Definitions

  • the invention relates to a multilayer, endless drainage sieve according to the preamble of claim 1 and a method for making a multilayer drainage sieve endless according to the preamble of claim 9.
  • a multi-layer drainage screen can be made endless in the same way as a single-layer drainage screen, for example by simply sewing it together with a sewing machine, by means of a fabric connection seam (DE-OS 2 700 390) or a pin seam.
  • a fabric connection seam DE-OS 2 700 390
  • a pin seam Basically, it is also possible to make a multilayer drainage screen endless with a woven seam, as is generally known for single-layer drainage screens.
  • a device for making a single-layer dewatering screen endless is described in DE-AS 1 710205.
  • the binding chain can even be woven in the area of the woven seam. In practice, however, it has been shown that such a multilayer woven seam can hardly ever be produced without defects.
  • the individual layers are preferably stitched at offset locations, which results in a particularly uniform drainage.
  • a particularly preferred embodiment of the invention consists in a multi-layer, in particular two-layer drainage screen, in which each layer is made endless by a woven seam.
  • the drainage sieve according to the invention consists of several layers which are connected to one another by a so-called binding chain. Each layer represents a complete tissue in itself.
  • the individual layers can be in the bin Differentiation type, the size of the repeat and / or the material.
  • the drainage screen contains at least two layers, but can also have three or more layers.
  • the top layer namely the paper-bearing layer, consists of a fabric with a higher number of warp and weft threads per cm and of finer threads.
  • the diameter of the warp threads of a certain layer can differ from the diameter of the weft threads of the same layer.
  • the warp threads of a particular layer do not have to have the same diameter; B. be thicker in the edge area, or thick and thin warp threads can alternate. The same applies to the weft threads of a layer.
  • the top and bottom layer are sewn, e.g. B. the top and bottom layer.
  • the top layer is preferably always sewn, since the paper pulp lies on it.
  • the ends of the non-firmly bonded layers can overlap or butt each other. If the ends of the lowest layer, that is to say the layer which comes into contact with the rollers, are not firmly connected, the ends of this layer preferably overlap.
  • the end of the lowermost layer pointing in the running direction is covered by the other end of the wire and therefore does not come into contact with the rollers.
  • the two ends can be chosen to be of any length. However, the end pointing in the running direction is preferably cut off as short as possible and overlapped by the other end of the screen by a few centimeters or more.
  • the exposed weft threads are drawn into heald frames so that a loom can be formed with the exposed weft threads, into which the warp thread ends projecting like fringes from the fabric ends are inserted.
  • the exposed weft threads are the warp and the fringe-like warp thread ends of the fabric are the weft.
  • the first layer 11 is woven endlessly, the ends of the second layer 12, which is located under the first layer, hanging down.
  • the first layer can then be woven endlessly essentially as described for a single-layer sieve and in connection with FIG. 1.
  • this path can only be followed for screen widths up to approximately 80 cm.
  • the harness cannot be placed next to the sieve.
  • the weaving harness must then be arranged at a correspondingly greater distance from the sieve plane, so that the shaft frames do not touch the already sewn first layer 11 in their lowest position.
  • the binding chain is pulled in single binding and has a diameter of 0.17 mm.
  • the binding chain number is 4.7 / cm.

Claims (10)

1. Tamis d'égouttage sans fin à deux ou plusieurs couches, dans lequel les couches sont associées entre elles par un chaînage de liaison, caractérisé en ce qu'au moins deux couches ou deux groupes de couches comportent des raccordements sans fin séparés, et en ce qu'au moins une couche comporte un raccordement sans fin constitué par une épissure tissée.
2. Tamis suivant la revendication 1, caractérisé en ce que les raccordements des couches ou des groupes de couches sont décalés l'un par rapport à l'autre dans le sens de la longueur du tamis.
3. Tamis suivant la revendication 1, caractérisé en ce que toutes les couches comportent des raccordements séparés, constitués chacun par une épissure tissée.
4. Tamis suivant l'une des revendications 1 à 3, caractérisé en ce que, dans l'épissure tissée de la couche qui porte le papier, les extrémités des brins de chaîne ressortent par la face qui ne reçoit pas le papier.
5. Tamis suivant l'une des revendications 1, 2 ou 4, comportant au moins trois couches, caractérisé en ce que les extrémités d'une couche ou de quelques couches sont disposées bout à bout, sans comporter de raccordement sans fin, les autres couches étant pourvues d'un raccordement sans fin.
6. Tamis suivant l'une des revendications 1, 2, 4 ou 5, caractérisé en ce que la couche située tout en bas n'est pas pourvue d'un raccordement sans fin, et en ce que l'extrémité de cette couche inférieure, orientée dans le sens du mouvement du tamis, recouvre l'autre extrémité de cette même couche inférieure, orientée à l'envers du sens du mouvement du tamis, et se trouve disposée entre cette autre extrémité et les autres couches.
7. Tamis à deux couches suivant la revendication 6, caractérisé en ce que la couche supérieure comporte un raccordement sans fin constitué par une épissure tissée.
8. Procédé pour réaliser le raccordement sans fin d'un tamis d'égouttage sans fin, à deux ou plusieurs couches, conforme à l'une des revendications 1 à 7, caractérisé en ce qu'on assure séparément le raccordement sans fin d'au moins deux couches ou deux groupes de couches, en réalisant une épissure tissée pour le raccordement sans fin de la couche traitée en dernier lieu.
9. Procédé suivant la revendication 8, consistant à confectionner l'épissure tissée au moyen des brins de chaîne-des deux extrémités d'une bande, en enlevant les brins de trame sur une certaine longueur des brins de chaîne pour libérer ceux-ci; puis à fixer par serrage les extrémités de la bande en parallélisme exact avec un écart déterminé, pour entrelacer les brins de chaîne libérés avec des brins de trame, en réalisant des nappes de tissage avec les brins de trame, au moyen d'un appareil de tissage; le procédé étant caractérisé en ce qu'on écarte hors du plan du tamis les brins de trame de la partie déjà constituée de l'épissure de jonction, suivant un angle d'obliquité tel que les brins de trame se trouvent en position basse dans le plan du tamis, ou au-dessus de ce plan.
10. Procédé suivant la revendication 9, caractérisé en ce que l'angle d'écartement des brins de trame hors du plan du tamis est assez grand pour éviter le contact de l'appareil de tissage sur la couche déjà pourvue d'une épissure de jonction, ou sur les autres couches du tamis si celles-ci comportent des épissures décalées.
