Definitions
- the invention relates to a multi-layer, in particular double or three-layer paper machine screen for drainage and leaf formation, according to the preamble of claim 1.
- Such paper machine screens are known for example from EP 432 413. They provide Composite fabrics are and are used in the wet end of paper machines to the over dewater the headbox onto the sieve of fiber suspension and the resulting Feed the paper web to the press section of the paper machine.
- the object of the invention is therefore the tendency to mark paper machine screens by reducing threads on the running side while reducing the Wear volume compared to conventional screens, the interchangeable threads have to increase.
- the lower fabric is interchangeable acting, i.e. alternating wefts alternating from the barrel side to the middle layer is formed, which overlap the warp threads in the exchange area and thereby the chain in front Protect wear, and keep one on the paper side between the fabric layers form additional buffer against marking of the lower tissue.
- the essential idea of the invention is therefore the weft threads on the barrel side a two- or multi-layer paper machine fabric than between the middle layer and the Running side of the fabric interchangeable thread, which makes The lower tissue is buffered so that its tendency to mark with respect to drainage impulses is significantly reduced while the upper fabric is on the lower fabric sort of floats when using two or three layer composite fabric Find.
- the selected form of binding for double-layer fabrics on the running side either the binding chain or on the running side in the case of three-layer fabrics Lower chain are protected from wear by the barrel-side shots.
- a satin or body weave or one of these derived bond find use.
- the double-layer fabric of Fig. 1 shows the structure of the successive running side interchangeable shots.
- This fabric consists of weft threads 1 and warp threads 2, which are integrated into the upper fabric 3 and the lower fabric 4, which through weaving Warp threads are interconnected.
- the weft threads 1 of the lower fabric act interchangeably, i. H. they alternate from the running side A to the middle layer B and thereby overlap in the area of the exchange C.
- Warp threads 2 to protect them from wear and tear that would take place if these warp threads directly with the paper machine, d. H. their drainage and control elements in the area of Sheet formation zone, would come into contact.
- Between two successive areas C is a region D in which the weft threads 1 are exchanged in the middle position and thus between the fabric layers and above those on the running side in this binding phase Warp threads 2 run so that they caused an additional buffer against the lower fabric Form the marking of the paper web.
- the chain which binds through on the running side that is to say, is the chain Warp threads 2 in the exchange area D, arranged so that they under the interchangeable Weft runs through.
- a three-layer fabric according to the invention which is shown in FIG. 2, corresponds in principle to that Features of the double-layer fabric described above in connection with Fig. 1, only that in the case of three-layer fabric, the binding lower chain runs through on the running side due to the selected binding shape the barrel-side shots are protected from wear.

Claims (3)
- Mehrlagiges Papiermaschinensieb zur Entwässerung und Blattbildung, bestehend aus einer oberen und unteren Schußlage oder einem Obergewebe und einem Untergewebe, die übereinander angeordnet und durch Bindefäden miteinander verbunden sind, welche gewebeeigene Fäden sind, die in besonderer Weise in die jeweils andere Gewebelage eingebunden sind, dadurch gekennzeichnet, daß das Untergewebe austauschbar wirkende, d.h. alternierend von der Laufseite zur Mittellage wechselnde Schußfäden (1) aufweist, die im Austauschbereich die Kettfäden (2) überlappen und dadurch die Kette vor Verschleiß schützen, und die auf der Papierseite zwischen den Gewebelagen laufend einen zusätzlichen Puffer gegen Markierung des Untergewebes bilden.
- Mehrlagiges Gewebe nach Anspruch 1, dadurch gekennzeichnet, daß die laufseitig bindenden bzw. durchbindenden Kettfäden (2) im Bereich des Austausches unter dem austauschend verlaufenden Schußfäden (1) hindurchläuft.
- Mehrlagiges Papiermaschinensieb nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß das Untergewebe in Atlas- oder Köperbindung oder einer ihrer Erweiterungen/Ableitungen gefertigt ist.
