Definitions

  • the invention relates to a forming fabric according to the preamble of patent claim 1.
  • Forming screens are used in the forming section of a paper machine.
  • a fiber suspension is applied from the headbox of the paper machine to a forming fabric or to two forming fabrics (Gap formers). It is the task of forming fabrics to dewater the fiber suspension and to form a fibrous web, with as little pulp fibers and fillers as possible being washed out of the fiber suspension during the dewatering process.
  • the quality of the fibrous web formed is strongly influenced by the structure of the fibrous web-facing surface (paper side) of the forming fabric.
  • the life of the forming fabric is greatly affected by the structure of the paper machine facing surface (machine side) of the forming fabric.
  • multi-ply papermachine screens have been developed with a paper-side and a machine-side fabric, wherein the two independent fabrics are connected to each other by so-called stitching or binding threads.
  • stitching threads are an integral part of the paper-side weave structure (integral stitching threads), as a result of which marking tendencies due to the binding of the stitching threads are reduced.
  • each first and each second binding region is formed by running the first and second stitching yarns under at least two and at most three mutually adjacent lower machine direction yarns.
  • the paper-side weave structure and the machine-side weave structure are connected by the stitching thread (s) in which the stitching thread (s) coming from the paper-side weave structure are repeatedly formed under a lower, for example, machine direction yarn to create a weave area and subsequently woven again with threads from the paper-based weave structure.
  • the region of the machine-side weave structure, which is bound by the stitching thread is to be defined as the binding region, which span one or more lower MD threads.
  • the stitching thread on one side of the paper-side weave structure is fed to the MD thread, then passes under this MD thread and is then subsequently led away from the MD thread to the paper-side weave structure again.
  • the binding area is thus spanned by a lower MD thread.
  • two lower MD threads define the binding area; a first lower MD thread to which the stitching thread is fed from the paper side weave structure and under which the stitching thread runs, and a second lower MD thread under which the stitching thread runs and from which the stitching thread is fed back to the paper side weave structure, between them both lower MD threads of the stitching thread neither runs to the paper-side weave structure nor comes from this.
  • the force of the stitching thread acting in the direction of the paper-side weaving structure can not be transmitted due to the deflection of the "suspended" lower machine direction thread.
  • the invention is based on the consideration that the connection of the paper-side woven structure to the machine-side weave structure can be improved in a forming fabric with integral stitching threads by the force exerted by a stitching thread on the machine-side weave structure and acting in the direction of the machine-side weave structure from a lower (Machine-side) machine direction yarn (MD yarn) is divided on at least two maximum but three lower MD yarns. That According to the invention, it is a binding region with two to three lower MD threads.
  • these hinged lower MD yarns Due to the distribution of force from one to two or three lower MD yarns, these hinged lower MD yarns have a significantly smaller deflection than a single hinged lower MD yarn, thereby increasing the paper-side weave structure to the entire machine-side weave structure can be transmitted, so that the connection of the paper-side weaving structure is improved to the machine-side weaving structure. As a result, the forming fabric becomes thinner and more compact.
  • a binding portion is formed by passing the stitching thread under all the MD threads of the binding portion, whereby, contrary to the case where the stitching thread in the binding portion runs over one or more lower MD threads, the screen of the present invention is thinned can.
  • the first stitching thread or the second stitching thread runs under at least two and at most three mutually adjacent lower machine direction threads.
  • a preferred embodiment of the invention therefore provides that a maximum of three lower machine direction threads are arranged between a first and a second binding region.
  • the first stitching thread of a pair having a number of upper machine direction threads weaves first segments. Further, the pair's second stitching thread weaves second segments with a number of other top MD yarns, with the first and second segments arranged alternately one behind the other in the cross-machine direction.
  • the segment of the paper-side weave structure woven by a stitching thread should be defined as the segment, which span one or more upper MD threads.
  • the stitching thread is fed from the machine-side weave structure on one side to the upper MD thread, then passes over this upper MD thread and is then subsequently led away from the upper MD thread to the machine-side weave structure.
  • the segment is clamped by an upper MD thread.
  • two upper MD yarns delimit the segment; a first upper MD thread to which the stitching thread is fed from the machine side weave structure and over which the stitching thread runs and a second upper MD thread over which the stitching thread passes and from which the stitching thread is returned to the machine side weave structure, between these two Upper MD threads of the stitching thread neither to the machine-side weave structure still comes from this.
  • the weave structure formed by the upper MD threads and the upper cross-machine direction threads is continued by the first and the second segments.
  • the size of the segments has a direct influence on the marking tendency and the planarity of the paper-based web structure. If the segments are too small form "hard” binding sites with too much marking tendency. If the segments are too large, the paper-side weave structure may bulge around the segments, with the result that the planarity of the paper-side weave structure becomes unsatisfactory. Investigations have shown that a particularly smooth paper-side surface is created when each first and every second segment is formed with at least two and at most five mutually adjacent upper machine direction threads.
  • each first segment and the first binding region or between each second segment and the second binding region respectively a first and second transition region, in which the first and second stitching thread runs between mutually adjacent pairs of upper and lower machine direction threads, respectively.
  • a preferred embodiment therefore provides that each first and each second transition region is formed in each case with a maximum of three mutually adjacent pairs of upper and lower MD threads. This steep connection binds the paper-side and machine-side weave closer together. The more intimate connection between the two weave structures also reduces the so-called "edge-curl effect" (bulging of the edge areas of the screen).
  • the planarity of the paper-side weave structure can be further improved by running the first stitching thread of one pair per unit of repeat of the cross-machine direction weave structure above and below as many upper machine direction threads as the second stitching thread.
  • both stitching threads of each pair traverse the same path in the cross-machine direction during weaving with the upper and lower machine direction threads.
  • a preferred embodiment of the invention therefore provides that, per repeat unit of the cross-machine direction web structure, the first and second stitching yarns of each pair travel the same path under, over and between the upper and lower machine direction yarns.
  • the paper-side weave structure of the forming fabric according to the invention is formed as a plain weave pattern.
  • a preferred embodiment of the invention provides that the first and the second segments each having three adjacent upper machine direction yarns, the first and the second transition regions each having a maximum of two mutually adjacent pairs of upper and lower machine direction yarns and the first and the second bonding regions each with two mutually adjacent lower machine direction threads are formed.
  • a preferred embodiment of the invention provides that between two mutually adjacent pairs of first and second stitching threads, two lower cross machine direction yarns and one upper cross machine direction yarn are arranged. This ratio corresponds to a CD thread ratio of 1: 1.
  • two lower transverse machine direction threads and two upper cross machine direction threads are arranged between two mutually adjacent pairs of first and second stitching threads.
  • This ratio corresponds to a CD thread ratio of 3: 2.
  • a further embodiment of the invention provides that a lower transverse machine direction yarn and an upper transverse machine direction yarn are arranged between two mutually adjacent pairs of first and second tacking yarns. This ratio corresponds to a CD thread ratio of 2: 1.
  • each of the lower CMD yarns passes over one and then under at least seven machine direction yarns adjacent each other.
  • Another advantage of the so-called long floating is that the proportion of lower CD threads within the screen is reduced, which on the one hand makes a smaller thickness of the screen possible and on the other hand can result in lower drainage resistance.
  • a further preferred embodiment of the invention provides that at least two pairs of first and second stitching threads are arranged directly adjacent to each other. Generally, by increasing the pairs of twine, the number of tethers is increased, thereby achieving a better bonding of the upper weave structure to the lower weave structure and a higher stiffness of the forming fabric.
  • each pair of first and second stitching threads are arranged between at least two upper CMD yarns.
  • first and second stitching yarns of a pair of stitching yarns may be disposed relative to the bottom CMD yarns.
  • a preferred embodiment of the invention provides that at least one pair of stitching threads is provided in which a lower cross machine direction yarn is arranged between the first stitching thread and the second stitching thread of the pair.
  • a further preferred embodiment of the invention provides that at least one pair of stitching threads is provided in which the first and second stitching threads are arranged between at least two bottom CMD threads.
  • a lower tying site formed by passing a lower cross machine direction yarn below a first lower machine direction yarn and over a second lower machine direction yarn adjacent thereto, the second lower machine direction yarn immediately adjacent a lower machine direction yarn of a first machine direction yarn second binding region is arranged.
  • the second lower machine direction thread is a lower machine direction thread of the first or second binding area.
