ausgehend von dem in Kämmrichtung gesehen vorderen Ende eine unterschiedliche Zahl von Zähnen vorgesehen ist. Mit anderen Worten wird also die vorgesehene unterschiedliche Anzahl von Zähnen nicht etwa dadurch realisiert, daß man die Zähne über die Länge jedes Stanzteils gleichmäßig verteilt, son­dern daß man eine gewisse Anzahl der vorne liegenden Zähne wegläßt, so daß lediglich das glatte, durchge­hende Fußteil in diesem Bereich verbleibt.This is advantageously realized in such a way that the stamped parts of a bolt have the same basic geometry, with a different number of teeth being provided starting from the front end viewed in the combing direction. In other words, the envisaged different number of teeth is not realized by distributing the teeth evenly over the length of each stamped part, but by a certain number of the front ones Leaves teeth so that only the smooth, continuous foot part remains in this area.

Vorteilhafterweise ist vorgesehen, daß sich die Spit­zenverteilung innerhalb eines Riegels nach jeweils m Stanzteilen periodisch wiederholt. Dies bedeutet, daß die jeweils vordersten Spitzen zusammen mit den nach­folgenden eine gleichmäßige, z.B. V-förmige, periodi­sche Struktur ausbilden.It is advantageously provided that the peak distribution within a bar is repeated periodically after every m stamped parts. This means that the foremost tips together with the following tips have an even, e.g. Form a V-shaped, periodic structure.

Insbesondere kann vorgesehen sein, daß innerhalb einer Periode benachbart zu einem Stanzteil mit einer Maxi­malzahl von n Zähnen jeweils Sägezahnstanzteile mit n-1, benachbart zu diesen Sägezahnstanzteile mit n-2 Zähnen usw. angeordnet sind. Hierdurch wird erreicht, daß die Spitzendichte von den in Kämmrichtung gesehen vorne liegenden Zahnreihen nach hinten zunimmt. Dabei kann natürlich der Unterschied in der Zahnzahl benach­barter Stanzteile auch größer als 1 sein oder aber von vorne nach hinten sich progressiv ändern.In particular, it can be provided that saw tooth punched parts with n-1, adjacent to these saw tooth punched parts with n-2 teeth, etc. are arranged within a period adjacent to a punched part with a maximum number of n teeth. It is hereby achieved that the tip density increases from the rows of teeth lying at the front in the combing direction to the rear. Of course, the difference in the number of teeth of adjacent stamped parts can also be greater than 1 or change progressively from front to back.

Günstigerweise können an sich bekannte Distanzscheiben zwischen den einzelnen Sägezahnstanzteilen angeordnet werden, um auf diese Weise einen an eine spezifische Kämmaufgabe angepaßten Spitzenabstand einzustellen.Advantageously, known spacer disks can be arranged between the individual sawtooth punched parts in order in this way to set a tip distance adapted to a specific combing task.

Die vorstehend angesprochene Grundgeometrie jedes ein­zelnen Sägezahnstanzteiles ist in an sich bekannter Weise mit Vorteil so ausgestaltet, daß die Spitzen­höhe, der Spitzenabstand und der Flankeneingriffswin­kel der Zähne dieses Stanzteils in Kämmrichtung ge­sehen nach hinten abnimmt. Die Verbindung dieser für sich gesehen sehr günstigen Grundgeometrie mit einer erfindungsgemäßen Anordnung bringt besonders heraus­ragende Kämmergebnisse.The above-mentioned basic geometry of each individual sawtooth stamped part is advantageously designed in a manner known per se such that the tip height, the tip spacing and the flank pressure angle of the teeth of this stamped part decrease in the combing direction as seen to the rear. The connection of these for seen very favorable basic geometry with an arrangement according to the invention brings particularly excellent combing results.

Die in Fig. 1 dargestellten Sägezahnstanzteile 1 wei­sen sämtliche die gleiche Grundform auf, d.h. sie sind mit einem Fußteil 2 und einer Mehrzahl von Zähnen 3 versehen, wobei die Zähne 3 so ausgebildet sind, daß in Kämmrichtung gesehen (Pfeil 4) die Zähne am vorde­ren Ende 5 des Stanzteils 1 eine größere Spitzenhöhe H sowie einen größeren Spitzenabstand D aufweisen.The sawtooth stamped parts 1 shown in FIG. 1 all have the same basic shape, ie they are provided with a foot part 2 and a plurality of teeth 3, the teeth 3 being designed such that, when viewed in the combing direction (arrow 4), the teeth at the front end 5 of the stamped part 1 have a larger tip height H and a larger tip distance D.

Dementsprechend unterscheiden sich die verschiedenen Stanzteile 1 lediglich dadurch, daß durch Weglassung des jeweils vordersten Zahns 3 ausgehend von dem Stanzteil 1A mit n Zähnen das Stanzteil 1B n-1, das Stanzteil 1C n-2, das Stanzteil 1D n-3 und das Stanz­teil 1E n-4 Zähne aufweist.Accordingly, the different stamped parts 1 differ only in that, by omitting the foremost tooth 3 starting from the stamped part 1A with n teeth, the stamped part 1B n-1, the stamped part 1C n-2, the stamped part 1D n-3 and the stamped part 1E has n-4 teeth.

Im Ausführungsbeispiel sind diese fünf unterschiedli­che Stanzteile zu einem in Fig. 3 ausschnittsweise dargestellten Riegel 6 parallel zur Drehachse der zu garnierenden Kämmwalze nebeneinander so aufgezogen, daß ausgehend von einem Stanzteil 1A mit maximaler Zahnzahl Stanzteile 1 mit jeweils abnehmender Zahnzahl folgen, bis das Stanzteil 1E mit minimaler Zahnzahl erreicht ist, wobei anschließend wieder ein Stanzteil mit einem Zahn mehr usw. aufgereiht wird, bis wieder ein Stanzteil 1A mit maximaler Zahnzahl erreicht ist. Auf diese Weise ergibt sich eine periodische Wieder­holung nach jedem m-ten Stanzteil, wobei im Ausfüh­rungsbeispiel m=8 ist.In the exemplary embodiment, these five different stamped parts are drawn up side by side to form a bar 6, shown in detail in FIG. 3, parallel to the axis of rotation of the combing roller to be garnished, so that, starting from a stamped part 1A with a maximum number of teeth, stamped parts 1 with a decreasing number of teeth follow until the stamped part 1E with minimum number of teeth is reached, with a stamped part with one more tooth etc. then being lined up until a stamped part 1A with a maximum number of teeth is reached again. In this way, there is a periodic repetition after every m-th stamped part, m = 8 in the exemplary embodiment.

In Fig. 6 ist die sich aus einer solchen Aneinander­reihung ergebende Spitzenverteilung deutlich erkenn­bar. Dabei weist ein in Fig. 2 im Querschnitt darge­stelltes Stanzteil 1 eine Breite S auf. In der ersten Spitzenreihe (erste Sp.) weisen zwei in einer Reihe benachbarte Zähne 3 einen Abstand von Sx16, in der zweiten Reihe (zweite Sp.) einen Abstand von Sx8, in der dritten Reihe (dritte Sp.) einen Abstand von Sx4, in der vierten Reihe (vierte Sp.) einen Abstand von Sx2 und in der fünften Reihe (fünfte Sp.) sowie in allen folgenden Reihen einen Abstand S entsprechend der Breite eines Stanzteils 1 auf. Hierdurch entsteht eine Konfiguration, bei welcher am vorderen Ende 5 des Riegels 6 zunächst einzelne Zähne 3 V-förmig vorsprin­gen, wobei weiter nach hinten die Spitzendichte zu­nimmt. Auf diese Weise ist ein schonendes Eintauchen der Garnierung der vorzugsweise auf Kreiskammsegmenten angebrachten Riegel in den Faserbart zu erreichen. Der Prozenzsatz des Kämmlings wird durch diese schonende Kämmen, wie Versuche zeigen, wesentlich herangesetzt. Vor allem aber ist wichtig, daß durch diese Ausgestal­tung die nachfolgenden Kammsegmente wieder feiner aus­gestaltet werden können, so daß damit eine effekti­vere, saubere Kämmung des Faserbarts möglich ist.6 shows the peak distribution resulting from such a sequence. A stamped part 1 shown in cross section in FIG. 2 has a width S. In the first row of laces (first column) there are two in a row adjacent teeth 3 a distance of Sx16, in the second row (second column) a distance of Sx8, in the third row (third column) a distance of Sx4, in the fourth row (fourth column) a distance of Sx2 and in the fifth row (fifth column) and in all subsequent rows there is a distance S corresponding to the width of a stamped part 1. This creates a configuration in which, at the front end 5 of the latch 6, individual teeth 3 initially project in a V-shape, the tip density increasing further to the rear. In this way, a gentle immersion of the garnish of the bars, which are preferably attached to circular comb segments, can be achieved in the fiber beard. The percentage rate of combing is significantly increased by this gentle combing, as tests show. Above all, however, it is important that the following comb segments can be made finer again by this configuration, so that a more effective, clean combing of the beard is possible.

Bei der in Fig. 7 dargestellten Ausführungsform ist der grundsätzliche Aufbau ähnlich, jedoch sind dort Distanzscheiben 7 mit einer Querschnittsbreite S¹, wie in Fig. 5 dargestellt, zwischen die einzelnen Säge­zahnstanzteile 1 eingesetzt.In the embodiment shown in FIG. 7, the basic structure is similar, but there are spacers 7 with a cross-sectional width S 1, as shown in FIG. 5, inserted between the individual saw tooth punched parts 1.

Für die Sägezahnstanzteile 1 wird z.B. eine Quer­schnittsbreite von o,3 mm ermöglicht. Dieses Maß wird je nach dem Einsatz für Wolle oder Baumwolle dimensio­niert, wobei durch die Distanzscheiben noch weitere Variationen möglich sind.For the sawtooth stamped parts 1, e.g. enables a cross-sectional width of 0.3 mm. This dimension is dimensioned depending on the use for wool or cotton, whereby further variations are possible due to the spacers.
