Definitions
- the invention relates to a system for producing structured textile velor needle felt webs from a pre-needled fleece made of staple fibers, which consists of a non-woven machine, a pre-needle machine and a velor needle machine.
- Plants of the aforementioned type have already become known.
- the most problematic part of such systems is the conventional velor needle machine.
- the velor needle felt webs produced by means of the known systems leave a lot to be desired in various respects. In particular, the uniformity and freedom of orientation of the product image cannot be achieved with their help.
- the strength of the needle felt web is not sufficient and finally the machines used hitherto require a relatively high amount of energy, which in turn means that the fibers are damaged or torn to a greater or lesser extent.
- the invention has for its object to provide a system for producing textured velor needle felt webs with the lowest possible basis weight, which are characterized by a great uniformity and freedom of orientation of the product image and a high strength of the needle felt web, and the operation of which requires the lowest possible energy consumption .
- the velor needle machine is equipped with an endless brush belt carrying the fleece to be needled and serving as a backing pad, which is composed of a plurality of brush plates carrying the tufts of bristles is, the outer edges of which are formed in a zigzag shape such that the edges of adjacent brush plates engage in such a way that the bristle tufts along the outer edges have the same distances from one another as those in the inner region of the brush plate, that the bristles of the bristle tufts are conical at their free end or are ground in a wedge shape, that the hold-down plate rests on the nonwoven web and is pressed against it, and that crown needles are used for the three-dimensional structuring of the pre-needled nonwoven.
- the nonwoven needle machine is equipped with at least two needle bars arranged parallel to one another, either both needle bars being moved by a common drive mechanism or each needle bar being assigned its own drive mechanism so that the work cycles are offset from one another.
- the pre-needle machine can advantageously also in the same way be designed like the velor needle machine, but without this being equipped with crown needles.
- the stitch pad in the form of an endless bristle band evenly covered with bristles over the entire surface offers an excellent prerequisite for a largely uniform, homogeneous pre-needling of the pile of the pile web to a pre-needled fleece of particularly good uniformity, which was previously not achievable. This allows the quality of the end product to be further improved, particularly with regard to its strength in the final state.
- the system in question for producing structured textile velor needle felt webs consists of a fleece laying machine 11, by means of which the large-volume nonwoven web 12 to be pre-needled is formed by superimposing a plurality of pile layers. Downstream of the fleece laying machine 11 is the pre-needle machine 13, by means of which the Nonwoven web 12 is compressed. The pre-needled nonwoven web 14 treated in this way is finally fed to the velor needle machine 15, in which the smooth nonwoven web 14 receives its three-dimensional structuring through an orientation-free pile formation.
- a nonwoven drafting device 16 is connected between the pre-needle machine 13 and the velor needle machine 15 in order to impart certain desired properties to the end product by treating the nonwoven 14 in this drawing device, in particular with regard to easy and clean deformation of the goods.
- the pre-needle machine 13 can have the usual construction of the machine used for such purposes. However, it is particularly advantageous if a brush belt is used as the stitch support and transport means for the web 12 or 14, as the velor needle machine 15 necessarily has.
- a brush band 21 serves as a stitch pad for the crown needles 23 seated on the two needle beams 22.
- the brush band 21 consists of numerous brush plates 24, which are regularly arranged with bristle bushes 25, as can be seen in particular in FIG. 2.
- the outer edges 26 of the brush plates 24 are formed in a zigzag shape, so that respectively adjacent brush plates 24 can mesh with one another, so that the distances of the outermost bristle tufts 25 along the outer edges of adjacent brush plates 24 have the same distances in every direction as the bristle tufts 25 in the inner region of the Brush plate 24.
- the brush plates 24 are provided on their rear side with retaining strips 27, which are provided on opposite sides with a groove 28, into which the legs 29 engage from fastening rails 30 which extend across the width of the brush band 21.
- the fastening rails 30 are fastened to endlessly rotating conveyor chains or belts or the like.
- the bristles are either tapered or wedge-shaped, which ensures a longer service life of the brush belt 21.
- this measure also avoids the formation of burrs at the tip of each bristle, which has the effect of a barb, by means of which the nonwoven fabric or individual fibers of the same are undesirably retained.
- the aforementioned measure also serves to improve the quality of the product.
- the hold-down plate through the openings of which the needles are pierced into and through the pre-needled nonwoven fabric, is firmly arranged.
- crown needles for the purpose of three-dimensional structuring of the pre-needled nonwoven fabric gives a voluminous velor needle felt web of extraordinary uniformity and structural freedom, which was previously not available with any of the previously known machines.
- the crown needles are such needles in which the notches on the needle shaft are all distributed over the circumference at the same distance from the needle tip.
- the fork nadein commonly used so far produces a relatively lean pile of goods.
- crown needles to be used according to the invention are that the puncture forces are considerably lower than those which occur when using fork needles, so that the energy requirement of the velor needle machine is considerably reduced.
- this also means that the damage to the fibers by the needles is substantially less, which in turn increases the strength of the velor needle felt web.
- the velor needle machine 15 has two needle bars 22, as can be seen from FIG. 1.
- a needle felt web which has elastic properties that are as uniform as possible in all directions. For such applications, it is advantageous to switch on a nonwoven drafting device 16 between the pre-needle machine 13 and the velor needle machine 15, as shown in FIG. 1.
- the system designed according to the invention makes it possible to obtain extremely evenly structured textile needle felt webs, the appearance of which is characterized by great uniformity and freedom of orientation as well as high strength even with low basis weights draws.

Abstract
Description
Die Erfindung betrifft eine Anlage zum Herstellen von strukturierten textilen Velournadelfilzbahnen aus einem vorgenadelten Vlies aus Stapelfasern, welche aus einer Viiesiegemaschine, einer Vornadelmaschine und einer Velournadelmaschine besteht. Anlagen der vorbezeichneten Art sind bereits bekanntgeworden. Der problematischste Teil solcher Anlagen ist die Velournadelmaschine herkömmlicher Bauart. Die mittels der bekannten Anlagen hergestellten Velournadelfilzbahnen lassen in verschiedenster Hinsicht zu wünschen übrig. Insbesondere läßt sich mit ihrer Hilfe keine Gleichmäßigkeit und Orientierungsfreiheit des Warenbildes erreichen. Weiterhin ist die Festigkeit der Nadelfilzbahn nicht ausreichend und schließlich erfordern die bisher eingesetzten Maschinen einen relativ hohen Energiebedarf, was wiederum zur Folge hat, daß die Fasern mehr oder weniger stark beschädigt oder zerrissen werden.The invention relates to a system for producing structured textile velor needle felt webs from a pre-needled fleece made of staple fibers, which consists of a non-woven machine, a pre-needle machine and a velor needle machine. Plants of the aforementioned type have already become known. The most problematic part of such systems is the conventional velor needle machine. The velor needle felt webs produced by means of the known systems leave a lot to be desired in various respects. In particular, the uniformity and freedom of orientation of the product image cannot be achieved with their help. Furthermore, the strength of the needle felt web is not sufficient and finally the machines used hitherto require a relatively high amount of energy, which in turn means that the fibers are damaged or torn to a greater or lesser extent.
Zum Vornadeln von aus mehreren Lagen bestehenden Flor- oder Vliesbahnen ist vorgeschlagen worden, eine Vornadelmaschine einzusetzen, bei welcher die Stichunterlage aus einem endlosen Förderband besteht, welches mit Borsten besetzt ist. Eine derartige Maschine arbeitet jedoch nicht zur vollen Zufriedenheit, da die Nadelung verhältnismäßig ungleichmäßig ist und insbesondere Streifenbildungen auftreten, die konstruktionsbedingt sind. Daher ist eine derartige Maschine als Velournadelmaschine überhaupt nicht einsetzbar.For the pre-needling of pile or fleece webs consisting of several layers, it has been proposed to use a pre-needle machine in which the stitch underlay consists of an endless conveyor belt which is covered with bristles. However, such a machine does not work to full satisfaction, since the needling is relatively uneven and, in particular, streaking occurs, which are due to the design. Therefore, such a machine cannot be used as a velor needle machine at all.
Der Erfindung liegt die Aufgabe zugrunde, eine Anlage zum Herstellen von strukturierten textilen Velournadelfilzbahnen mit möglichst niedrigem Flächengewicht zu schaffen, welche sich durch eine große Gleichmäßigkeit und Orientierungsfreiheit des Warenbildes sowie eine hohe Festigkeit der Nadelfilzbahn auszeichnen, und zu deren Betrieb ein möglichst niedriger Energiebedarf erforderlich ist.The invention has for its object to provide a system for producing textured velor needle felt webs with the lowest possible basis weight, which are characterized by a great uniformity and freedom of orientation of the product image and a high strength of the needle felt web, and the operation of which requires the lowest possible energy consumption .
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, die in Betracht kommende Anlage in der Weise auszubilden, daß wenigstens die Velournadelmaschine mit einem das zu nadelnde Vlies tragenden und als Stichunterlage dienenden endlosen Bürstenband ausgerüstet ist, welches aus einer Vielzahl von die Borstenbüschel tragenden Bürstenplatten zusammengesetzt ist, deren Außenkanten zickzackförmig derart ausgebildet sind, daß die Kanten jeweils einander benachbarter Bürstenplatten in der Weise ineinandergreifen, daß die Borstenbüschel entlang den Außenkanten die gleichen Abstände voneinander haben wie die im inneren Bereich der Bürstenplatte, daß die Borsten der Borstenbüschel an ihrem freien Ende konisch oder keilförmig angeschliffen sind, daß die Niederhalteplatte auf der Faservliesbahn aufliegt und gegen diese niedergedrückt wird und daß zur dreidimensionalen Strukturierung des vorgenadelten Faservlieses Kronennadeln Anwendung finden.To achieve this object, it is proposed according to the invention to design the system in question in such a way that at least the velor needle machine is equipped with an endless brush belt carrying the fleece to be needled and serving as a backing pad, which is composed of a plurality of brush plates carrying the tufts of bristles is, the outer edges of which are formed in a zigzag shape such that the edges of adjacent brush plates engage in such a way that the bristle tufts along the outer edges have the same distances from one another as those in the inner region of the brush plate, that the bristles of the bristle tufts are conical at their free end or are ground in a wedge shape, that the hold-down plate rests on the nonwoven web and is pressed against it, and that crown needles are used for the three-dimensional structuring of the pre-needled nonwoven.
Vorteilhafterweise ist die Vliesnadelmaschine mit wenigstens zwei parallel zueinander angeordneten Nadelbalken ausgerüstet, wobei entweder beide Nadelbalken von einem gemeinsamen Antriebsmechanismus bewegt werden oder jedem Nadelbalken ein eigener Antriebsmechanismus zugeordnet ist, so daß die Arbeitstakte zueinander versetzt sind.Advantageously, the nonwoven needle machine is equipped with at least two needle bars arranged parallel to one another, either both needle bars being moved by a common drive mechanism or each needle bar being assigned its own drive mechanism so that the work cycles are offset from one another.
Weiterhin ist es von Vorteil, zwischen der Vornadelmaschine und der Velournadelmaschine ein Faservliesstreckwerk einzuschalten, was insbesondere dann in Betracht kommt, wenn das erhaltene Endprodukt im Rahmen der weiteren Verarbeitung einer Verformung durch Tiefziehen bzw. Prägen unterzogen werden soll. Durch das Verstrecken des Vlieses erreicht man eine Faserumorientierung mit dem Ziele, der Ware bessere isotrope elastische Eigenschaften zu vermitteln.Furthermore, it is advantageous to switch on a nonwoven drafting machine between the pre-needle machine and the velor needle machine, which is particularly suitable if the end product obtained is to be subjected to deformation by deep drawing or embossing in the course of further processing. By stretching the fleece, fiber orientation is achieved with the aim of imparting better isotropic elastic properties to the goods.
Wenn auch die erfindungsgemäß ausgebildete Velournadelmaschine in besonderem Maße dazu geeignet ist, die dreidimensionale Strukturierung des ursprünglich glatten Faservlieses herbeizuführen, um das gewünschte gleichmäßige Produkt mit homogenem in keiner Weise orientiertem Flor und hoher Festigkeit zu erhalten, so kann auch die Vornadelmaschine vorteilhafterweise in der gleichen Weise ausgebildet sein wie die Velournadelmaschine, ohne daß diese jedoch mit Kronennadeln bestückt ist. Die Stichunterlage in Form eines endlosen und über die ganze Fläche gleichmäßig mit Borsten besetzten Bürstenbandes bietet eine hervorragende Voraussetzung für ein weitgehend gleichmäßig homogenes Vornadeln des Flores der Florbahn zu einem vorgenadelten Vlies besonders guter Gleichmäßigkeit, wie diese bisher nicht erreichbar war. Dadurch läßt sich die Qualität des Endprodukts noch weiter verbessern, insbesondere im Hinblick auf seine Festigkeit im Endzustand.Even if the velor needle machine designed according to the invention is particularly suitable for bringing about the three-dimensional structuring of the originally smooth non-woven fabric in order to obtain the desired uniform product with a homogeneous, in no way oriented pile and high strength, the pre-needle machine can advantageously also in the same way be designed like the velor needle machine, but without this being equipped with crown needles. The stitch pad in the form of an endless bristle band evenly covered with bristles over the entire surface offers an excellent prerequisite for a largely uniform, homogeneous pre-needling of the pile of the pile web to a pre-needled fleece of particularly good uniformity, which was previously not achievable. This allows the quality of the end product to be further improved, particularly with regard to its strength in the final state.

Wie Fig. 1 erkennen läßt, besteht die in Betracht kommende Anlage zum Herstellen strukturierter textiler Velournadelfilzbahnen aus einer Vlieslegemaschine 11, mittels welcher die vorzunadelnde großvolumige Faservliesbahn 12 durch Übereinanderlegen mehrerer Florschichten gebildet wird. Der Vlieslegemaschine 11 nachgeschaltet ist die Vornadelmaschine 13, mittels welcher die Faservliesbahn 12 verdichtet wird. Die so behandelte vorgenadelte Faservliesbahn 14 wird schließlich der Velournadelmaschine 15 zugeführt, in welcher die glatte Faservliesbahn 14 ihre dreidimensionale Strukturierung durch eine orientierungsfreie Polbildung erhält.As can be seen in FIG. 1, the system in question for producing structured textile velor needle felt webs consists of a
In bestimmten Fällen ist zwischen die Vornadelmaschine 13 und die Velournadelmaschine 15 ein Faservliesstreckwerk 16 eingeschaltet, um durch die Behandlung des Vlieses 14 in diesem Streckwerk dem Endprodukt bestimmte gewünschte Eigenschaften zu vermitteln, insbesondere im Hinblick auf eine leichte und saubere Verformung der Ware. Die Vornadelmaschine 13 kann die übliche Konstruktion der für solche Zwecke eingesetzten Maschine aufweisen. Besonders vorteilhaft ist es jedoch, wenn als Stichunterlage und Transportmittel für die Bahn 12 bzw. 14 ein Bürstenband Verwendung findet, wie es die Velournadelmaschine 15 notwendigerweise aufweist.In certain cases, a
Bei der Velournadelmaschine 15 dient ein Bürstenband 21 als Stichunterlage für die an den beiden Nadelbalken 22 sitzenden Kronennadeln 23. Das Bürstenband 21 besteht aus zahlreichen Bürstenplatten 24, welche in regelmäßiger Anordnung mit Borstenbüschein 25 besetzt sind, wie dies insbesondere Fig. 2 erkennen läßt. Die Außenkanten 26 der Bürstenplatten 24 sind zickzackförmig ausgebildet, so daß jeweils benachbarte Bürstenplatten 24 verzahnend ineinandergreifen können, so daß die Abstände der äußersten Borstenbüschel 25 entlang den Außenkanten einander benachbarter Bürstenplatten 24 in jeder Richtung die gleichen Abstände haben wie die Borstenbüschel 25 im inneren Bereich der Bürstenplatte 24.In the
Die Bürstenplatten 24 sind an ihrer Rückseite mit Halteleisten 27 versehen, die auf einander gegenüberliegenden Seiten mit einer Nut 28 versehen sind, in welche die Schenkel 29 von sich über die Breite des Bürstenbandes 21 erstreckende Befestigungsschienen 30 eingreifen. Die Befestigungsschienen 30 sind an endlos umlaufenden Förderketten oder -bändern oder dgl. befestigt.The
Durch eine derartige Ausbildung der Bürstenplatten und Anordnung der Borstenbüschel 25 wird ein absolut gleichmäßiges Bürstenband 21 erhalten, welches Voraussetzung für ein absolut gleichmäßiges Endprodukt ist.With such a design of the brush plates and arrangement of the
Um zu vermeiden, daß beim Auftreffen der Nadelspitze auf eine Borste eine sogenannte Pilzbildung eintritt, sind die Borsten entweder konisch oder keilförmig angeschliffen, was eine längere Lebensdauer des Bürstenbandes 21 gewährleistet. Diese Maßnahme vermeidet aber auch eine Gratbildung an der Spitze einer jeden Borste, weiche die Wirkung eines Widerhakens hat, durch weiche das Faservlies bzw. einzelne Fasern desselben in unerwünschter Weise festgehalten werden. Somit dient die vorerwähnte Maßnahme aber auch der Qualitätsverbesserung des Produkts.In order to avoid the occurrence of a so-called fungus formation when the needle tip hits a bristle, the bristles are either tapered or wedge-shaped, which ensures a longer service life of the
Bei den bisher bekannten Nadelmaschinen ist die Niederhalteplatte, durch deren Öffnungen hindurch die Nadeln in und durch das vorgenadelte Faservlies gestochen werden, fest angeordnet. Dies hat zur Folge, daß die Faservliesbahn beim Durchlauf eine unerwünschte Ftatterbewegung ausführt, die dadurch vermieden werden kann, daß man die Niederhalteplatte auf der Faservliesbahn aufliegen läßt, und zwar vorzugsweise unter leichtem Druck, was möglich ist, weil die das Faservlies abstützenden Borsten des Bürstenbandes 21 eine gewisse Eigenelastizität besitzen. Durch diese Maßnahme läßt sich die Qualität des Endprodukts und insbesondere dessen Warenoberfläche verbessern.In the previously known needling machines, the hold-down plate, through the openings of which the needles are pierced into and through the pre-needled nonwoven fabric, is firmly arranged. This has the consequence that the nonwoven web performs an undesirable filter movement during the passage, which can be avoided by letting the hold-down plate rest on the nonwoven web, preferably under light pressure, which is possible because the bristles of the brush band supporting the
Durch die vorgeschlagene Anwendung von Kronennadeln zum Zwecke der dreidimensionalen Strukturierung des vorgenadelten Faservlieses wird eine voluminöse Velournadelfilzbahn außerordentlicher Gleichmäßigkeit und Strukturfreiheit erhalten, die bisher mit keiner der vorbekannten Maschinen erhältlich war. Bei den Kronennadeln handelt es sich um solche Nadeln, bei welchen die Kerben am Nadelschaft sämtlichst im gleichen Abstand von der Nadelspitze über den Umfang verteilt angeordnet sind. Die bisher üblicherweise verwendeten Gabelnadein erzeugen erfahrungsgemäß und bekannterweise einen relativ mageren Pol der Ware.The proposed use of crown needles for the purpose of three-dimensional structuring of the pre-needled nonwoven fabric gives a voluminous velor needle felt web of extraordinary uniformity and structural freedom, which was previously not available with any of the previously known machines. The crown needles are such needles in which the notches on the needle shaft are all distributed over the circumference at the same distance from the needle tip. Experience has shown that the fork nadein commonly used so far produces a relatively lean pile of goods.
Die erfindungsgemäß anzuwendenden Kronennadeln haben zur Folge, daß die Einstichkräfte gegenüber denjenigen, die bei der Anwendung von Gabelnadeln auftreten, wesentlich geringer sind, so daß dadurch der Energiebedarf der Velournadelmaschine in beträchtlichem Umfange herabgesetzt ist. Dies bedeutet aber auch, daß die Faserschädigung durch die Nadeln wesentlich geringer ist, was wiederum einer Erhöhung der Festigkeit der Velournadelfilzbahn zugute kommt.The consequence of the crown needles to be used according to the invention is that the puncture forces are considerably lower than those which occur when using fork needles, so that the energy requirement of the velor needle machine is considerably reduced. However, this also means that the damage to the fibers by the needles is substantially less, which in turn increases the strength of the velor needle felt web.
Einerseits wegen des niedrigen Energiebedarfs, andererseits aber wegen einer besseren Warenqualität weist die Velournadelmaschine 15 zwei Nadelbalken 22 auf, wie dies aus Fig. 1 ersichtlich ist. Es ist aber auch möglich, weitere Nadelbalken vorzusehen, wobei deren Bewegung derart gesteuert sein kann, daß die Arbeitshübe jeweils aufeinanderfolgen.On the one hand because of the low energy requirement, but on the other hand because of better product quality, the
Soll die Velournadelfilzbahn beispielsweise durch Tiefziehen oder Prägen einer mehr oder weniger starken Formänderung unterzogen werden, was beispielsweise im Hinblick auf bestimmte Ausstattungselemente im Automobilbau von Bedeutung ist, so ist eine Nadelfilzbahn erwünscht, die möglichst in allen Richtungen gleichmäßige elastische Eigenschaften aufweist. Für derartige Anwendungszwecke ist es vorteilhaft, zwischen der Vornadelmaschine 13 und der Velournadelmaschine 15 noch ein Faservliesstreckwerk 16 einzuschalten, wie dies in Fig. 1 dargestellt ist.If the velor needle felt web is to be subjected to a more or less strong change in shape, for example by deep drawing or embossing, which is important, for example, with regard to certain equipment elements in automobile construction, then a needle felt web is desired which has elastic properties that are as uniform as possible in all directions. For such applications, it is advantageous to switch on a
Die erfindungsgemäß ausgebildete Anlage ermöglicht es, außerordentlich gleichmäßig strukturierte textile Nadelfilzbahnen zu erhalten, deren Warenbild sich durch eine große Gleichmäßigkeit und Orientierungsfreiheit sowie eine hohe Festigkeit selbst bei geringen Flächengewichten auszeichnet.The system designed according to the invention makes it possible to obtain extremely evenly structured textile needle felt webs, the appearance of which is characterized by great uniformity and freedom of orientation as well as high strength even with low basis weights draws.
