Description

Verfahren zum nel@@en von Spaltsieben Bei der Herstellung von Spaltsieben aus Längs- und Querdrähten mit schlitzartigen Maschen nach den bekannten Herstellungsverfahren müssen zur Erzeugung der für den Siebvorgang unerläßlichen Maschenfestigkeit die Längsdrähte und auch die Querdrähte im der Teilung des gewollten Maschenabstandes vorgeformt werden. Da derartig vorgeformte Längsdrähte sich nur in kurzen Längen verwenden lassen und- @es nicht möglich ist, solche vorgeformten Stücke auf einen Webstuhl mechanisch zu verweben, ist man gezwungen, das Zus,ammeinfügen der Längs-und Querdrähte von Hand ;oder mit besonderen Maschinen vorzunehmen.Process for nel @@ en wedge wire screens In the manufacture of wedge wire screens from longitudinal and transverse wires with slot-like meshes according to the known manufacturing process must to produce the essential mesh strength for the sieving process Line wires and also the cross wires in the division of the desired mesh spacing be preformed. Since such preformed longitudinal wires are only in short lengths let use and- @it is not possible to put such preformed pieces on one To weave a loom mechanically, one is forced to join the longitudinal and ammein inserting Cross wires by hand or with special machines.

Es ist ,auch bekannt, zur Festlegung der Längs- und Querdrähte an den *Kreuzungsstellen eine Verschweißung vorzunehmen. Dieses Verfahren läßt sich aber nicht bei jedem Werkstoff anwenden, da die Drähte dabei leicht brüchig werden.It is also known to attach the line and cross wires to to weld the * crossing points. This procedure can be but do not use it with every material, as the wires become easily brittle.

Nach der Erfindung wird ,nun so verfahren, daß die Querdrähte glühend gemacht und quer zu den Längsdrähten gelegt werden und daß sodann die Längsdrähte in die glühend gemachten Querdrähte eingepreßt werden. Die glühenden Querdrähte quetschen sich dadurch etwas breit, betten aber die mit ihnen gekreuzten Längsdrähte vollkommen fest ein, so daß eine ähnliche Festigkeit wie bei verschweißten Spaltsleben erreicht wird.According to the invention, the procedure is that the transverse wires are glowing made and placed across the longitudinal wires and that then the longitudinal wires be pressed into the glowing cross wires. The glowing cross wires squeeze themselves a bit wide as a result, but embed the longitudinal wires that cross with them completely tight, so that a similar strength as with welded gap life is achieved.

Es ist auch ein Verfahren bekannt, bei welchem ein teilweises Einpressen von Längsdrähten in Querdrähte erfolgt. Bei diesem müssen aber die letzteren aus weichem Metall hergestellt sein, wodurch die Festigkeit des ganzen Siebes herabgesetzt wird. Bei dem Verfahren nach der Erfindung ist diese unterschiedliche Werkstoffwahl nicht nötig, weil die Längs- und die Querdrähte aus Werkstoff vorn gleichen Eigenschaften gewählt werdet können.There is also known a method in which a partial press fitting from longitudinal wires to transverse wires. In this case, however, the latter must be eliminated be made of soft metal, whereby the strength of the whole screen is reduced will. In the method according to the invention, this is a different choice of material not necessary because the longitudinal and transverse wires made of material have the same properties at the front can be chosen.

Die Zeichnung zeigt beispielsweise die Ausführung des Verfahrens.The drawing shows, for example, the execution of the method.

Die Abb. z zeigt das herzustellende Spaltsieb von der Seite vor dem Einpressen der Längs- in die Querdrähte.Fig. Z shows the wedge wire screen to be produced from the side in front of the Pressing the line wires into the cross wires.

Die Abb.2 zeigt das Spaltsieb von der Seite, nachdem die Längsdrähte b in die glühend gemachten Querdrähte a eingepreßt sind.Fig.2 shows the wedge wire screen from the side after the longitudinal wires b are pressed into the glowing cross wires a.

Die Abb.3 und q zeigen in Draufsicht und Querschnitt in vergrößertem Maßstab, wie sich die Einbettung der Längsdrähte b in die Querdrähte a vollzieht. Die Längsdrähte b werden durch den Druck an den Kreuzungsstellen bei c ein wenig abgeflacht, liegen aber vollkommen fest in den sie kreuzenden Querdrähten a.The Fig.3 and q show in plan view and cross-section in enlarged Scale of how the longitudinal wires b are embedded in the transverse wires a. The longitudinal wires b are slightly due to the pressure at the crossing points at c flattened, but lie completely firmly in the transverse wires crossing them a.
