Definitions
- the invention relates to a multi-layer screen for the Wet area of a paper machine, in particular for tissue production, with at least two of threads, preferably interwoven threads made by layers with the layers intertwined additional threads are connected and a product made with it.
- the network-like Structure achieved by varying the basis weight, whereby High areas and low areas Basis weight in the macroscopic range alternate.
- the basis weight variation is achieved by varying the drainage capacity of the sieve.
- a variation in the openness of the sieve can also be achieved through the Combine different weaving patterns. It can Basic fabric of the structure-forming sieve, one or more layers, but preferably be two layers. As related to the U.S. Patent 5,219,004 has already been mentioned, it is already known, the layers together by additional threads connect.
- the object of the invention is a multilayer to create a structuring sieve of the type mentioned at the beginning, which makes it easy to produce a improved product the aforementioned modified Adjust drainage properties, and to create such a product.
- This object is achieved in that the additional threads together with the threads forming the layers distributed over the width and length of the sieve Constriction points or zones form due to the significantly less water can drain than through the neighboring zones.
- the additional threads forming constrictions z. B. in Machine direction run and at predetermined places the top of the screen or the layer located there appear and these as narrowing points in Grouping or stringing together in different Directions form constriction areas that pattern over the Area of the sieve appear. These places form in the paper or macroscopic areas in tissue paper Basis weight, d. H. Structures with a lower Deposition of fibers than in the neighboring areas, whereby the elongation behavior in the longitudinal and transverse directions, but particularly advantageously in the transverse direction being affected.
- constriction points to form Length sections at an angle to the machine direction of the screen are lined up, so it is transverse to the machine direction achieved greater flexibility, in addition to Flexibility in the machine direction that the flexibility through Crepe still improved.
- the lengths also alternately in opposite Directions.
- the lengths can but also within the same orientations be arranged in groups running parallel.
- constriction points can be arranged so that closed or at least partially open, but also form continuous courses.
- the arrangement of the Narrowing points should be such that discontinuous courses alone or together with continuous courses available.
- a product according to the present invention is defined in claim 13. Advantageous embodiments of this product can be found in subclaims 14 to 23.
- a paper product made with such a sieve, especially silk or tissue paper, has considerable improved properties especially with regard to so-called haptics or softness. It results in a positive influence on dry and wet strength as well as a positive effect on the crepe process, the drying, the Pressing and drainage.
- the double-layer sieve is designed as a fabric, namely with an upper fabric 10 and a lower fabric 11. Die The machine direction of the sieve is indicated by the arrow A characterized.
- the threads 12a of the upper fabric paper touched side depending on the selected Weaving process designed as warp threads, but also as weft threads be, but preferably as warp threads. same for correspondingly vice versa for the threads 12b of the upper fabric. In in the same way this applies accordingly to the threads 13a or 13b of the lower fabric.
- additional threads 14 run as connecting threads 14 in the same direction and in parallel to the threads 12a such that, as shown in Fig. 1b, the additional threads 14 between the threads 13b and Threads 13c of the lower fabric 11 run and on the from Fig. 1st visible places close stitches 15 by joining them there the top of the upper fabric 10 appear and above Threads 12c of the upper fabric run.
- additional threads 14 constrictions or zones 16 in Machine direction. Oblique to machine direction A strung together, these constrictions 16 result in Longitudinal sections formed constriction areas 17. Rein two in one direction are exemplary parallel constriction areas 17 and 18 are provided. Alternating such constriction areas are in z. B.
- FIGS. 2 to 5 show a structure with different designs.
- Fig. 2 shows a product with a Sieve structure according to FIG. 1 was generated. Thereby form the the areas marked in dark the aforementioned network-like structure. This creates a coherent Zone of high basis weight formed. The same applies 3, 4 and 5.
