Description

Die Erfindung bezieht sich auf ein Rundkammsegment zur Befestigung auf einer Rundkammwalze einer Kämmaschine, mit einem Grundkörper, der eine sich zylindersegmentförmig von einem vorderen Rand zu einem hinteren Rand erstreckende, mit Kämmnadeln oder Kämmgarnituren besetzte äussere Umfangsfläche aufweist.The invention relates to a circular comb segment for attachment to a circular comb roller of a combing machine, with a base body which has an outer peripheral surface which is in the form of a cylindrical segment and extends from a front edge to a rear edge and is equipped with combing needles or combing sets.

Eine derartige Kämmaschine ist aus dem Dokument FR-A-2449144 bekannt.Such a combing machine is known from document FR-A-2449144.

Rotierende Rundkämme mit solchen Rundkammsegmenten werden in Kämmaschinen üblicherweise verwendet. Ein Zangenaggregat hält dem Rundkammsegment bei jedem Umlauf desselben jeweils einen Faserbart zum Auskämmen vor. In modernen Kämmaschinen kann der Rundkamm mit bis zu etwa 300 U/min drehen und kann die zu kämmende Watte dem Zangenaggregat mit einer mittleren Geschwindigkeit von bis zu beinahe 2 m/min und mit einem Gewicht von bis zu etwa 230 g/m² zugeführt werden, d.h. bis zu etwa 4,5 g Watte pro Minute und pro cm Breite des Rundkamms. Wenn man die Produktion durch Erhöhen der Geschwindigkeit und/oder Erhöhen des Wattegewichtes weiter steigern will, muss man feststellen, dass der dem Rundkammsegment vorgehaltene Faserbart nicht mehr einwandfrei und vollständig durchgekämmt wird.Rotating round combs with such round comb segments are usually used in combing machines. A pair of pliers holds a fiber beard for combing out the round comb segment each time it rotates. In modern combing machines, the circular comb can rotate at up to about 300 rpm and the cotton to be combed can be fed to the pliers unit at an average speed of up to almost 2 m / min and with a weight of up to about 230 g / m², ie up to about 4.5 g of cotton per minute and per cm of width of the round comb. If you want to increase production further by increasing the speed and / or increasing the cotton weight, you have to determine that the fiber beard held in front of the circular comb segment is no longer combed perfectly and completely.

Die Aufgabe der Erfindung besteht darin, ein Rundkammsegment der eingangs angegebenen Art derart auszubilden, dass auch bei gesteigerter Produktion, d.h. erhöhter Geschwindigkeit und/oder erhöhtem Wattegewicht, der Faserbart vollständig und einwandfrei durchgekämmt wird.The object of the invention is to design a circular comb segment of the type specified at the outset in such a way that even with increased production, i.e. increased speed and / or increased cotton weight, the fiber beard is combed completely and properly.

Die bekannten und heute üblichen Rundkammsegmente der angegebenen Art besitzen einen Grundkörper, in der Regel einen gezogenen Grundkörper, an den vor dem vorderen Rand und hinter dem hinteren Rand der äusseren Umfangsfläche je eine abstehende Leiste mit Bohrungen angeformt ist, welche Schrauben aufnehmen, die in eine Rundkammwalze geschraubt werden, um das Rundkammsegment an der Walze zu befestigen.The known round comb segments of the specified type, which are common today, have a base body, generally a drawn base body, on each of which a protruding ledge with bores is formed on the front edge and behind the rear edge of the outer circumferential surface, which take up screws, which are screwed into a circular comb roller in order to fix the circular comb segment to the roller.

Es ist nun gefunden worden, dass bei den bekannten Rundkammsegmenten die vordere Befestigungsleiste des Grundkörpers, die über den vorderen Rand der äusseren Umfangsfläche und damit auch über die vordersten Kämmnadeln bzw. Kämmgarniturspitzen hinaus nach vorn vorsteht, die Erhöhung der Produktion verhindert. Die vordere Befestigungsleiste tritt mit den Fasern des dem Rundkammsegment vorgehaltenen Faserbartes in Berührung, bevor diese von den vordersten Kämmnadeln bzw. Garniturspitzen erfasst werden. Wenn man nun die Geschwindigkeit und/oder das Wattegewicht erhöht, dann kann die vordere Befestigungsleiste einige der Fasern des Faserbartes so weit radial wegstossen oder wegschleudern, dass der Faserbart von den Kämmnadeln bzw. Garniturspitzen nicht mehr vollständig durchstochen und in das Rundkammsegment gezogen wird.It has now been found that, in the known circular comb segments, the front fastening strip of the base body, which protrudes forward over the front edge of the outer peripheral surface and thus also over the foremost combing needles or combing tips, prevents the increase in production. The front fastening strip comes into contact with the fibers of the fiber beard held up to the circular comb segment before they are gripped by the foremost combing needles or clothing tips. If you now increase the speed and / or the cotton weight, the front fastening strip can push or fling away some of the fibers of the fiber beard so far that the fiber beard is no longer completely pierced by the combing needles or clothing tips and is pulled into the round comb segment.

Das erfindungsgemässe Rundkammsegment, mit dem die gestellte Aufgabe gelöst wird, ist daher dadurch gekennzeichnet, dass in Umfangsrichtung vor einer Ebene, die durch die Achse der Zylindersegmentform und durch den vorderen Rand geht, ein freier Raum vorhanden ist, der sich in radialer Richtung vom vorderen Rand aus zumindest über den grössten Teil der Dicke des Grundkörpers erstreckt und in Richtung der Breite des Grundkörpers von der Mitte des vorderen Randes aus nach beiden Seiten über zumindest den grössten Teil der Breite des Grundkörpers erstreckt.The circular comb segment according to the invention, with which the object is achieved, is therefore characterized in that in the circumferential direction in front of a plane which passes through the axis of the cylindrical segment shape and through the front edge, there is a free space which extends in the radial direction from the front Edge extends at least over most of the thickness of the base body and extends in the direction of the width of the base body from the center of the front edge to both sides over at least most of the width of the base body.

Die bisher übliche, durchgehende vordere Befestigungsleiste am Grundkörper soll also wegfallen. Der Grundkörper muss daher im Bereich seines vorderen Randes anders als bisher üblich auf der Rundkammwalze befestigt werden. Dafür gibt es verschiedene Möglichkeiten, von denen einige der nachstehenden Beschreibung von Ausführungsbeispielen der Erfindung anhand der Zeichnungen entnommen werden können. Bei den bevorzugten Befestigungsarten erstreckt sich der freie Raum vor der genannten Ebene über die ganze Dicke und/oder über die ganze Breite des Grundkörpers.The previously common, continuous front fastening strip on the base body should therefore be eliminated. The base body must therefore be attached to the round comb roller in the area of its front edge in a manner different from what has been customary up to now. There are various possibilities for this, some of which can be found in the following description of exemplary embodiments of the invention with reference to the drawings. In the preferred types of attachment, the free one extends Space in front of said level over the entire thickness and / or over the entire width of the base body.

In den Draufsichten der Fig. 2, 4, 6, 8, 10 und 12 ist jeweils nur eine Hälfte des Rundkammsegmentes dargestellt, die andere Hälfte ist zu der dargestellten Hälfte symmetrisch.In the top views of FIGS. 2, 4, 6, 8, 10 and 12 only one half of the circular comb segment is shown, the other half is symmetrical to the half shown.

Jedes der dargestellten Rundkammsegmente besitzt jeweils einen Grundkörper 1 mit einer äusseren Umfangsfläche 2, die sich zylindersegmentförmig von einem vorderen Rand 3 bis zu einem hinteren Rand 4 erstreckt. Die äussere Umfangsfläche 2 ist mit Kämmnadeln oder Kämmgarnituren 5 besetzt. In den Fig. 1, 3, 5, 7, 9 und 11 ist jeweils mit einer unterbrochenen Linie eine Ebene E eingezeichnet, die durch den vorderen Rand 3 der äusseren Umfangsfläche 2 und durch die Achse der Zylindersegmentform dieser äusseren Umfangsfläche geht.Each of the circular comb segments shown has a base body 1 with an outer circumferential surface 2, which extends in the form of a cylinder segment from a front edge 3 to a rear edge 4. The outer peripheral surface 2 is equipped with combing needles or combing sets 5. 1, 3, 5, 7, 9 and 11, a plane E is drawn with a broken line, which goes through the front edge 3 of the outer peripheral surface 2 and through the axis of the cylindrical segment shape of this outer peripheral surface.

Die Rundkammsegmente werden jeweils auf einer ebenfalls mit einer unterbrochenen Linie angedeuteten Rundkammwalze R einer Kämmaschine befestigt, und zwar mit Schrauben (nicht dargestellt), die in Gewindebohrungen in der Rundkammwalze R geschraubt werden.The round comb segments are each on one also attached with a broken line circular comb roller R of a combing machine, with screws (not shown) which are screwed into threaded holes in the circular comb roller R.

Bei dem bekannten Rundkammsegment, das in den Fig. 1 und 2 dargestellt ist, ist an den Grundkörper 1 vor dem vorderen Rand 3 und hinter dem hinteren Rand 4 der äusseren Umfangsfläche 2 je eine über die ganze Breite des Grundkörpers durchgehende Befestigungsleiste 6 bzw. 7 angeformt. Die vordere Befestigungsleiste 6 enthält zwei Bohrungen 8, und die hintere Befestigungsleiste 7 enthält zwei Bohrungen 9. Die Bohrungen 8 und 9 nehmen die Schrauben (nicht dargestellt) auf, mit denen das Rundkammsegment auf der Rundkammwalze R befestigt wird.In the known circular comb segment, which is shown in FIGS. 1 and 2, a fastening strip 6 or 7 that is continuous over the entire width of the base body is in each case on the base body 1 in front of the front edge 3 and behind the rear edge 4 of the outer peripheral surface 2 molded. The front fastening bar 6 contains two bores 8, and the rear fastening bar 7 contains two bores 9. The bores 8 and 9 receive the screws (not shown) with which the round comb segment is fastened on the round comb roller R.

In der Kämmaschine arbeiten die Rundkammsegmente jeweils mit einem nur in Fig. 1 angedeuteten Zangenaggregat zusammen, das aus einer Unterzange 10 und einer Oberzange 11 besteht. Das Zangenaggregat hält dem Rundkammsegment bei jeder Umdrehung der Rundkammwalze R jeweils einen Faserbart F von einer dem Zangenaggregat zugeführten Watte (nicht dargestellt) vor.In the combing machine, the circular comb segments each work with a pair of pliers, which is only indicated in FIG. 1 and consists of lower pliers 10 and upper pliers 11. The pliers unit holds the round comb segment in front of each round of the round comb roller R with a fiber beard F from a cotton wool (not shown) fed to the pliers unit.

Bei dem in den Fig. 1 und 2 gezeigten bekannten Rundkammsegment wird nun festgestellt, dass der Faserbart F vom Rundkammsegment nicht mehr einwandfrei durchgekämmt wird, wenn man mit höheren Geschwindigkeiten und/oder mit höheren Wattegewichten arbeitet. Es ist gefunden worden, dass eine wesentliche Ursache für diese Erscheinung in der vorderen Befestigungsleiste 6 liegt. Diese Befestigungsleiste 6 kommt mit dem Faserbart F in Berührung, bevor die Fasern von den vordersten Kämmnadeln oder Kämmgarnitur-Spitzen 5 erfasst werden. Einige der Fasern des Faserbartes F können dadurch wie in Fig. 1 angedeutet so weit nach aussen gestossen werden, dass der Faserbart F danach von den vordersten Kämmnadeln oder Kämmgarnitur-Spitzen 5 nicht mehr vollständig durchstochen wird.In the known circular comb segment shown in FIGS. 1 and 2, it is now found that the fiber beard F is no longer combed properly by the circular comb segment when working at higher speeds and / or with higher cotton weights. It has been found that an essential cause for this phenomenon lies in the front fastening strip 6. This fastening strip 6 comes into contact with the fiber beard F before the fibers are caught by the foremost combing needles or combing attachment tips 5. As indicated in FIG. 1, some of the fibers of the fiber beard F can be pushed so far outwards that the fiber beard F is then no longer completely pierced by the foremost combing needles or combing tips 5.

Bei den in den Fig. 3 bis 12 dargestellten erfindungsgemässen Rundkammsegmenten ist daher die durchgehende vordere Befestigungsleiste 6 weggelassen und stattdessen in Umfangsrichtung vor der Ebene E ein freier Raum vorhanden, der sich in radialer Richtung vom vorderen Rand 3 aus zumindest über den grössten Teil der Dicke des Grundkörpers 1 erstreckt und in Richtung der Breite des Grundkörpers 1 von der Mitte M des vorderen Randes 3 aus nach beiden Seiten hin über zumindest den grössten Teil der Breite des Grundkörpers erstreckt. Dadurch ist sichergestellt, dass der dem Rundkammsegment vorgehaltene Faserbart von den vordersten Kämmnadeln oder Kämmgarnitur-Spitzen 5, die noch über die Ebene E hinaus nach vorn vorstehen, vollständig durchstochen und in den Rundkamm gezogen wird.3 to 12, the continuous front fastening strip 6 is therefore omitted and instead there is a free space in the circumferential direction in front of the plane E, which extends radially from the front edge 3 at least over most of the thickness of the base body 1 and extends in the direction of the width of the base body 1 from the center M of the front edge 3 to both sides over at least the largest part of the width of the base body. This ensures that the fiber beard held in front of the circular comb segment is completely pierced by the foremost combing needles or combing set tips 5, which still protrude forward beyond plane E, and drawn into the circular comb.

Die hintere Befestigungsleiste 7 mit den beiden Bohrungen 9 kann wie dargestellt beibehalten werden.The rear mounting strip 7 with the two holes 9 can be maintained as shown.

Bei dem Rundkammsegment gemäss Fig. 3 und 4 ist in der äusseren Umfangsfläche 2 benachbart zum vorderen Rand 3 und benachbart zu den Seitenrändern 12 der Umfangsfläche 2 je eine Ausnehmung 13 vorgesehen, von der eine radiale Bohrung 14 durch den Grundkörper 1 ausgeht. Die Bohrungen 14 nehmen je eine Schraube (nicht dargestellt) auf, die in die Rundkammwalze R geschraubt wird, um das Rundkammsegment im Bereich des vorderen Randes 3 auf der Rundkammwalze R festzuhalten. Wegen der Ausnehmungen 13 erstreckt sich die vorderste Reihe der Kämmgarnituren 5 nicht über die ganze Breite des Grundkörpers 1. Da die Ausnehmungen 13 jedoch ganz aussen, benachbart zu den Seitenrändern 12, angeordnet sind und nicht mehr als je etwa 5% der Breite des Grundkörpers 1 einnehmen, ergeben sich dadurch keine Nachteile. Dafür erstreckt sich der freie Raum vor der Ebene E bei diesem Rundkammsegment sowohl in radialer Richtung vom vorderen Rand 3 aus über die ganze Dicke d des Grundkörpers 1 als auch in Richtung der Breite des Grundkörpers 1 über die ganze Breite desselben.3 and 4, a recess 13 is provided in the outer peripheral surface 2 adjacent to the front edge 3 and adjacent to the side edges 12 of the peripheral surface 2, from which a radial bore 14 extends through the base body 1. The holes 14 each receive a screw (not shown) which is screwed into the circular comb roller R in order to hold the circular comb segment in the region of the front edge 3 on the circular comb roller R. Because of the recesses 13, the foremost row of the combing sets 5 does not extend over the entire width of the base body 1. However, since the recesses 13 are arranged on the outside, adjacent to the side edges 12, and no more than about 5% of the width of the base body 1 take, there are no disadvantages. For this purpose, the free space in front of the plane E extends in this circular comb segment both in the radial direction from the front edge 3 over the entire thickness d of the base body 1 and in the direction of the width of the base body 1 over the entire width of the same.

Bei dem Rundkammsegment gemäss Fig. 5 und 6 sind am Grundkörper 1 im Bereich der beiden Enden des vorderen Randes Ansätze 15 angeformt, die je eine Bohrung 16 zur Aufnahme einer in die Rundkammwalze R schraubbaren Befestigungsschraube (nicht dargestellt) aufweisen. Die Ansätze 15 können sich wie dargestellt über die Ebene E hinaus nach vorn erstrecken. Der freie Raum vor der Ebene E erstreckt sich dann im mittleren Bereich der Breite des Grundkörpers 1 vom vorderen Rand 3 aus über die ganze Dicke des Grundkörpers 1, wobei dieser mittlere Bereich, von der Mitte M aus bis zu den beiden Ansätzen 15, mindestens 80% und vorzugsweise mindestens 90% der Breite des Grundkörpers 1 ausmacht. Anstelle der Ansätze 15 könnten aber auch, wie mit unterbrochenen Linien dargestellt, Ansätze 15′ vorgesehen sein, die sich hinter der Ebene E nach den Seiten hin erstrecken.5 and 6 are in the round comb segment lugs 15 are formed on the base body 1 in the region of the two ends of the front edge, each of which has a bore 16 for receiving a fastening screw (not shown) which can be screwed into the circular comb roller R. The projections 15 can extend beyond the plane E as shown. The free space in front of the plane E then extends in the central region of the width of the base body 1 from the front edge 3 over the entire thickness of the base body 1, this central region, from the center M up to the two lugs 15, at least 80 % and preferably at least 90% of the width of the base body 1. Instead of the approaches 15 but, as shown with broken lines, approaches 15 'may be provided, which extend behind the plane E to the sides.

Bei dem Rundkammsegment gemäss Fig. 7 und 8 ist an den Grundkörper 1 an seiner Vorderseite ein Vorsprung 17 angeformt, der über die ganze Breite des Grundkörpers 1 durchgehend sein kann, damit der Grundkörper 1 als gezogener Körper hergestellt werden kann. Bei den beiden Enden der Breite des Grundkörpers 1 sind Klemmplatten 18 vorgesehen, die je eine Bohrung 19 zur Aufnahme einer in die Rundkammwalze R schraubbaren Befestigungsschraube aufweisen. Die Klemmplatten 18 besitzen jeweils einen Klemmansatz 18a, mit dem sie am Vorsprung 17 angreifen, um diesen gegen die Umfangsfläche der Rundkammwalze R zu klemmen. Im mittleren Bereich der Breite des Grundkörpers 1, von der Mitte M aus bis zu den beiden Klemmplatten 18, erstreckt sich der freie Raum vor der Ebene E in radialer Richtung vom vorderen Rand 3 aus bis zum Vorsprung 17 und damit, da die Höhe des Vorsprungs relativ klein ist, über den grössten Teil der Dicke des Grundkörpers, nämlich über wenigstens etwa 75 bis 80% dieser Dicke. Der radiale Abstand vom vorderen Rand 3 bis zum Vorsprung 17 sollte wenigstens 10 mm und vorzugsweise wenigstens 12 mm betragen. Der genannte mittlere Bereich der Breite des Grundkörpers 1 erstreckt sich auch hier über wenigstens 80 bis 90% der ganzen Breite des Grundkörpers 1.7 and 8, a projection 17 is formed on the front of the base body 1, which can be continuous over the entire width of the base body 1, so that the base body 1 can be produced as a drawn body. At the two ends of the width of the base body 1, clamping plates 18 are provided, each of which has a bore 19 for receiving a fastening screw which can be screwed into the circular comb roller R. The clamping plates 18 each have a clamping projection 18a, with which they engage on the projection 17 in order to clamp it against the peripheral surface of the circular comb roller R. In the central region of the width of the base body 1, from the center M to the two clamping plates 18, the free space in front of the plane E extends in the radial direction from the front edge 3 to the projection 17 and thus, since the height of the projection is relatively small, over most of the thickness of the base body, namely over at least about 75 to 80% of this thickness. The radial distance from the front edge 3 to the projection 17 should be at least 10 mm and preferably at least 12 mm. The said middle range of the width of the Base body 1 also extends here over at least 80 to 90% of the entire width of base body 1.

Das Rundkammsegment gemäss Fig. 9 und 10 unterscheidet sich von demjenigen gemäss Fig. 7 und 8 im wesentlichen nur dadurch, dass der Grundkörper 1 anstelle des Vorsprungs 17 eine Nut 20 aufweist, in welche die Klemmansätze 18a′ der bei den Enden der Breite des Grundkörpers 1 angeordneten Klemmplatten 18′ eingreifen. Dadurch erstreckt sich der freie Raum vor der Ebene E im mittleren Bereich der Breite des Grundkörpers 1, zwischen den beiden Klemmplatten 18′, in radialer Richtung vom vorderen Rand 3 aus über die ganze Dicke des Grundkörpers 1.9 and 10 differs from that according to FIGS. 7 and 8 essentially only in that the base body 1 instead of the projection 17 has a groove 20 into which the clamping lugs 18a 'at the ends of the width of the base body 1 arranged clamping plates 18 'engage. As a result, the free space in front of the plane E extends in the central region of the width of the base body 1, between the two clamping plates 18 ', in the radial direction from the front edge 3 over the entire thickness of the base body 1.

Bei dem Rundkammsegment gemäss Fig. 11 und 12 ist an den Grundkörper 1 an seiner Vorderseite ein Vorsprung 21 angeformt, in welchem bei den Enden der Breite des Grundkörpers 1 Bohrungen 22 zur Aufnahme von in die Rundkammwalze zu schraubenden Befestigungsschrauben angeordnet sind. Der Vorsprung 21 kann über die ganze Breite des Grundkörpers 1 durchgehend sein. Der Vorsprung 21 ist jedoch vom vorderen Rand 3 aus gemessen so weit radial nach innen verschoben und in die Rundkammwalze R eingelassen, dass sich der freie Raum vor der Ebene E in radialer Richtung über wenigstens 80% und vorzugsweise wenigstens 90% der hinter dem Vorsprung 21 gemessenen Dicke d des Grundkörpers 1 erstreckt. Der radiale Abstand vom vorderen Rand 3 bis zum Vorsprung 21 sollte wenigstens 10 mm und vorzugsweise wenigstens 12 mm betragen.11 and 12, a projection 21 is formed on the base body 1 on its front, in which 1 holes 22 are arranged at the ends of the width of the base body for receiving fastening screws to be screwed into the round comb roller. The projection 21 can be continuous over the entire width of the base body 1. However, the protrusion 21 is displaced radially inward from the front edge 3 and inserted into the circular comb roller R such that the free space in front of the plane E in the radial direction is at least 80% and preferably at least 90% of that behind the protrusion 21 measured thickness d of the base body 1 extends. The radial distance from the front edge 3 to the projection 21 should be at least 10 mm and preferably at least 12 mm.
