Definitions

  • the invention relates to a paper machine screen designed as a composite fabric the features of the preamble of claim 1.
  • the so-called Gap or gap formers are clearly implemented in the sheet formation area.
  • the paper machine becomes in the sheet formation area from the headbox exiting jet of paper fiber suspension into the gap between two converging seven pumped and drained over the shortest distance.
  • the screens and drainage elements of the screen section is on one Drainage section between 0.5 and a maximum of 5 m through the headbox freeze the defined formation of the paper sheet and the Increase the dry content of the paper sheet from approx. 0.5% to values around 15%.
  • EP-A-0 010 311 describes a generic paper machine screen in the Training known as composite fabric. This means that in the known solution the upper warp threads that form the binding threads are given to the paper machine screen Properties in relation to drainage that are normally only found in single-layer screens occur. While in other known solutions the binding threads in Fill the sieve volume in open spaces and thus the rapid drainage of the water interfere with the paper web, these open solutions are available in the generic screen solution Rooms for quick drainage are available. Despite this beneficial A possible delamination of the known tissue can be designed due to the high alternating bending loads on the sieve when circulating in the Do not completely exclude the paper machine.
  • the invention is based on the object to further improve a paper machine screen of the generic type so that a unwanted delamination of the tissue is avoided with a high degree of certainty.
  • Warp threads are guided in pairs, there is an advantageous protection of the upper Warp threads while increasing the strength of the connection, so that a Delamination of the fabric due to the high bending stress on the screen in circulation in the paper machine is excluded.
  • the subject of the invention ideally combines the properties of a single-layer screen, which shows very good drainage properties, with a multi-layer sieve that meets the required stability criteria, based on a Composite tissue.
  • a composite tissue Under the well-known mesh construction form the Composite fabrics under the aspect that you can sieves of the same length and Cross thread count compared with comparable thread diameters, the class of Fabrics that have the highest longitudinal and lateral stability.
  • top warps and bottom warps match while the number of top wefts is twice as large the number of lower wefts. But there are other thread densities in the Fabric layers and weaving directions possible.
  • Another advantageous measure for Avoiding disturbances in the drainage characteristics and smoothness of the It is the upper fabric, the upper warp thread at those points on the lower fabric tie, where it is floating on the underside of the upper fabric becomes.
  • a paper machine screen formed as a composite fabric consists of a Upper fabric 1 and a lower fabric 2.
  • the upper fabric 1 has several upper Warp threads 3 in the longitudinal direction of the paper machine screen and several upper ones Weft threads 5 in the transverse direction of the paper machine screen.
  • the warp threads 3 float across several, preferably three wefts 5.
  • the lower fabric 2 consists of several lower weft threads 6 running in the transverse direction of the sieve as well as several lower warp threads running in the longitudinal direction of the sieve 8.
  • the number the upper warp threads 3 corresponds to the number of lower warp threads 8, while twice as many upper wefts 5 as lower wefts 6 are present.
  • the upper wefts 5 are smaller in diameter than the lower wefts 6th
  • the top of the upper fabric 1 forms the sheet formation side of the Paper machine screen, while the bottom of the upper fabric 1 the top of the lower fabric 2 is facing.
  • the underside of the lower fabric 2 in turn forms the running side of the paper machine screen.
  • the lower warp threads 8 are guided in pairs in parallel. At the connection points an upper warp thread 3 to a lower weft thread 6 is one each Pair of lower warp threads 8 in the same direction as the upper warp thread 3 cranked around the lower weft 6.
  • the upper warp thread 3 is between the pair of lower warp threads 8 are pinched. Especially if the Diameter of the upper warp thread 3 is less than the diameter of the lower warp threads 8, the upper warp thread 3 is optimally against this shielded the abrasion on the barrel side.
  • the upper warp threads 3 are arranged in groups so that only every fourth connects the upper warp thread 3 to the lower fabric 2. Part of the mesh of the upper fabric 1 is therefore not by the threads 6, 8 of the lower fabric 2 shaded when viewed vertically.
