Definitions
- the invention relates to a forming fabric according to the preamble of patent claim 1.
- Forming fabrics are used in the forming section of a paper machine. At the Forming process is a fiber suspension from the headbox of the paper machine on a Forming screen or on two Formiersiebe (Gap - formers) applied. It is the Task of forming fabrics to dewater the fiber suspension and a fibrous web in the dewatering process as little as possible pulp fibers and Fillers from the fiber suspension to be washed out.
- the quality of the fibrous web formed is greatly influenced by the structure of the Determined fibrous web facing surface (paper side) of the forming fabric.
- the Life of the forming fabric is strongly dependent on the structure of the Paper machine facing surface (machine side) of the forming fabric influenced.
- the stitching threads are preferably an integral part of Paper-side weave structure (integral stitching threads), which causes marking tendencies be reduced by the connection of the stitching threads.
- each first and every second binding region is formed by, in the the first and second stitching threads each under at least two and at most three running to each other adjacent lower machine direction threads.
- the binding area in this case the area bounded by the stitching thread of the machine-side weave structure defining one or more lower MD threads span.
- the stitching thread on one side of the paper side Web structure fed to the MD thread then runs under this MD thread and then becomes then led away again from the MD thread to the paper-side weave structure. Of the Bonding area is thus spanned by a lower MD thread.
- the invention is based on the consideration that the connection of the paper side Web structure on the machine-side weave structure in a forming fabric with integral Stapling threads can be improved by applying a stitching thread to the machine-side woven structure and applied in the direction of the machine side Weave structure acting force from a lower (machine side) Machine direction thread (MD thread) on at least two maximum but three lower MD threads is split. That According to the invention is a bond area with two to three lower MD threads.
- a binding region according to the invention is formed by the fact that the Stitching thread runs under all the MD threads of the binding area, thus, in contrast to the case in which the stitching thread in the binding area over one or more lower MD threads would run, the sieve of the invention can be kept thinner.
- a preferred embodiment of the invention therefore provides that between a first and a second binding area a maximum of three lower machine direction threads are arranged.
- the first stitching thread of a pair weaves with a number of upper machine direction threads first segments. Furthermore, the second stitching thread weaves The pair weaves second with a number of other top machine direction threads Segments, wherein the first and second segments in the cross-machine direction are arranged alternately lying one behind the other.
- the segment of the paper-side area woven by a stitching thread is intended to be the segment Web structure defined by one or more top MD threads.
- the stitching thread is from the machine side weave structure fed on one side to the top MD thread, then runs over that top MD thread and then from the top MD thread to the machine side Web structure led away again.
- the segment is characterized by an upper MD thread clamped.
- top MD threads delimit two top MD threads the segment; a first upper MD thread, which the stitching thread from the machine side Web structure is fed and runs over the stitching thread and a second upper MD thread over which the stitching thread runs and of which the stitching thread again the machine-side weave structure is fed, wherein between these two upper MD threads the stitching thread neither goes to the machine-side weave structure nor from this comes.
- the first and the second segments are used by the the upper MD yarns and the upper CMD yarns (CD yarns) educated web structure continued.
- the marking tendency and the planarity of the paper-based web structure has the direct influence of the size of the segments. If the segments are too small form "hard” binding sites with too large Marking tendency. If the segments are too big, the paper-side weave may be bulge in the area of the segments, with the result that the planarity of the paper side Web structure is unsatisfactory. Research has shown that one particular smooth paper-side surface is created when every first and every second Segment each with at least two and a maximum of five mutually adjacent upper Machine direction threads is formed.
- each first and every second transitional area should each have a maximum three mutually adjacent pairs of upper and lower MD threads is formed. This steep connection makes the paper side and the machine side Web structure closer together. By the more intimate connection between the Both weave structures are also the so - called "Edge - Curl - Effect" (bulging of the Edge areas of the screen) reduced.
- planarity of the paper-based web structure can be further improved in this way the first stitching thread of a pair per repeat unit of the weave structure in Cross machine direction runs over and under the same number of upper machine direction threads like the second stitching thread.
- a preferred embodiment of The invention therefore provides that per repeating unit of the web structure in Cross machine direction, the first and the second stitching threads of each pair the same Walk under, over, and between the top and bottom machine direction threads.
- this is the paper-side weave structure of the forming fabric according to the invention designed as a plain weave pattern.
- a preferred embodiment of the invention provides that the first and the second Segments each with three adjacent upper machine direction threads, the first and the second transition regions each with a maximum of two to each other adjacent pairs of upper and lower machine direction threads and the first and the second binding regions each having two lower adjacent ones Machine direction threads are formed.
- the forming fabric according to the invention are different Relationships between upper and lower cross machine direction yarns possible.
- a preferred embodiment of the invention provides that between two to each other adjacent pairs of first and second stitching threads two lower ones Cross-machine direction yarns and an upper cross-machine direction yarn are arranged are. This ratio corresponds to a CD thread ratio of 1: 1.
- a further embodiment of the invention provides that between two to each other adjacent pairs of first and second stitching threads a lower one Cross-machine direction yarn and an upper cross-machine direction yarn arranged is. This ratio corresponds to a CD thread ratio of 2: 1.
- a preferred embodiment of The invention therefore provides that each of the lower cross machine direction yarns respectively over one and then under at least seven adjacent ones Machine direction threads are running. 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 a smaller thickness of the screen makes possible and on the other hand a smaller Drainage resistance can result.
- a further preferred embodiment of the invention provides that at least two Pairs of first and second stitching threads disposed immediately adjacent to each other are. Generally, increasing the number of twine pairs increases the number of tethers increases, thereby improving the connection of the upper weave structure to the lower Web structure and a higher stiffness of the forming fabric is achieved.
- each pair of first and second stitching threads between at least two upper ones Cross-machine direction yarns are arranged.
- a preferred embodiment of the invention provides that at least one Pair of stitching threads is provided, in which between the first stitching thread and the second stitching thread of the pair is arranged a lower cross-machine direction yarn.
- a further preferred embodiment of the invention provides that at least one pair of stitching threads is provided, wherein the first and second stitching thread between at least two lower cross machine direction yarns is arranged.
- a lower attachment point which formed by a lower cross-machine direction yarn under a first lower machine direction yarn and over a second lower adjacent thereto Machine direction yarn runs, the second lower machine direction yarn immediately adjacent to a lower machine direction thread of a first or second binding region is arranged.
- a further preferred embodiment of the invention provides that the second lower Machine direction yarn, a lower machine direction yarn of the first or second Binding area is.
