    Paper guide rope
    The present invention relates to a paper guide rope braided from several textile subunits.
    Paper guide ropes serve to guide the resulting paper web through the roller system in the various sections (eg dryer group, lcimpresses, rewinder) of the paper machine. For this purpose, usually two or three Papicrführungsseile run close together and the so-called paper tip is clamped between these ropes and so controlled guided by the sections. The Papierfuhrungsseile be guided in a circuit, i. the rope ends of a rope are spliced together to form a rope ring whose length depends on the section of the paper machine, but is usually on the order of 50 to 100 meters.
    Paper handling cables typically have a diameter of 6 to 17mm. Their essential properties result from the application: The adhesion or the clamping force between the rope and the paper must be high enough so that the paper tip can be opened up. Due to the length of the rope ring, the elongation of the rope must not be high. Breaking strength plays a minor role, but critical is the life under the adverse conditions of a paper machine.
    The life of Papierfuhrungsseilen in paper machines is limited. Depending on the section (i.e., job site) in the paper machine, the life of a rope is longer or shorter. The ropes are exposed to various influences such as heat, humidity, chemicals and especially chafing. Particularly problematic sections are the size presses, where chemicals are deposited on the pulleys and the paper guide cables come into contact with encrustations which are thus created, ie they are exposed to particularly strong abrasion.
    There have been various approaches to extend the life of the paper guide ropes by their construction.
    In EP 0 150 702 A, a so-called " reinforcement " proposed the rope with monofilaments. "Reinforcement" means a wrapping, braiding, knitting, etc. of the rope, or of the fiber material used for the production of the rope, or of subunits of the rope produced from this fiber material, wherein, however, the * «* ·· ·· ·« · · · * · «« «* *» * * I · · * ·· < * · · " · · · · · T t · t * · «· T14426
    Surface of the fiber material, the rope or the subunit is not completely covered.
    In WO 06/55995 A and ΛΤ 503 289 B further details of reinforcements for paper handling ropes are described.
    Paper guide ropes are known from US 2005/0204909, in which first a multi-filament thread is twisted with a monofilament, that is, a reinforcement is produced on the multifilament thread. The reinforced multi filament thread is then braided into small ropes, from which in turn the paper guide rope is braided. Alternatively, US 2005/0204909 describes the manufacture of a rope in which the reinforcement (monofilament wetting) is applied not to the original multifilament yarn but to the small rope braided from this yarn.
    All of these proposals have in common that a reinforcement is applied to the rope or to one of its elements (original twist, subassembly made from the twist such as small rope).
    Monofilaments used to make reinforcements have the property of breaking soon in use and rendering the rope unsightly. The rope looks obviously worn, although it would still have a long life. In the paper machines, however, the ropes are usually judged by their appearance and are decided according to their appearance on the exchange.
    Another important feature of paper guide ropes is their elongation. The ropes must be stretched during their use and stay. If a paper guide rope stretches, this change in length is compensated by means of a tensioning station so that the tension of the rope remains the same. The tensioning of the tensioning station is usually limited. Too high an elongation of the rope thus leads to the fact that it can no longer be stretched, thereby exposed to increased wear and can jump out of its orbit and therefore must be replaced. The known ropes with a reinforcement of MonofiJen have a relatively high elongation, which is constructive.
    From CZ 19446 Ul a rope is known, which is braided from a plurality of textile subunits, each consisting of only adjacent yarns. The yarns are not rotated, creating a rope with comparatively low elongation.
    The present invention has as its object to provide a paper guide rope, which exhibits a much higher abrasion resistance than conventional Papierfuhrungsseile and at the same time a sufficiently low elongation. In particular, the Papierflihrungsseil should have no reinforcement for the reasons described.
    This object is achieved with a paper-threading rope braided from a plurality of textile subunits, each subunit containing a plurality of multifilament yarn twines, and characterized in that the titer of at least a part of the twisted yarns, preferably all twisted yarns, is in each case at most 5000 dtex and that the rotation of at least a portion of the threads, preferably all threads, is at least 150 T / m in each case.
    Brief description of the figures
    Figure 1 shows a Auslührungs form of a braided Papierfuhrungsseiles Figure 2 shows another Auslass form of a braided Papierfuhrungsseiles Detailed description of the invention
    It has been found that paperboard filaments whose textile subunits are not made up of thick twines (with a thickness of, for example, 8400 dtex per twine) have a relatively low twist (typically about 80 T / m), but relatively thin twists with a very high twist Rotation, excellent properties in terms of abrasion resistance with good billing properties have.
    In particular, in the rope according to the invention, there is no need to provide additional reinforcement, so that according to a preferred embodiment of the present invention, neither the rope nor the subunits bzvv. whose threads have a reinforcement.
    The rotation of the threads in the rope according to the invention can be in each case 150 T / m to 350 T / m, preferably 150 T / m to 250 T / m, particularly preferably 200 T / m. • · · * * * * < «« «« 4 T14426
    The denier of the twines in the rope according to the invention can be in each case 400 dtex to 5000 dtex, preferably 2500 dtex to 4500 dtex, particularly preferably 4200 dtex.
    Any suitable multifilament textile yarn may be used as the fiber material for producing the threads. In particular, at least a part of the threads may consist of pile amid multifilament yarn. But it can also be provided Gaminischungen. For example, a 3-strand twisted yarn may be made of a yarn of polyamide and two yarns of another material, e.g. Polyester, consist.
    The multifilament yarns or the threads made therefrom may optionally be impregnated in known manner and / or heat-set. Also, the entire rope can be impregnated in a conventional manner and / or heat-set.
    The number of threads per subunit is preferably at least 7, more preferably 9 to 16.
    By the term " subunit " For the purposes of the present invention, those accumulations of fibrous material which are parallel and adjacent to each other in the rope, e.g. a multitude of threads lying side by side, plaited twines or twisted threads.
    To demonstrate the term " subunit " 1 and 2 show two different embodiments of a Papierfuhrungsseiles. 1
    In the embodiment according to FIG. 1, the cable 1 is made up of subunits 2 (here: braided braids) which each contain more than seven threads 3. These subunits 2 can each be produced by means of two bobbins running one behind the other, from which the shape of a braided diamond results (framed in FIG. 1). In the subunits, the threads lie essentially parallel next to one another.
    In the embodiment according to FIG. 2, the cable 1 is likewise constructed from sub-units 2, which are each manufactured by means of two bobbins. This results in two at least partially adjacent elements 2 ', 2 " (which are framed in Figure 2). The from the adjacent sections of the two elements 2 ', 2 " existing subunit 2 again has at least seven threads. Also in this 5 T 14426
    Auslass form are the threads in the subunits 2 and their elements 2 2 " essentially next to each other.
    Analogously, this definition of the subunit is also applicable to embodiments that result from the succession of more than two bobbins in the two directions of travel S and Z. However, such a rope construction is not provided on the current braiding today.
    The paper guide rope according to the invention may be in the form of a floats rope or a rope with a core.
    Examples:
    The following four ropes were produced: 1) Rope according to the invention:
    Twisted thread of PA6 multifilament: 1400 dtex x3 200T / m (in S- resp. Z-direction)
    This thread is impregnated.
    Construction of the rope: Braided on a 16-bobbin weaving machine with the following cast: S-direction: 8 bobbins with 5 S-twists Z-direction: 4 bobbins with 5 Z-twines and 4 bobbins with 4 Z-twines The subunit in S-direction it consists of 10 Zw'imen.
    The subunit in the Z direction thus consists of 9 warning signs. 2) Paper guide rope in usual construction with reduced twists:
    Twisted thread of PA6 multifilament: 1400 dtex x6 20T / m (in S or Z direction)
    This thread is impregnated.
    Structure of the rope: Braided on a 16-bobbin weaving machine with the following cast: S-direction: 8 bobbins with 2 S-twists Z-direction: 6 bobbins with 3 Z-twines and 2 bobbins with 2 Z-twines each 3 ) Paper guide rope of usual construction (with usual twists): Μ Φ ·················································································································. · · * · 6 Γ 14426
    Twisted thread of ΡΑ6 multifilament: 1400 dtex x6 80T / m (in S or Z direction)
    This thread is impregnated.
    Structure of the rope: Braided on a 16-bobbin weaving machine with the following cast: S-direction: 8 bobbins with 2 S-twist Z-direction: 4 bobbins with 3 Z-twist and 4 bobbins with 2 Z-twist each 4) Rope with monofilament reinforcement
    Structure of the rope: Braided on a 16-bobbin weaving machine with the following cast: S-direction: 8 bobbins with 1 S-element Z-direction: 8 bobbins with 1 Z-element each S-element: 2 S-twists (PA6 multifilament 1400 dtex x6 80T / m) braided with 16 PA
    Monofils (Diameter 0.2mm) Z-Klement: 2 Z-Zwime (PA6 Multifilamenl 1400 dtex x6 80T / m) braided with 16 PA
    Monofilaments (diameter 0,2mm)
    Measuring method of dry expansion:
    At 1kg load is marked in the rope. Then a load of 80 kg is applied. 5 minutes loaded and then read the elongation. Elongation in cm = elongation in%
    Measuring method of wet stretch:
    Like dry stretch, but after marking the rope, the rope is placed in 25 ° C cold water for 5 minutes.
    The elongation values measured on the above ropes 1) to 4) are shown in the following table:
    Dry elongation Wet elongation%% Rope 1) (according to the invention) 2.4 4.4 Rope 2) 1.8 3.5 From 3) 1.9 3.5 7 T14426
    Dry elongation Wet elongation%% Rope 4) 2.8 4.5
    Durability and abrasion resistance data:
    The measure of the service life is the residual breaking load in [% | after a simulated run in a wet section of a paper machine. For this purpose, a test unit has been developed that consists of 10 rollers. The rope runs at 800m / min and is sprayed with water (consumption: 1.6 1 / h). The rope is operated under 30kg tension, and to achieve an additional abrasion effect some pulleys are not aligned - i.e. the rope runs slightly over the pulley flank.
    The residual strength of the ropes 1) to 4) after 24h of this experiment is given in the following table: 24h residual strength% rope 1) (according to the invention) 56.7 rope 2) 24.3 rope 3) 49.2 rope 4) 39.5
    It can clearly be seen that the cable according to the invention has an improved residual strength with at the same time satisfactory elongation properties. An optical assessment of the rope gives a satisfactory appearance, while, for example, the rope 3 has significant signs of wear.
