Definitions

  • the invention relates to a paper machine clothing, especially as a dryer fabric, with one for the pad a paper web provided and one of them machine side facing away, the paper machine clothing has a fabric of longitudinal and transverse threads or consists of and with two adjacent longitudinal threads tied to form a pair of longitudinal threads tie with cross threads.
  • Such a dryer fabric can be found in EP-A-0 837 179 or EP 0 609 664 A1.
  • the dryer fabric known from EP 0 609 664 A1 consists of a single-layer fabric with round Cross threads, which are also designed as hollow monofilaments can be, and with two longitudinal thread systems, the Longitudinal threads are designed as flat monofilaments.
  • One the longitudinal thread systems run primarily on the paper side, with two adjacent longitudinal threads Longitudinal thread pair forms, which is identical to the transverse threads integrates.
  • the second longitudinal thread system runs in each case a longitudinal thread below a pair of longitudinal threads.
  • the longitudinal threads are often used to form the loops of the paper machine fabric by a Part of the longitudinal threads passed beyond the last cross thread and forming an eyelet back into the tissue is woven back while another part of the longitudinal threads immediately, i.e. woven back without eyelets (see US 5,089,324; US 4,438,789).
  • the weaving back happens to those disclosed in these documents Weave in such a way that the woven part of the respective longitudinal thread next to this is involved, wherein the course of this section from that of the one in question Longitudinal thread deviates.
  • the paper machine fabric according to EP 0 532 510 B1 the woven back section below the associated longitudinal thread back into the tissue introduced so that the loops do not twist subject.
  • the invention has for its object the front edges with a paper machine clothing of the aforementioned To form a kind for the purpose of producing a plug-in seam, that the product image especially on the paper side over the entire length of the paper machine clothing is constant.
  • This object is achieved in that the front edges of the paper machine clothing Longitudinal thread of a longitudinal thread pair with the neighboring one Longitudinal thread of the adjacent pair of longitudinal threads a loop forms.
  • the basic idea of the invention is therefore that Longitudinal thread formation of the loops so that the adjacent by a loop of longitudinal threads run, but to two different neighboring ones Longitudinal thread pairs belong.
  • This type of longitudinal thread guide guarantees an even product image on the paper side over the entire length of the paper machine clothing, loops for a plug-in wire seam being formed at the same time become.
  • the properties of paper machine clothing are therefore over the entire length by the embossed in pairs guiding the longitudinal threads.
  • Cross threads on the machine side of at least one Part of transverse threads designed as flat transverse threads are in contact and each a flat cross thread and its attached to it adjacent transverse threads of at least part of the Longitudinal threads are integrated together.
  • This training is characterized by special dimensional stability.
  • the transverse threads are designed as flat transverse threads on which Protruding longitudinal webs formed on the machine side are, the longitudinal webs in the direction of the longitudinal axis the flat transverse threads extend.
  • This measure too serves the dimensional stability of the transverse threads and ensures for the smooth paper-side surface of the flat cross threads remains as flat as possible and thus the paper web widely supported.
  • the production of such flat cross threads can by extruding the plastic material used happen.
  • the longitudinal webs can meet the respective requirements and be adapted to the manufacturing possibilities and in this Frames have any cross-section. Come into question in particular rectangular, trapezoidal and / or round Cross-sections.
  • the number of longitudinal webs is in principle not limited. Particularly favorable conditions result itself when two or three longitudinal webs are formed side by side are.
  • the flat transverse threads expediently have an extension in the longitudinal direction (running direction) of the paper machine clothing from 1 to 25 mm, preferably 10 to 15 mm, and in the thickness direction (across the plane of the paper machine clothing) from 0.2 mm to 1 mm. Fall by definition but always only under the term "flat cross threads" those where the thickness is less than the extension in the longitudinal direction of the paper machine clothing.
  • the longitudinal threads can be formed as flat threads.
  • Width from 0.5 to 5 mm and in the thickness direction go from 0.2 to 1 mm.
  • the longitudinal threads should only have one flat transverse thread each embed, like a plain weave, you can see the combination of flat and round cross threads as a unit.
  • the Dryer fabric 1 wide flat transverse threads on the paper side - designated by way of example with 2 - that of pairs of longitudinal threads - designated by way of example with 3 - involved be, each pair of longitudinal threads 3 from two longitudinal threads - exemplified with 4, 5 - exists within of a pair of longitudinal threads 3 run identically.
  • the Longitudinal thread pairs 3 tie with the flat transverse threads 2 Type of plain weave, d. H. they bind on the paper side a flat cross thread 2 and the machine side then the flat cross thread 2 and then again on the paper side the following flat cross thread 2.
  • the longitudinal threads 4, 5 of the longitudinal thread pairs 3 form in the Version below the dash-dotted line on the Front edge 8 of the dryer fabric 1 large loops - exemplary designated 9 - and small loops - exemplary designated with 10 - from.
  • the big loops 9 take turns with small loops 10.
  • the version above the dash-dotted line forms only large ones Loops 9 out. It is understood that through this representation two different types of front edges 8 are shown should be that only with a dryer a loop version is available.
  • the big loops 9 form loop eyelets 11, these loops 9 with corresponding large loops on the other front edge of the dryer fabric 1 are thus overlapped can that all loop eyelets 11 are aligned and thus form a channel through which is known per se Way a plug wire for connecting the front edges 8th pushed to form a so-called plug wire seam can be.
  • the dryer fabric 21 shown in FIG. 3 differs differs from the dryer 1 according to FIGS. 1 and 2 only through the design of the example designated 22 Cross threads.
  • These cross threads 22 are in one piece Molded strands formed.
  • Each cross thread 22 has a flat transverse thread 23 on the paper side, on the machine side thereof two longitudinal webs 24, 25 are formed side by side are.
  • the longitudinal webs 24, 25 have an essentially circular shape Cross section and increase the bending stiffness of the associated flat transverse thread 23.
  • the cross threads 22 are of longitudinal threads 26 in the same Integrated like the combination of flat cross threads 2 and machine-side round transverse threads 6, 7 at the dryer fabric 1 according to FIGS. 1 and 2.
