Eine derartige Nadelmaschine ist in besonderem Maße dazu geeignet, eine hohe Einstichdichte der Nadeln in das textile Flächengebilde zu gewährleisten und eine besonders gleichmäßige Vernadelung des textilen Flächengebildes zu bewirken.Such a needling machine is particularly suitable for ensuring a high penetration density of the needles into the textile fabric and for bringing about a particularly uniform needling of the textile fabric.
In einer bevorzugten Ausführungsform beträgt die Anzahl der nebeneinander angeordneten Drähte der oberen Stütz- und Führungsmittel mindestens 250 pro Meter Arbeitsbreite quer zur Förderrichtung, bevorzugt mindestens 400 pro Meter Arbeitsbreite, mehr bevorzugt mindestens 500 pro Meter Arbeitsbreite, und die Anzahl der nebeneinander angeordneten Drähte der unteren Stütz- und Führungsmittel beträgt mindestens 250 pro Meter Arbeitsbreite quer zur Förderrichtung, bevorzugt mindestens 400 pro Meter Arbeitsbreite, mehr bevorzugt mindestens 500 pro Meter Arbeitsbreite. Auf diese Weise können textile Flächengebilde mit üblichen Breiten in der Vernadelungszone sicher geführt und gestützt werden.In a preferred embodiment, the number of juxtaposed wires of the upper support and guiding means is at least 250 per meter of working width across the conveying direction, preferably at least 400 per meter of working width, more preferably at least 500 per meter of working width, and the number of juxtaposed wires of the lower Support and guide means is at least 250 per meter of working width transversely to the conveying direction, preferably at least 400 per meter of working width, more preferably at least 500 per meter of working width. In this way, flat textile structures with the usual widths can be safely guided and supported in the needling zone.
Es ist bevorzugt, dass die Drähte der oberen Stütz- und Führungsmittel und die Drähte der unteren Stütz- und Führungsmittel parallel zueinander verlaufen. Auf diese Weise wird die Führung des textilen Flächengebildes in der Vernadelungszone optimiert.It is preferred that the wires of the upper support and guide means and the wires of the lower support and guide means run parallel to one another. In this way, the guidance of the textile fabric in the needling zone is optimized.
Jeder Draht verläuft vorzugsweise in Förderrichtung F des textilen Flächengebildes.Each wire preferably runs in the conveying direction F of the textile fabric.
In einer bevorzugten Ausgestaltung sind die Drähte der oberen Stütz- und Führungsmittel und die Drähte der unteren Stütz- und Führungsmittel in vertikaler Richtung miteinander ausgerichtet. Somit wird gewährleistet, dass sämtliche Nadeln beim Einstichvorgang nicht mit den Drähten der oberen Stütz- und Führungsmittel und der unteren Stütz- und Führungsmittel kollidieren.In a preferred embodiment, the wires of the upper support and guide means and the wires of the lower support and guide means are aligned with one another in the vertical direction. This ensures that none of the needles collide with the wires of the upper support and guide means and the lower support and guide means during the puncturing process.
Es ist bevorzugt, dass die oberen Durchtrittsöffnungen zwischen den Drähten der oberen Stütz- und Führungsmittel eine Breite zwischen 0,5 mm und 10 mm, bevorzugt zwischen 0,7 mm und 8 mm, mehr bevorzugt zwischen 0,8 mm und 5 mm aufweisen.It is preferred that the upper passage openings between the wires of the upper support and guide means have a width between 0.5 mm and 10 mm, preferably between 0.7 mm and 8 mm, more preferably between 0.8 mm and 5 mm.

Somit können nach Art von Klaviersaiten eine Nachjustierung der Drahtspannung und ein Austausch von Drähten auf einfache Weise erfolgen.In a preferred embodiment, the needle loom also has a tensioning device for each wire. A readjustment of the wire tension and an exchange of wires can thus be carried out in a simple manner in the manner of piano strings.
In bevorzugter Ausgestaltung ist zwischen der Spanneinrichtung und der Vernadelungszone auch eine Umlenkeinrichtung für jeden Draht angeordnet, mittels derer der jeweilige Draht um einen Winkel von zwischen 60° und 120°, bevorzugt zwischen 70° und 110°, mehr bevorzugt zwischen 80° und 100°, bezogen auf seine Anordnung in der Vernadelungszone umgelenkt ist. Dadurch werden die Drähte in einem Bereich außerhalb der Vernadelungszone nach oben bzw. nach unten umgelenkt und geben das textile Flächengebilde ungehindert frei.In a preferred embodiment, a deflection device for each wire is also arranged between the tensioning device and the needling zone, by means of which the respective wire is rotated through an angle of between 60 ° and 120 °, preferably between 70 ° and 110 °, more preferably between 80 ° and 100 ° , is deflected based on its arrangement in the needling zone. As a result, the wires are deflected upwards or downwards in an area outside the needling zone and release the textile fabric unhindered.
In einer bevorzugten Ausgestaltung sind die Nadeln in jedem Nadelbrett in einer Dichte von mindestens 500 Nadeln/dm2, bevorzugt mindestens 1.000 Nadeln/dm2, mehr bevorzugt mindestens 1.500 Nadeln/dm2 angeordnet. Derart hohe Nadeldichten führen zu einem besonders gleichmäßigen Stichbild im verfestigten Endprodukt.In a preferred embodiment, the needles are arranged in each needle board at a density of at least 500 needles / dm 2 , preferably at least 1,000 needles / dm 2 , more preferably at least 1,500 needles / dm 2 . Such high needle densities lead to a particularly uniform stitch pattern in the solidified end product.
In einer bevorzugten Ausführungsform sind die Nadeln in Nadelmodulen angeordnet, wobei jedes Nadelmodul eine Vielzahl von Nadeln aufweist, und wobei die Nadelmodule in Ausnehmungen oder Trägern des mindestens einen Nadelbretts aufgenommen und dort befestigt sind. Die Anordnung der Nadeln in Nadelmodulen hat mehrere Vorteile. So können einzelne Nadelmodule beim Vorliegen defekter Nadeln ausgetauscht werden und es muss nicht das gesamte Nadelbrett zur Nachrüstung neuer Nadeln ausgebaut werden. Die Nadelmodule können auch verschiebbar im Nadelbrett angeordnet sein und somit lässt sich das Stichbild und die Nadelbrettbestückung variabel gestalten. Außerdem können die Nadelmodule derart eng aneinander angeordnet sein, dass zwischen einzelnen Nadelmodulen kein Zwischenraum verbleibt.In a preferred embodiment, the needles are arranged in needle modules, each needle module having a plurality of needles, and the needle modules being received in recesses or carriers of the at least one needle board and fastened there. The arrangement of the needles in needle modules has several advantages. In this way, individual needle modules can be exchanged if there are defective needles and the entire needle board does not have to be removed to retrofit new needles. The needle modules can also be arranged displaceably in the needle board and thus the stitch pattern and the needle board assembly can be designed variably. In addition, the needle modules can be arranged so close to one another that no space remains between individual needle modules.
In allen Ausführungsformen sind die Drähte vorzugsweise als Metalldrähte, insbesondere Stahldrähte ausgebildet, die bevorzugt nicht rostend sind.In all embodiments, the wires are preferably designed as metal wires, in particular steel wires, which are preferably rustproof.
Die Vernadelungszone erstreckt sich in allen Ausführungsformen in Förderrichtung F vorzugsweise über einen Bereich von 20 cm bis 200 cm, mehr bevorzugt 25 cm bis 80cm.In all embodiments, the needling zone extends in the conveying direction F preferably over a range from 20 cm to 200 cm, more preferably 25 cm to 80 cm.
Die Vernadelungszone erstreckt sich in allen Ausführungsformen quer zur Förderrichtung F vorzugsweise über einen Bereich von 200 cm bis 500 cm, mehr bevorzugt 250 cm bis 400 cm.In all embodiments, the needling zone extends transversely to the conveying direction F, preferably over a range from 200 cm to 500 cm, more preferably 250 cm to 400 cm.
Jedes Nadelmodul kann eine einzelne Längsreihe von Nadeln aufweisen oder mehrere Längsreihen von Nadeln aufweisen.Each needle module can have a single longitudinal row of needles or multiple longitudinal rows of needles.

Um zu vermeiden, dass sich im Flächengebilde 2 Verzüge bilden, während die Nadeln 8 sich im Flächengebilde 2 befinden und dieses weiter in einer Förderrichtung F bewegt wird, kann das Nadelbrett 6 mit den Nadeln 8 in einer bevorzugten Ausführungsform einer Nadelmaschine 1 einen Horizontalhub H parallel zur Förderrichtung F ausführen. Dabei ist das Nadelbrett 6 mit den Nadeln 8 zusammen mit dem textilen Flächengebilde 2 in Förderrichtung F bewegbar. Insbesondere während die Nadeln 8 in das textile Flächengebilde 2 eingestochen sind, werden die Nadeln 8 mit dem Flächengebilde 2 mitbewegt, um eine Relativbewegung zwischen den Nadeln 8 und dem Flächengebilde 2 zu minimieren. Um den Horizontalhub H zu bewirken, kann entweder ein am Nadelbrett 6 angreifender Nebenantrieb vorgesehen sein, oder die Antriebsvorrichtung 14 kann entsprechend ausgebildet bzw. auf eine bestimmte Art mit dem Nadelbalken 4 gekoppelt sein, wie es dem Fachmann bekannt ist.In order to avoid distortions from forming in the
