Definitions

  • the invention relates to a papermaking wire according to the preamble of claim 1.
  • Pulp suspension refers to a mixture of wood or pulp fibers, fillers, chemical auxiliaries and predominantly water. This filtration process, which is often called sheet formation, takes place in the sheet forming part of the wet end of the paper machine.
  • a fabric or papermaking fabric which meets these requirements as far as possible, is in the DE 100 30 650 C1 described.
  • the object of the present invention is to further improve the known papermachine fabric from its functional properties.
  • a pertinent task solves a papermaking machine with the features of claim 1 in its entirety.
  • the longitudinal threads on the running side within the running side Bindungsrapportes each incorporate two transverse threads of the second type, there is an improved distribution of change or intersection points for the longitudinal threads, so that marks in the paper to be produced are largely avoided.
  • the pertinent integration for the said transverse threads by means of the longitudinal threads is done without these changing between the pairs of embedded transverse threads on the paper side.
  • the claimed shot ratio of the thread system on the paper side to the thread system on the running side leads to a largely self-contained lower or running side with good drainage performance and disturbing operating noise and wear due to increased abrasion of the running side transverse threads is avoided in such a way.
  • the solution according to the invention it is also possible to reduce the transverse threads on the running side in diameter, so that it can not come to the formation of so-called Wasserschleppen; a phenomenon that is caused when the screen after leaving the forming zone by the dewatering elements can not be emptied or insufficient and the residual water is thrown on a deflection roller of the paper machine by the centrifugal forces arising from the tissue.
  • Wasserschleppen a phenomenon that is caused when the screen after leaving the forming zone by the dewatering elements can not be emptied or insufficient and the residual water is thrown on a deflection roller of the paper machine by the centrifugal forces arising from the tissue.
  • the fabric according to the invention is particularly suitable for very fast-moving paper machines and for paper production in the graphic field, which requires very high production qualities.
  • the marking tendency of the upper fabric is preferably further reduced by reducing the number of alternating or crossing points for the longitudinal threads in relation to the number of upper shots used in the form of the transverse threads of the first type or the number of upper shots is increased in the form of transverse threads of the first kind between adjacent warp alternating points. Furthermore, there is the possibility of reducing the tendency to mark when the fabric is being carried out, to further remove the position of the warp change points between two adjacent pairs of warps.
  • slightly thinner running side transverse threads of the second type are introduced within a repeat by the changed shot ratio. This can also reduce the sieve thickness, which reduces the risk of unwanted water drag.
  • the claimed sieve also allows an increase in the permeability and thus the drainage performance at a comparable number of shots on the top or the paper side of the screen, due to the special arrangement of the integration of the running side shots in the form of transverse threads of the second type.
  • FIG. 3 a complete binding repeat of the embodiment according to the invention in the form of Kettverierin or courses of MD threads shown.
  • the cuts of FIGS. 3a to 3h lie along each Kettfadenploes in Fig. 4 starting from the left next to each other.
  • Fig. 3a Incidentally, the illustration corresponds to the Fig. 2 ,
  • Fig. 4 the paper side of the fabric according to the invention is shown.
  • the upper fabric is as in the solution in the prior art according to the Fig. 1 from a plain weave, which is formed alternately by two warp threads (longitudinal threads 41 to 56).
  • the change points under the shots 2, 5, 8, 11, 14, 17, 20 and 23 always two upper shots 1, 3, 4, 6, 7, 9, 10, etc., under which there is never a change.
  • the Fig. 5 further shows the lower fabric in the top view, so a section along the line AA in Fig. 2 .
  • the special design of the Unterschusseinitatien which is designed so that the two outer warp threads of two pairs of warp tie together two sub-shots and in turn two shots are not involved. This ensures that the warp threads located in the lower fabric are pulled under the warp threads located in the upper fabric and thus open areas for a good drainage performance.
  • the warp threads 41 and 42 so far form a pair of longitudinal threads for creating the paper side (see. Fig. 3a ). When the warp thread 41 binds on the running side, the warp thread 42 is on the overlying paper side and vice versa.
  • the adjacent pair of warp threads 43 and 44 fulfills the same task, but seen to the right in the line of sight.
  • the warp thread 41 is always located to the left of the warp thread 42 and the warp thread 43 always left of the warp thread 44.
  • the outer warp threads within these two pairs are then the threads 41 and 44th
