Definitions

  • the invention relates to a sewn felt, as it is often used in the form of press felts in paper machines to dewater a paper web.
  • the paper web is pressed between two felts or between a felt and a roll and dewatered in this way.
  • the disadvantage of this basic tissue concept lies in the poor fiber anchorage and the increased abrasion of the press felt, the tendency of the marking by the coarse background tissue in marking-sensitive papers and the low damping capacity on vibration-sensitive pressing positions.
  • the US 5 514 438 describes felts for use in a paper machine in which wraps are used in the longitudinal direction with respect to the direction of movement of the endless belts in the paper machine. These wraps are made of monofilaments surrounded by one or more layers of multifilaments. Also, this embodiment has proven to be less than optimal, since the construction of the Umwindegarne very complex and their production is so far complicated and expensive.
  • WO-A-8001086 discloses a stitched felt according to the preamble of present claim 1.
  • the invention is therefore based on the object to provide felts available, in which the fiber anchorage over the prior art is improved and the have a lower Markierne Trent and a higher damping potential over the prior art.
  • the invention includes for this purpose the essential idea to improve the seamed felts previously used in paper machines to the effect that not only extending in the direction of movement of a base fabric used as base fabric, but also the transverse thereto substantially transverse thereto wefts or a weft Structure have. It further includes the idea of providing a twisted structure, in which monofilaments, each of which is designed as a helix, enclose each other.
  • the twisted structure has a substantially circular cross-section, being formed from at least three monofilaments twisted together, since with the use of three monofilaments an approximately homogeneous and substantially circular cross-section is realized over the entire length of the twisted structure is.
  • Another significant advantage of using three monofilaments to make the pearled structure is the ease of handling of the not too thin threads that would be necessary with the use of multiple monofilaments because of the need to maintain a not too large diameter of the ply of the ply structure ,
  • three monofilaments provide sufficient strength to provide optimum strength-flexibility combination.
  • a pearled structure formed of only two monofilaments has a cross section in the form of two juxtaposed circles, while a pearled structure of four monofilaments has a substantially quadrangular shape with rounded corners.
  • the diameter of the envelope of the twisted structure increases with the inclusion of further monofilaments in the twisted structure, so that the twisted structure is inherently more rigid and thus difficult to process.
  • twisted threads of five or more single monofilaments are possible, in which case the diameter of the monofilament is chosen to be smaller.
  • At least one upper longitudinal thread layer is preferably connected to a lower layer, wherein the seam loop can be formed between upper and middle, upper and lower or middle and lower layer.
  • felts produced by means of a twisted structure in their textile ground fabric are a significantly improved fatigue strength, since here, due to the firmly twisted respectively twisted monofilaments once penetrated into the twisted structure fibers are firmly anchored in this and a wandering is hardly possible and practically does not take place.
  • the monofilaments preferably have a diameter in the range from 0.1 mm to 0.9 mm, preferably in the range from 0.1 mm to 0.5 mm and particularly preferably in the range from 0.1 mm to 0.3 mm.
  • the specific diameter here depends in particular on the number of monofilaments processed in the twisted structure, the use of three monofilaments being optimal.
  • the single monofilaments have a diameter in the range of 0.2 mm to 0.3 mm.
  • the felt according to the invention has a transverse thread density greater than 130 transverse threads per 10 cm, preferably in the range of 130 to 200 transverse threads per 10 cm, more preferably in the range of 140 to 180 transverse threads per 10 cm.
  • optimal conditions are created by the high cross-thread density of the textile base fabric that felt according to the invention has no Markierneist.
  • a particular advantage of the invention is that the felt according to the invention is optimally adjustable in terms of Elasitizi thanks and / or strength by the choice of the respective twisted structure to its respective application, for example, the paper to be dried type.
  • FIG. 2 Figure 10 shows a laminated fabric base fabric 60 in which an upper layer 70 is disposed parallel to and spaced from a lower layer 80. Between the upper layer 70 and the lower layer 80, according to this embodiment, fibers are arranged which have a felt-like structure and serve as a damping element.
  • the thickness of the above-mentioned damping element is variable according to the requirements. Also possible is a three-layered design in which fibers are arranged between an upper and a middle layer and a lower layer, respectively, for forming a felt.
  • Fig. 3 shows the schematic structure of a layer of a textile three-layered base sheet 100, shown in section along transverse threads 30, according to a further embodiment of the invention.
  • These transverse threads 30 have a twisted structure. It is also possible that this is formed from already twisted structures or a combination of monofilaments and twisted structures.
  • the longitudinal threads 40 are preferably formed from monofilaments, but like the transverse threads may be formed from twisted structures. Between the longitudinal threads 40 extending into the image plane, an additional thread layer 120 is woven in order to increase the distance between the longitudinal threads. This additional thread layer 120 can be formed both from monofilaments and from twisted thread structures. For loop formation, upper and middle, middle and lower, but preferably used upper and lower longitudinal threads.
