Abstract
Description
Die Erfindung betrifft eine Tuftingmaschine mit mindestens einer eine Reihe von Tuftingnadeln tragenden Nadelbarre sowie ein Nadelmodul, das eine Reihe von Tuftingnadeln hat und an der Barre einer Tuftingmaschine festlegbar ist.The invention relates to a tufting machine with at least one of a series of tufting needles load-bearing needle bar and a needle module that has a number of tufting needles and on the Barre a tufting machine can be determined.
Bei bekannten Maschinen dieser Art sind die Tuftingnadeln jeweils auf einer durchgehenden Geraden in einer Reihe angeordnet (siehe DE-C-19 528 152). Das Grundgewebe wird jeweils um den Stichabstand bezüglich der Reihe der Tuftingnadeln vorgerückt. Es ist auch bekannt, zwei derartige Reihen von Tuftingnadeln gleichzeitig an einer Nadelbarre festzulegen, so daß bei einer Bewegung der Nadelbarre zwei Einstichreihen entstehen (siehe US-A-3 641 956).In known machines of this type, the tufting needles are in each case continuous Straight lines arranged in a row (see DE-C-19 528 152). The base fabric is each related to the stitch spacing the row of tufting needles. It is also known to have two such rows of Set tufting needles at the same time on a needle bar so that when the needle bar moves two rows of punctures arise (see US-A-3 641 956).
Es hat sich nun gezeigt, daß insbesondere bei niedrigpoligen Teppichen sich dann Querrippen im Fertigprodukt bilden, wenn mit einem relativ großen Stichabstand, z.B. >3,5 mm, gearbeitet wird. Diese Querrippen stellen eine unerwünschte, störende Musterung des Teppichs dar.It has now been shown that, particularly in the case of low-pile carpets, transverse ribs in the Form the finished product if with a relatively large stitch spacing, e.g. > 3.5 mm, worked becomes. These cross ribs represent an undesirable, annoying pattern on the carpet.
Die Aufgabe der vorliegenden Erfindung liegt nun darin, diese störende Musterung mit einfachen apparativen Mitteln zu beseitigen.The object of the present invention is to eliminate this disruptive pattern with simple to eliminate equipment.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, eine Tuftingmaschine der eingangs genannten Art so auszubilden, daß in jeder Reihe - oder bei Einsatz mehrerer Reihen zumindest in jeder zweiten Reihe - die Tuftingnadeln quer zur Barrenachse unterschiedlich weit parallel versetzt sind, wobei der Versatz der Tuftingnadeln innerhalb einer Reihe maximal der Hälfte des Stichabstandes in Tuftrichtung entspricht. Der Versatz kann dabei den jeweiligen Erfordernissen angepaßt werden.To solve this problem, the invention provides a tufting machine at the outset mentioned type so that in each row - or at least when using several rows in every second row - the tufting needles at different distances parallel to the bar axis are offset, the offset of the tufting needles within a row at most half of the Stitch distance in the tuft direction corresponds. The offset can meet the respective requirements be adjusted.
In vielen Fällen wird es zweckmäßig sein, die erfindungsgemäße Tuftingmaschine so auszubilden, daß der Versatz der Tuftingnadeln innerhalb einer Reihe mindestens einem Zehntel des Stichabstandes in Tuftrichtung entspricht.In many cases it will be expedient to design the tufting machine according to the invention that the offset of the tufting needles within a row is at least one tenth of the Stitch distance in the tuft direction corresponds.
Als besonders vorteilhaft hat sich eine Tuftingmaschine gezeigt, die sich dadurch auszeichnet, daß der Versatz (S) der Tuftingnadeln in einer Reihe bestimmt ist aus dem Quotienten 50 : (Stichzahl/dm). Dabei kommt es zu einer völlig gleichmäßigen Verteilung der Einstichnoppen und damit zu einem sicheren Ausschluß von unerwünschten Querrippen. A tufting machine, which is distinguished by the fact that that the offset (S) of the tufting needles in a row is determined from the quotient 50: (Stitch number / dm). This results in a completely even distribution of the puncture knobs and thus a safe exclusion of unwanted cross ribs.
Die erfindungsgemäße Tuftingmaschine kann so ausgebildet sein, daß die Tuftingnadeln einer Reihe jeweils in gleichem Maße und alternierend versetzt angeordnet sind.The tufting machine according to the invention can be designed so that the tufting needles one Row are arranged to the same extent and alternately offset.
Erfindungsgemäß wird ferner vorgeschlagen, daß bei einer Tuftingmaschine die eine Reihe von Tuftingnadeln tragende Nadelbarre aus zwei parallel zueinander verlaufenden, jeweils parallel zueinander verlaufende Tuftingnadeln tragenden Barrenabschnitten gebildet ist, von denen zumindest einer in seinem Abstand zum anderen variabel einstellbar ist, um den Versatz der Tuftingnadeln innerhalb der Reihe zu wählen. Somit kann der Versatz der Nadeln einer Reihe für jeden Tuftvorgang gezielt eingestellt werden.According to the invention it is further proposed that in a tufting machine a number of Needle bar carrying tufting needles consisting of two parallel to each other, each parallel ingot sections carrying mutually extending tufting needles are formed, at least of which one is variably adjustable in its distance from the other to the offset of the tufting needles to choose within the series. Thus, the offset of the needles in a row for each tufting can be set specifically.
Dabei kann erfindungsgemäß weiter vorgesehen sein, daß zumindest bei den in einem der Barrenabschnitte sitzenden Tuftingnadeln der Schaft gegenüber dem Kolben in Richtung auf den anderen Barrenabschnitt abgekröpft ist.It can further be provided according to the invention that at least in one of the bar sections seated tufting needles the shaft opposite the piston towards the other bar section is bent.
Die Erfindung sieht für die Lösung der gestellten Aufgabe ein Nadelmodul vor, das sich dadurch auszeichnet, daß die Tuftingnadeln quer zu der Reihe unterschiedlich weit versetzt sind, wobei der Versatz der Tuftingnadeln innerhalb der Reihe maximal der Hälfte des Stichabstandes in Tuftrichtung entspricht. Unter Verwendung derartiger Module können dann Nadelreihen erzeugt werden, wie sie auch durch unmittelbares Festlegen der Nadeln an der Barre gebildet werden können.The invention provides for the solution of the task, a needle module, which is thereby is distinguished by the fact that the tufting needles are offset at different distances across the row, whereby the offset of the tufting needles within the row is a maximum of half the stitch spacing in Tuft direction corresponds. Using such modules, rows of needles can then be generated be as they are formed by directly setting the needles on the bar can.

Figur 1 zeigt ein Modul mit einem Modulkörper 1, der eine Reihe von in einer geraden Linie fluchtend angeordneten Tuftingnadeln 2 trägt. Diese Module sind an einer nicht dargestellten Nadelbarre festgelegt und bilden auf diese Weise eine auf einer Geraden liegende Nadelreihe. Daraus folgt das in Figur 1 dargestellte Einstichbild mit dem Stichabstand S1. Wird der Tuftingvorgang niedrigpolig und mit relativ großem Stichabstand durchgeführt, so ergibt sich ein Oberflächenbild mit störenden Querrippen zwischen den geradlinigen Reihen der Einstichstellen.Figure 1 shows a module with a module body 1, which is a series of in a straight line aligned tufting needles 2 carries. These modules are on one, not shown Needle bar fixed and in this way form a row of needles lying on a straight line. The puncture pattern shown in FIG. 1 with the stitch spacing S1 follows from this. The tufting process With a low pole and a relatively large stitch spacing, this results in a surface image with annoying cross ribs between the straight rows of puncture points.
Figur 2 zeigt ein Modul für den erfindungsgemäßen Aufbau einer Tuftingmaschine. Hier sind in
einem Modulkörper 3 wieder mehrere Tuftingnadeln 4 angebracht, die aber in Längsrichtung des
Moduls und damit in Längsrichtung der nicht dargestellten Nadelbarre quer zur Barre und damit
auch quer zum Modulkörper um das Maß S2 versetzt sind. Ein Tuftingvorgang führt dabei jeweils
zu einem Einstichbild, wie es zwischen den Linien 5 dargestellt ist. Es kommt auf diese
Weise zu einer gleichmäßigen Verteilung der Einstichstellen und gleichzeitig zu einer Verringerung
des Abstandes zwischen den Einstichstellen in der Tuftrichtung gemäß Pfeil 6. Der Versatz
der Tuftingnadeln 4 einer Reihe kann den jeweiligen Gegebenheiten angepaßt sein. Einen besonders
guten Effekt erreicht man dann, wenn der Versatz der Tuftingnadeln (4) in einer Reihe bestimmt
ist aus dem Quotienten 50 : (Stichzahl/dm).Figure 2 shows a module for the construction of a tufting machine according to the invention. Here are in
a module body 3 again attached
Die erfindungsgemäße Anordnung ist insbesondere für die Herstellung niedrigpoliger Ware geeignet, also bei einer Polhöhe < 3,5 mm.The arrangement according to the invention is particularly suitable for the production of low-pole goods, in other words with a pole height <3.5 mm.
Im beschriebenen Beispiel wird von der Verwendung von Modulen ausgegangen, mit denen an einer Nadelbarre eine durchgehende Nadelreihe gebildet werden kann. Der gleiche Effekt läßt sich selbstverständlich auch dann erzielen, wenn die Tuftingnadeln unmittelbar in einer Nadelbarre eingesetzt und an dieser fixiert sind.The example described assumes the use of modules with which a continuous row of needles can be formed on a needle bar. The same effect leaves can of course also be achieved if the tufting needles are directly in a needle bar used and fixed to this.
Es ist überdies möglich, sowohl unter Verwendung von Modulen als auch bei unmittelbarer Befestigung an der Barre zwei oder mehr Nadelreihen vorzusehen. Dabei kann der gewünschte Effekt schon dadurch herbeigeführt werden, daß die Tuftingnadeln jeder zweiten Reihe in der beschriebenen Weise versetzt angeordnet sind.It is also possible to use modules as well as with direct attachment provide two or more rows of needles on the bar. It can have the desired effect can be brought about by the fact that the tufting needles of every second row in the described Are arranged offset.
