Abstract

1. A process for making link belts of synthetic wire material for use with paper making machines, in which wire helices (1, 2) with alternating right-hand and left-hand pitch are laterally slid one into the other whereby closely interlocked crowns of adjacent wire helices (1, 2) form tubular channels (13, 14) into which connecting wires (8) of synthetic material are threaded characterized in that - the connecting wires (8) are thermally fixed prior to being threaded into the channels (13, 14), and - in one operation, one connecting wire (8), each, is threaded into at least two adjacent channels (13, 14).

Description

Gegenstand der Erfindung ist ein Verfahren und eine Vorrichtung zum Herstellen von Drahtgliederbändern, insbesondere zum Einführen von Verbindungsdrähten in die ineinandergreifenden Windungen der Drahtwendelneines Drahtgliederbandes.The invention relates to a method and an apparatus for producing wire link strips, in particular for inserting connecting wires into the interlocking turns of the wire coils of a wire link strip.

Die Erfindung geht aus von Drahtgliederbändern, wie sie in der schweizer Patentschrift CH PS 610 273 beschrieben sind. Per Hand wird eine Wendel nach der anderen in die jeweilige vorher angelegte Wendel mittels Gleitdruck eingepreßt. Werden als Verbindungsmittel der Wendeln Verbindungsdrähte, auch Steckdrähte genannt, verwendet, so werden diese nach jeder eingepreßten Wendel in die röhrenförmige Öffnung,die das jeweils letzte Wendelpaar bildet, von einer Seite her per Hand eingeschoben. Sind die Windungen der Wendel nicht gleichmäßig ausgerichtet, so daß eine gleichmäßige röhrenförmige Öffnung der jeweils korrespondierenden Windungen der Wendeln entsteht, so läßt sich der Verbindungsdraht nicht mehr weiter schieben. Hat eine Wendel eine Fehlstellung eingenommen, so kann sie durch den Verbindungsdraht nicht mehr verschoben werden, da sich die Windungen gegenseitig eng verkrallen und in fester Position halten.The invention is based on wire link belts as described in the Swiss patent CH PS 610 273. By hand, one coil after the other is pressed into the respective previously created spiral by means of sliding pressure. If connecting wires, also called plug-in wires, are used as the connecting means of the coils, these are pushed in by hand from one side after each pressed-in coil into the tubular opening which forms the last pair of coils. If the turns of the helix are not evenly aligned, so that a uniform tubular opening of the respective corresponding turns of the helix is produced, the connecting wire can no longer be pushed. If a helix is misaligned, it can no longer be moved by the connecting wire, since the windings cling to each other and hold in a fixed position.

Es sind für das Anlegen und das Einführen der Verbindungsdrähte mindestens zwei Personen nötig. Das ist sehr zeitaufwendig und bedarf großer Genauigkeit der Arbeiten und Aufmerksamkeit und ist außerdem nur über kleinere Breiten ausführbar, da per Hand der nötige Schiebedruck nicht erreicht wird. Aus diesen Gründen mußte man den Innendurchmesser der Windungskopfbögen größer,' oder den Durchmesser der Verbindungsdrähte kleiner halten, was wiederum den Einsatzzweck und die Lebensdauer beschränkte und auch die Handarbeit weiter erschwerte.At least two people are required to put on and insert the connecting wires. This is very time-consuming and requires great accuracy of work and attention and can also only be carried out over smaller widths, since the necessary pushing pressure is not achieved by hand. For these reasons, the inside diameter of the winding head bends had to be larger, or the diameter of the connecting wires had to be kept smaller, which in turn limited the intended use and the service life and also made the manual work more difficult.

Aufgabe der Erfindung ist es, die genannten Nachteile aufzuheben und ein einfaches Verfahren zu finden Verbindungsdrähte maschinell und wirtschaftlich in Drahtgliederbändern einzuführen. Aufgabe der Erfindung ist es ferner, eine einfache Vorrichtung zur Durchführung des Verfahrengzu finden.The object of the invention is to overcome the disadvantages mentioned and to find a simple method of mechanically and economically inserting connecting wires into wire link belts. The object of the invention is also to find a simple device for performing the method g .

Die Aufgabe wird durch das Verfahren und die Vorrichtung nach den Patentansprüchen gelöst. Mehrere Verbindungsdrähte werden gemeinsam in die röhrenförmigen Öffnungen, welche die ineinandergreifenden Kopfbögen der Wendeln bilden, über die gesamte Breite des Drahtgliederbandes eingeschoben. Durch ein Strecken der verketteten Wendeln kann die enge Verklammerung der Wendeln kurzfristig aufgehoben werden. Dadurch lassen sich schlecht ausgerichtete Wendeln korrigieren und die röhrenförmigen Öffnungs-Kanäle vergleichmässigen, sodaß ein Blockieren der Verbindungsdrähte während des Einschiebens vermieden wird. Durch das Thermofixieren der Verbindungsdrähte vor dem Einschiebevorgang werden diese gerade gerichtet, was sowohl den Einschiebevorgang erleichtert, als auch ein späteres Schrumpfen beim Gebrauch der Siebe vermeidet.The object is achieved by the method and the device according to the patent claims. Several connecting wires are pushed together into the tubular openings, which form the interlocking head arches of the coils, over the entire width of the wire link belt. By stretching the linked coils, the tight clamping of the coils can be released for a short time. As a result, badly aligned spirals can be corrected and the tubular opening channels can be made more uniform, so that blocking of the connecting wires during insertion is avoided. By thermofixing the connecting wires before the insertion process, they are straightened, which both facilitates the insertion process and prevents later shrinkage when using the sieves.

Der technische Vorteil liegt darin, daß sich die Drahtgliederbänder nach der Erfindung rationeller und einfacher herstellen lassen. Durch die Erfindung ist es ferner möglich sehr feine Gliedersiebe mit kleiner Steigung und Teilung auch über große Breiten, zum Beispiel für Papiermaschinen bis zu 10 Metern,herzustellen.The technical advantage is that the wire link belts can be produced more efficiently and easily according to the invention. The invention also makes it possible to produce very fine link sieves with a small pitch and division over large widths, for example for paper machines up to 10 meters.

Ein weiterer Vorteil ist die Einfachheit der Vorrichtung zum Einführen von Verbindungsdrähten.Another advantage is the simplicity of the device for inserting connecting wires.

Connecting wires 8 are inserted in the direction of the arrow to secure the coils.

In Fig.2 ist das Drahtgliederband 1o auf der Ablageunterlage 17 abgelegt und die Einschiebevorrichtung 12 seitlich an einer Kantenseite des Drahtgliederbandes positioniert. Die Klemme 15 erfaßt das Kantenende des Drahtgliederbandes und hält es während des Einschiebevorganges in fester Position. Die Zentriereinrichtung 6 ist auf die Öffnungen 13,14 des Drahtgliederbandes zentriert. Der Walzenantrieb 9 treibt die Verbindungsdrähte über die Zentriereinrichtung durch die Öffnungen 13,14, bis zur anderen Kantenseite des Drahtgliederbandes 1o. Der besseren Übersicht wegen sind die Verbindungsdrähte nur als Einzeldraht 8 gezeichnet. Durch den-Antrieb und die Zentriereinrichtung laufen aber mehrere Verbindungsdrähte gemeinsam. Für einen nächsten Einschiebevorgang wird die Klemme 15,5 geöffnet und ein weiteres Drahtgliederband wird eingelegt. Zur Streckung des Drahtgliederbandes 10, um kurzfristig die enge Verklammerung der Windungen aufzuheben, kann die Einschiebevorrichtung um eine Strecke von der Kante weg in Pfeileichtung verschoben werden.In FIG. 2, the wire link belt 1o is placed on the storage base 17 and the insertion device 12 is positioned laterally on one edge side of the wire link belt. The clamp 15 detects the edge end of the wire link belt and holds it in a fixed position during the insertion process. The centering device 6 is centered on the openings 13, 14 of the wire link belt. The roller drive 9 drives the connecting wires via the centering device through the openings 13, 14 to the other edge side of the wire link belt 10. For a better overview, the connecting wires are only drawn as single wire 8. However, several connecting wires run together through the drive and the centering device. For the next insertion process, terminal 15.5 is opened and another wire link belt is inserted. In order to stretch the wire link belt 10 in order to briefly remove the tight interlocking of the turns, the insertion device can be displaced a distance from the edge in the direction of the arrow.
