PATENTAMT.PATENT OFFICE.
Die bisher bekannten Feingewebe zum Sieben harter und scharfer Stoffe leiden an zu großer Empfindlichkeit für Verschleiß, Stoß, Zugspannungen usw., die naturgemäß um so größer ist, je feiner das Gewebe des Siebes ist.The previously known fine fabrics for sieving hard and sharp substances suffer from too great sensitivity to wear, shock, tensile stress, etc., which naturally the same is larger, the finer the mesh of the sieve.
Um ein feines, aber doch widerstandsfähiges und nach allen Seiten biegsames Siebgewebe zu erzielen, sind bei vorliegendem Metallsiebe,It's about a fine, but robust and flexible screen mesh on all sides are to be achieved with the present metal sieves,
ίο bei dem in bekannter Weise eine Gruppe von Fäden länglichen Querschnitts mit einer anderen Gruppe von Fäden beliebigen Querschnitts so verflochten ist, daß die breiten Seiten des länglichen Querschnitts senkrecht zur Siebfläche stehen, gemäß der Erfindung die Drähte länglichen Querschnitts möglichst nahe aneinander und unter sich in gleicher Höhe angeordnet, während die Drähte beliebigen Querschnitts jene in senkrecht zur Siebfläche verlaufenden Wellenlinien umschließen. Auf der Zeichnung ist der Erfindungsgegenstand in mehreren Ausführungsformen dargestellt. Dabei sind die Fäden mit länglichem Querschnitt mit a, diejenigen beliebigen Quer-Schnitts mit b bezeichnet.ίο in which in a known manner a group of threads of elongated cross-section is interwoven with another group of threads of any cross-section so that the broad sides of the elongated cross-section are perpendicular to the screen surface, according to the invention, the wires of elongated cross-section as close to each other and below each other arranged at the same height, while the wires of any cross-section enclose those in wavy lines running perpendicular to the screen surface. The subject matter of the invention is shown in several embodiments in the drawing. The threads with an elongated cross-section are denoted by a, and those of any cross-section are denoted by b.
Fig. ι zeigt den Grundriß und Fig. 2 den Schnitt eines Gewebes der gewöhnlichsten Form.Fig. Ι shows the plan and Fig. 2 shows the section of a fabric of the most common Shape.
Fig. 3 stellt ein Gewebe mit gewellten rechteckigen Fäden dar, wie es für Rundsiebe verwendet werden kann, bei denen die größten Zugspannungen in der Peripherie liegen. Die gewellten Fäden mit länglichem Querschnitt gestatten dabei, wie in Fig. 4 und 5 dargestellt ist, das Gewebe auch in ihrer Richtung zu biegen.Fig. 3 shows a fabric with corrugated rectangular threads, as used for round sieves where the greatest tensile stresses are in the periphery. the Corrugated threads with an elongated cross-section allow, as shown in FIGS is to bend the fabric in their direction as well.
Da die Feinheit des vorliegenden Gewebes von der Dicke derjenigen Fäden abhängt, die quer zu den Fäden α länglichen Querschnitts liegen, ist es möglich, wie die Fig. 6 und 7 zeigen, sehr feines und doch widerstandsfähiges Gewebe herzustellen, indem man die Querfäden b gruppenweise zusammenschiebt und durch Schutzhüllen vor Verletzungen bewahrt. Je nach der Beschaffenheit des zu siebenden ,Stoffes wählt man glatte oder gewellte rechteckige Fäden. Die letzteren bilden schon von selbst durch ihre Wellenform Maschen für körnige Stoffe. Es sind noch verschiedene Zusammenstellungen der Fäden möglich, auch kann die Form und die Lage der Wellen der Fäden α den verschiedenen Zwecken entsprechend (z. B. schrägliegend für stehende Siebe) gewählt werden.Since the fineness of the present tissue depends on the thickness of those threads which transversely to the threads α oblong cross-section are, it is possible, as Figs. 6 and 7 show very fine and yet produce high performance fabric by b, the transverse threads in groups pushes together and protected from injuries by protective covers. Depending on the nature of the fabric to be screened, you can choose straight or wavy rectangular threads. The latter form meshes for granular materials by themselves because of their wave shape. There are also various combinations of threads possible, and the shape and position of the waves of the threads α can be selected according to the various purposes (e.g. inclined for vertical sieves).
