Definitions

  • the invention relates to a rope for the entrainment and transfer of paper webs in the manufacture of paper and cardboard on paper machines from round braided textile fiber material.
  • Ropes made of braided textile fiber material are known in a wide variety of configurations. From DE 40 35 814 A1, for example, a rope is known which consists of a core and a braided sheath in particular, the core being designed with low stretch, ie having a low elongation behavior and a high modulus of elasticity.
  • the aim of this prior art is to reduce the relative movement between a core and a sheath surrounding it, in particular when the rope is clamped to the sheath.
  • the core and the sheath are formed from a large number of thin polyamide fibers, which are combined to form different assemblies of the fiber rope.
  • the jacket is made from a mixture of low-stretch and normal-stretch fibers.
  • the number of low-stretch fibers is in particular 17% to 25%. This reduces the stretching behavior of the jacket to such an extent that it corresponds to that of the core, which results in a relative movement due to different stretching is prevented. At the same time, however, the friction coefficients of the core and the jacket are brought closer to one another.
  • the fibers can also consist of polyethylene or polypropylene.
  • DE 25 05 568 A1 discloses the creation of cable structures which serve as reinforcement for solid, elastic or easily deformable materials (e.g. cord for car tires) and which have an increased resistance to fatigue and / or wear.
  • the basic idea here is to reduce the radial pressures or pressures which prevail between the installation positions of a cable and between these and the soul.
  • the components of the cable i.e. the core and at least one outer layer are designed in such a way that at least two successive constituents, which touch one another radially, are formed from materials with different moduli of elasticity. As a component is "softer", contact areas between two components are enlarged and the surface pressure is reduced.
  • AT 367 112 B relates to increasing the lifespan of a rope made of aromatic polyamide with several layers of rope elements that are laid over a core to the rope.
  • the rope consists of a cardiac cord, of an inner strand layer, which is twisted around the cardiac strand and made up of strands, an outer strand layer bordering the inner strand layer, which also consists of strands that run parallel to the twist of the strands of the inner strand layer Have twist, and arranged between the inner and outer strand layer monofilament bundles.
  • the cardiac strand and the strands of the inner and outer strand layer are composed of monofilament bundles. This reduces the surface pressure on the guide lines, which increases the service life.
  • US 4,563,869 relates to a line plant, in particular a heavy-duty marine rope, with safety features in order to protect people from damage caused by a rope break. If all components of a rope break at the same time, the two separate pieces of rope fly away from the break point at enormous speed, which puts the people in this area at great risk. It is proposed here to produce a multi-component rope, preferably made of synthetic material, which consists of a certain number of components with a large elongation behavior and a certain number of components with a relatively low elongation behavior, the quantity of the latter components predominating. According to a development of this idea, the outer strands of the rope have a plurality of cover threads, which are formed from a material with higher abrasion resistance.
  • DE 35 13 093 A1 discloses a method for producing a riser cable as a drive element for motor vehicle sunroofs, which is intended to be sound-absorbing and wear-resistant.
  • a rising cable which is moved in the longitudinal direction is covered with a flocked thread.
  • a plate which takes up a bobbin with the thread, rotates around the central axis of the rising cable.
  • the so-called paper guide ropes are made of textile fiber material, both cellulose-based fibers and fibers from organic chain polymers such as polyacrylic, polyamide, polyester, polypropylene, polyethylene, polyvinyl alcohol and the like being used.
  • the ropes used as paper guide ropes consist on the one hand of ropes made of twisted or laid strands and on the other hand of braided ropes.
  • the braided ropes can be used as braided hollow ropes or in the form of ropes in a core / sheath construction.
  • the braided paper guide ropes have established themselves worldwide over their twisted ropes due to their long service life, low operational stretch, excellent abrasion and abrasion resistance and easy splicability. In some cases, however, there are also design-related conditions on paper machines in which twisted ropes are preferred, since the coarsely structured surface of the twisted ropes gives advantages in paper web clamping compared to the comparatively smoother structure of braided ropes.
  • the object of the invention is to combine the aforementioned advantages of braided ropes, such as long service life, low operational expansion, good spliceability and high abrasion protection, with the advantage of the roughly structured surface in the case of twisted ropes, in order to achieve an even better paper web clamping.
  • this task is based on a generic rope according to the preamble of claim 1 characterizing features of claim 1 solved.
  • raised areas on the rope surface are created in the course of the braiding process or two types of fibers with different properties are used in a targeted manner. The two measures that solve the task are combined particularly advantageously.
  • the present invention provides a rope that combines low rope elongation by maintaining the round braiding technology on the one hand and a significantly improved grip on the other hand.
  • the creation of the raised areas in the rope braiding of round braided ropes advantageously takes place over the entire rope circumference at regular or irregular intervals of 0.1 to 10 cm, preferably 1 to 5 cm.
  • the raised areas are generated, for example, by appropriate setting of the braiding machine parameters, such as filling the braiding machine, choosing the lay length, etc.
  • Multifilament yarns or staple fiber yarns are preferably used for the braiding process, single fiber titer from 1.6 to 30 dtex, preferably 6 to 25 dtex, and yarn titer from 200 to 17,000 dtex, preferably 700 to 10,000 dtex, being used. These yarns are advantageously used either individually or folded or twisted or in combinations thereof.
  • the yarns mentioned can be provided with a protective twist or twisted and can be equipped with various impregnations, for example hydrophobic finishes, anti-abrasion agents, color pigment finishes, etc.
  • Fibers based on cellulose such as cotton, hemp, regenerated cellulose fiber and similar usable.
  • fibers based on synthetic, thread-forming chain molecules can also be used, such as, for example, polyacrylnytril, polyamide, polyester, polyvinyl alcohol, polypropylene, polyethylene and the like. Due to the good textile mechanical data, as well as sufficient chemical and temperature resistance in the paper machine environment, fibers based on polyamide, polyacrylic, polyester or cellulose are preferably used.
  • the aforementioned object is also achieved by using two types of fibers or fiber yarns in the rope, this solution being used either alone or in combination with the features of the braided rope with raised areas described above.
  • the creation of the aforementioned, design-related, raised areas can additionally be achieved by the targeted use of fibers with a profiled fiber cross-section and / or the use of textured or crimped multifilament yarns and / or staple fiber yarns in addition to the smooth multifilament yarns commonly used. Both the use of profiled fibers and yarns with crimp or texturing leads to increased bulk volume with the same fiber titer as with smooth yarns and thus to the formation of the desired raised areas.
  • the fibers or yarns must be used in such a way that the profiled fibers or crimped multifilament yarns predominantly come to rest at the raised areas. Otherwise, the previous statements apply with regard to the other properties such as fiber and yarn titer, shedding, rotation, impregnation and selection of the chain polymers.
  • FIG. 1 shows a paper machine in which drying cylinders are shown at 14 in the embodiment shown here over which the paper webs are guided.
  • a felt running over the drying cylinders is designated by 12 (dashed line).
  • the rope 10 for paper guidance is shown in a solid line. This is clamped to the desired extent via clamping devices 16.
  • a first embodiment of the present invention is shown in FIG.
  • the threading in the running direction 18 is chosen to be higher (16 threads) than in the opposite direction 20 (8 threads).
  • multifilament yarns made of polyamide (PA 6) are used, the base yarns used having the same titer. They are hydrophobically finished and have a rotation of 140 T / m. Due to the different threading, raised areas are formed at a distance of 1.8 cm, with measurements being taken from the center of the raised area to the center of the next raised area.
  • a hollow braid is realized (example 1).
  • FIG. 3 shows a further exemplary embodiment of the invention in the form of a round braided rope 10, the threading in the running direction 18 being higher (14 threads) than in the opposite direction 20 (8 threads).
  • 20 multifilament yarns made of polyamide (PA 66) are used for the running directions and 18 staple fiber yarns made of polyacrylonitrile of the same yarn titer are used for the opposite running direction.
  • the polyamide multifilament yarns are hydrophobically finished and the polyacrylonitrile staple fiber yarns are not used.
  • a core-sheath construction of the rope 10 is selected here, a core 22 consisting of knotted polyamide yarns (PA 66). Due to the different threading, raised areas are formed at a distance of 1.8 cm (measured from the center of one elevation to the center of the next elevation) (Example 2).
  • FIG. 4 shows a third embodiment of the invention in the form of a round braided rope 10, the raised areas 24 consisting of cotton yarns with a basic titer of 9,000 dtex, which are knitted into strands of 13,500 tex.
  • the other parts 26 are formed from smooth multifilament yarns with a basic titer of 9,000 dtex with 8 threads. Both types of yarn are equipped with abrasion protection including a color pigment component.
  • the round braid is designed as a hollow rope construction.
  • the raised areas are at a distance of 1.8 cm from each other (measured from the center of one survey to the center of the following survey) (Example 3).
  • a further embodiment of the invention can be explained by referring again to FIG. 3, with the raised points in the running direction 18 being formed by crimped multifilament yarns in which the individual fibers are profiled in a Y-shape.
  • the yarn titer is 4,500 dtex / 16 threads.
  • smooth multifilament yarns with the same yarn titer and the same thread are used.
  • the braid is a core-sheath construction, the sheath made of polyamide 6 and the knocked core 22 made of polyester fibers.
  • the raised areas are at a distance of 1.8 cm (measured from the center of one elevation to the center of the next elevation) (Example 4).
  • FIG. 5 shows as a further exemplary embodiment of the invention a round braided rope with raised areas, these raised areas being formed from textured multifilament yarns with a basic titer of 4,500 dtex, which were knitted into strands of 6,750 tex.
  • Parts 30 and 32 consist of multifilament yarns with a basic titer of 4,500 dtex and are 16-ply.
  • the sublime Locations are 3.5 cm apart (measured from the center of one survey to the center of the next survey).
  • the round braid is designed here as a hollow rope (example 5).
  • the diameters of the aforementioned ropes are usually 5 to 20 mm, preferably between 8 and 15 mm.
  • FIGS. 6 and 7 show paper guide ropes according to the prior art, in FIG. 6 a round braided rope made of polyamide (example 6) and in FIG. 7 a knotted rope made of polyamide (example 7) are shown.
  • the rope was attached at one point and two marking points were attached to the rope at a distance of one meter.
  • the rope is loaded with a specified weight of 80 kg and after one minute the distance between the markings is measured and the change in length that occurs is determined and calculated as a percentage of the unloaded initial length.
  • Examples 1-5 show that due to the measures according to the invention, the grip is significantly improved compared to conventional round braided ropes (cf. Example 6). The grip is even significantly improved compared to the rotated reference rope (example 7). Despite this improvement in grip, the rope elongation is not essential in all examples 1-5 according to the invention that of the round braided reference rope deteriorated. In any case, it is much better than the elongation of the twisted reference rope.
