Definitions
- Multi-layer screen for the wet area of a paper machine and the product made with it
- the invention relates to a multi-layer sieve for the wet area of a paper machine, in particular for tissue production, with at least two layers made from threads, preferably woven threads, which are connected to each other by additional threads intertwined with the layers and a product produced therewith.
- silk or tissue paper with a network-like structure in which the normally flat, homogeneous, normally inflexible structure of the dried silk or tissue paper due to the differences in basis weight generated in the sheet formation in the macroscopic area in a flat, inhomogeneous, network-like structure is transferred, which reacts flexibly when subjected to external forces.
- the creping process which is usually carried out in the manufacture of tissue paper makes the tissue paper more flexible compared to the stresses caused by external forces, but predominantly in the machine direction.
- the higher flexibility in the machine direction that can be achieved with creping in the case of a homogeneous paper structure manifests itself in an increased working capacity with the result of greater flexibility in the machine direction.
- the flexibility of the paper and thus also of a silk or tissue paper can be additionally improved, whereby this improvement is not limited to the machine direction, but can also be achieved in the cross machine direction .
- the network-like structure is achieved by varying the basis weight, areas of high basis weight and areas of low basis weight in the macroscopic range being one another alternate.
- the variation in the basis weight is achieved by varying the drainage capacity of the sieve.
- the openness of the sieve can also be varied by combining different weaving patterns.
- the base fabric of the structure-forming sieve can have one or more layers, but preferably two layers. As has already been mentioned in connection with US Pat. No. 5,219,004, it is already known to connect the layers to one another by means of additional threads.
- the additional threads together with the threads forming the layers form narrowing points distributed over the width and length of the sieve, through which significantly less water can flow off than through the adjacent areas.
- This solution is characterized in that the additional threads used for connecting the layers of the sieve are used to form the closed zones or essentially closed zones of the sieve, the essentially open zones being formed in the regions of the sieve, where the additional threads do not close the stitches in the base fabric.
- a double function is achieved with the additional threads.
- Such a sieve can be used to produce a significantly improved paper product, in particular silk or tissue paper.
- the additional threads can form constriction z. B. run in the machine direction and appear at predetermined locations on the top of the screen or the location there and these as constriction points in
- constriction points for the formation of longitudinal sections can also be strung together to some extent perpendicular to the machine direction and partially in the machine direction.
- the longitudinal sections can also be aligned alternately in opposite directions.
- the longitudinal sections can also be arranged in parallel within the same orientations in groups.
- constriction points can be strung together to form zigzag or wavy courses.
- constriction points can be arranged so that closed or at least partially open, but also continuous courses are formed.
- the arrangement of the constriction points can also be such that discontinuous courses are available alone or together with continuous courses.
- a paper product produced with such a sieve, in particular silk or tissue paper, has considerably improved properties, in particular with regard to the so-called feel or softness.
- Figure 1 is a plan view of a multi-layer sieve according to the invention.
- Figure la is a sectional view through the screen of Figure 1 along the section line a-a.
- FIG. 1b shows a sectional view through the sieve according to FIG. 1 along the section line b-b;
- 6 to 12 are schematic representations of further multi-layer sieves with different configurations of the layer arrangement of additional threads as connecting threads;
- FIG. 13a shows a conventional flat, homogeneous tissue paper before and after applying a stretching force (arrows);
- FIG. 13b shows a flat, inhomogeneous, network-like tissue paper according to the invention, also before and after applying a stretching force (arrows).
- the double-layer sieve is designed as a fabric, with an upper fabric 10 and a lower fabric 11.
- the machine direction of the screen is indicated by the arrow A.
- the threads 12a of the upper fabric paper-touched side
- the threads 12b of the upper fabric can be designed as warp threads, but also as weft threads, but preferably as warp threads. same for correspondingly vice versa for the threads 12b of the upper fabric. In the same way, this applies accordingly to the threads 13a and 13b of the lower fabric.
- additional threads 14 run as connecting threads 14 in the same direction and parallel to the threads 12a in such a way that, as shown in FIG. 1b, the additional threads 14 run between the threads 13b and threads 13c of the lower fabric 11 and on the thread from FIG 1 visible places close stitches 15 by appearing there on the upper side of the upper fabric 10 and running above threads 12c of the upper fabric.
- the additional threads 14 form constriction points 16 in the machine running direction. Lined up obliquely to the machine direction A, these constriction points 16 result in constriction regions 17 designed as longitudinal sections. Purely by way of example, two parallel constriction regions 17 and 18 are provided in each direction. Alternating such constriction areas are in z. B.
- FIG. 2 shows a product that was produced with a sieve structure according to FIG. 1. The areas marked in dark form the aforementioned network-like structure. This creates a coherent zone of high basis weight. The same applies to the product according to FIGS. 3, 4 and 5.
- FIGS. 3 shows a product that was produced with a sieve structure according to FIG. 1. The areas marked in dark form the aforementioned network-like structure. This creates a coherent zone of high basis weight. The same applies to the product according to FIGS. 3, 4 and 5.
- the dark areas, which mean high weight, can also be those with low weight and which are light represented area parts, which mean low basis weight, correspondingly be those with high basis weight (see the example of FIGS. 2a, 3a). Then the brightly colored areas form the aforementioned network-like structure.
- FIGS. 6 to 8 Further modifications of the sieve structure can be seen schematically in FIGS. 6 to 8.
- the parts by area having a low basis weight form the aforementioned network-like structure.
