    [0002] REEL, TWISTING PROCESS AND TWISTING MACHINE
    [0004] OBJECT OF THE INVENTION
    [0006] The invention, as expressed in the wording of the present specification, refers to a thread spool, a thread twisting process and a thread twisting machine that provides, for the function for which it is intended, advantages and characteristics , which are described in detail later.
    [0008] The object of the present invention rests, on the one hand, on a coil of thread, specifically thread of natural, synthetic or artificial textile fibers, in which the twist of said thread wound on the coil is such that when unwinding at "from filé ”in one direction the twist of the thread is constant and is essentially zero tpm (twists per meter), while when unwinding in the opposite direction said twist is variable throughout the entire bobbin and equals 2 / (DI * n) where DI is the instantaneous winding / unwinding diameter of the coil in meters.
    [0010] Also the object of the invention, the yarn twisting process that makes it possible to generate a coil with the described characteristics.
    [0012] Lastly, yarn twisting machines that make it possible to generate a coil with the characteristics described are also the object of the invention.
    [0014] FIELD OF APPLICATION OF THE INVENTION
    [0016] The field of application of the present invention is framed in the sector from the textile industry of any type of yarn, especially delicate yarns such as fiberglass yarns.
    [0018] BACKGROUND OF THE INVENTION
    [0020] In the textile sector, twisting machines are known that on a thread or fiber bundle without twist (hereinafter thread without twist or with zero twist) apply certain turns or twists for each meter of textile thread or fiber (hereinafter thread with twist) and collect the twisted yarn into a spool.
    [0022] Said yarn collection spool can have a cylindrical, conical, double-conical or other shape on a support that can be a cardboard tube or a reel or bottle format reel container or others. In short, the format of the final coil is not limiting and depends on the subsequent process with which the coil with twisted thread will be used).
    [0024] There are different technologies of textile twisting machines that differ by having different operating principles, although the purpose of twisting and winding a thread is the same, these are generally:
    [0026] - ring twisting technology - slider (ring machines),
    [0027] - double twist twisting technology (2x1),
    [0028] - mill-type twisting technology,
    [0029] - twisting technology of the cable or cabling type ,
    [0030] - other technologies derived from these ...
    [0032] In addition to natural fibers, there are synthetic fibers and artificial fibers and new fibers or filaments are continuously being developed that improve the properties of the fiber depending on the purpose for which it is intended.
    [0033] Said diversity of new requirements for the properties of yarn fibers or fabrics also imply applying certain mechanical characteristics to the yarn, such as twisting.
    [0035] The torque applied to a yarn or fiber bundle is defined as the turns of yarn about its own axis that are applied to 1m of said yarn. The unit of torque in the metric system is turns / meter or tpm (torques per meter), although in the Anglo-Saxon system it is also used turns / inch or TPI or others.
    [0037] In a usual way in the current state of the art, the torsion value is a characteristic that adds value to the yarn by providing properties of resistance to breakage, certain elongation, S / Z torsion sense, etc., which they are generally desired to obtain a specific purpose in a later weaving, construction of a rope or others.
    [0039] In the case of ring twisting machines, it should be remembered that it is called “S” torsion when the spindle or bobbin where it is spinning or twisting rotates counterclockwise, and it is called “Z” torsion when the spindle where spinning or twisting rotates clockwise.
    [0041] In the case of machines of the double torsion type, it should be remembered that it is called “S” torsion when the rotating plate of the machine's torsion means rotates counterclockwise, and it is called “Z” torsion when the Turntable of the torsion means of the machine rotates clockwise.
    [0043] It does not go into detail about the definitions of certain parameters such as resistance to breakage, elongation, direction of torsion S / Z and many others, since they are already known in the textile sector in general.
    [0045] Even so, and as a clarification, the same thread twisted in one sense of twist or another (sense S or sense Z) can also alter the characteristics to obtain a specific purpose in a subsequent weaving, construction of a rope or others.
    [0047] For example, in terms of mechanical characteristics, a 2-strand wired wire with a structure with a first twist of 100tpm in the S direction and a second twist of 80tpm in the Z direction has nothing to do with the same wire wired to two strands with a structure with a first twist of 100tpm in the S direction and a second twist of 80 tpm also in the S direction.
    [0049] At the same time, the same yarn twisted to one degree of twist or another also changes its mechanical properties, so that, depending on the purpose for which this yarn is going to be used and the properties that are needed, it will be will apply a certain degree of twist and a direction of twist S / Z also determined.
    [0051] Regarding the structure of the twisted yarn, this can be a bundle of continuous synthetic or artificial fibers that are grouped in parallel (zero twist degree) to form an untwisted yarn and that is folded into spools on a tube support mainly of cardboard or plastic.
    [0053] Certain products, such as some textile fabrics, need to be made from yarns twisted to a certain degree of twist.
    [0055] Multiple spools of twisted yarn are generally placed in static structures, called creels, which support the spools with yarn inside the tube and facilitate / guide the unfolding of the yarns from the spools that are static in the creel towards the loom.
    [0056] This type of unfolding is done with the static coil and pulling the thread in the direction of the coil axis and is called "filé" in which it is already known that this type of unfolding varies the structure of the twisted thread, although this variation It does not imply a substantial change on the structure of the yarn with respect to when it is twisted in the coil compared to when it is unfolded and it is perfectly accepted in a large percentage of processes and textile products.
    [0058] Also, if the same type of fillet unfolding is used in bobbins that have yarn without twisting, the effect of unfolding modifies the structure of the thread in terms of twists, since in fillet unfolding certain twists are acquired in one direction. determined, the yarns being fed to the next process not under zero twist yarn conditions. The sectors of the textile that use this type of reels and unfolded generally also accept this effect without any problems.
    [0060] According to the current technique, any process in which a creel houses at least one coil with the fibers parallel (zero twist) and that guides them towards the machine or subsequent process, and, at the same time, it is also necessary that the unfolded yarn is also With zero or no torsion, the unfolding of the creel bobbins is carried out by pulling the thread from the side of the bobbin (perpendicular to the axis) and rotating the bobbin through creating a tension in the thread itself as it unfolds.
    [0062] This type of unfolding is called "roll" and the creels required for this type of unfolding are much more complicated because the bobbins must rotate and generate all the same tension and they imply that the tension of the threads generated by the rotation of the bobbins in their unfolding means that they must be compensated with additional yarn feeders between the creel and the subsequent machine such as a loom or another machine.
    [0064] At the same time the unfolding speeds are lower and limit the productivity of the process since the inertias generated by the rotational movement of the bobbins and the tensions of the yarns are very high when the spools are full of yarn.
    [0066] Due to all these problems, it would be interesting to have a coil of a thread when the thread is deployed "de filé" in a first direction, the value of the twist of the thread once deployed a de filé is constant throughout the entire coil and is essentially equal to 0 dpm.
    [0068] EXPLANATION OF THE INVENTION
    [0070] The coil of natural, synthetic or artificial textile fiber yarn, the yarn twisting process and the yarn twisting machine that the invention proposes are configured as an ideal solution to the problems described above, being the characterizing details that make it possible and that distinguish them conveniently collected in the final claims that accompany the present description.
    [0072] Specifically, what the invention proposes, as a result of the aforementioned technological need and as noted above, is, on the one hand, a coil of thread, specifically thread of natural, synthetic or artificial textile fibers, in which the twist of said yarn wound on the bobbin is such that when the yarn is unwound "flat" in a first direction, the twist of the yarn is constant and is essentially zero tpm (twists per meter), while when unwinding it "flat" in the opposite direction, said torsion is variable throughout the entire coil and is equivalent to:
    [0073] P ’(tpm) = 2 / (DI * n)
    [0075] where the ID is the instantaneous winding or unwinding diameter or in other words the diameter in meters (m) of the coil at the moment it is winding or unwinding.
    [0077] More specifically, the invention refers to a coil containing twisted yarn in which the value of the twist of the folded yarn (which we will designate as alpha) and which, as has been said, is variable and is associated with the instantaneous winding diameter / unwinding (DI) of the coil itself fulfills the following expression:
    [0079] alpha (tpm) = 1 / (DI * n)
    [0081] in such a way that, when the thread is deployed "de filé" in a first direction, the value of the twist of the thread once deployed to "de filé" (which in this case we will indicate as P) is constant throughout coil y tends to 0,
    [0083] P (tpm) = 0
    [0085] and in such a way that when the yarn is deployed "de filé" in a second direction opposite to the first direction, the value of the twist of the yarn once deployed "de filé" (P ') is variable throughout the displayed and is equivalent to:
    [0087] P ’(tpm) = 2 / (DI (m) * n)
    [0089] Also, preferably, it is emphasized that the format of the coil, which can be cylindrical, double conical conical, with plates (spool), etc., is not It is affected by the characterization of the coil as long as it meets the described torque value requirement.
    [0091] To obtain 0 tpm twist yarn, you simply have to unfold the bobbin yarn "by filé" in the correct direction so that the torsion generated by the unfolding compensates for the twist of the folded yarn. To facilitate the correct identification of the unfolding, they can be use markings on the coil.
    [0093] Another object of the invention is the yarn twisting process that makes it possible to generate a coil such as the one described above.
    [0095] The yarn twisting process essentially comprises the following stages.
    [0097] • Twisting of the wire by means of twisting means that apply a torque associated with the instantaneous winding / unwinding diameter of the bobbin itself
    [0098] • Folding the thread on a take-up spool
    [0100] such that the value of the twist of the folded yarn (a) along the entire take-up spool is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the spool itself and is equivalent to:
    [0102] a (tpm) = 1 / (DI * n)
    [0104] Also an object of the invention are twisting machines that make it possible to generate a coil such as the one described above by applying the twisting process also described.
    [0105] DESCRIPTION OF THE DRAWINGS
    [0107] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, the present specification is attached, as an integral part thereof, to a drawing in which, with an illustrative and non-limiting nature the following has been represented:
    [0109] Figures 1-A and 1-B.- They show two schematic elevational views of two examples of coil object of the invention being deployed in opposite directions. In figure 1-A a coil is observed where the unfolded thread a from filé presents a torsion (P) essentially 0, while in figure 1-B the thread unfolded a from filé of the same coil presents a torsion (P ') different from 0;

In figure 3-A it is observed that the yarn of the delivery spool (2) unwinds in a first direction causing the unfolded yarn to have a twist in the S direction while in figure 3-B the unwound yarn of the spool of delivery (2) presents a torsion in the Z direction; Y
    [0115] Figures 4-A and 4-B.- They show respective schematic representations of another example of machine of the invention, in this case a twisting machine of the 2x1 type with a yarn delivery spool (2) that is unwound at "edge". Figure 4-A shows that the yarn unwinds in a first direction causing the unfolded yarn to present a twist in the S direction while in Figure 4-B the unfolded thread presents a twist in the Z direction.
    [0117] PREFERRED EMBODIMENT OF THE INVENTION
    [0119] In view of the aforementioned figures, and in accordance with the numbering adopted, various examples of non-limiting embodiment of the invention can be seen in them, which comprises what is described in detail below.
    [0121] Thus, as seen in said figures, a primary coil or delivery coil (2), with a multifilament yarn (H), for example, made of 110 Tex polyamide and without twisting, is processed in a machine (100) twisting machine on a container that will be the support of the coil (1) of the present invention.
    [0123] The fact of using the word process implies that the twisting machine (100) feeds on the primary thread (H) that has no twist, twists the thread in a certain degree of twist and direction of rotation (S or Z) by means of torsion and the coil already twisted on the support, which, for example, is a cardboard tube with an external diameter d = 75mm, and in which the maximum diameter (D) of the coil (1) is 200mm.
    [0125] The main characteristic of the twisting machine (100) is that the value of the torque to be applied in the machine O) by the twisting means is such that the value of the twist of the folded yarn (a) is variable and is associated with the diameter instantaneous winding / unwinding (DI) of the take-up reel itself (1) and is equivalent to:
    [0126] a (tpm) = 1 / (DI (m) * n)
    [0128] For example, at the beginning of the twisting and winding cycle, it begins by winding the already twisted yarn on the 75mm cardboard tube. At this point, the twist that the folded thread must have is:
    [0130] alpha 75 = 1 / (0.075 * 3.1416) = 4.24 tpm (torques per meter)
    [0132] On the other hand, at the end of the take-up spool (1), when it reaches the maximum diameter of 200mm, the twist that the folded thread must have is:
    [0134] alpha 200 = 1 / (0.2 * 3.1416) = 1.59 tpm (torques per meter)
    [0136] As the take-up spool (1) acquires a larger diameter during the twisting and winding process, the twist that the folded thread must have will be different and will be within the values of alpha75 and alpha200.
    [0138] In the event that the format of the twisted thread spool is conical or double conical or another, proceed in the same way. That is, a torsion (Q) must be applied in the torsion means of the machine such that the value of the twist of the folded yarn (a) is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the machine itself. take-up spool (1) and is equal to:
    [0140] a (tpm) = 1 / (DI * n)
    [0142] This implies that the twisting machine (100), whatever the technology used, must know the diameter throughout the twisting process. instantaneous (DI) of the take-up spool (1) of twisted yarn since this instantaneous diameter (DI) is changing throughout the winding process.
    [0144] Taking into account figures 1-A and 1 -B, two examples of the coil (1) object of the invention can be seen with respective types of unwinding of the thread, in which it is observed how it is fulfilled that the value of the twist of the folded yarn (a) along the entire bobbin (1) is such that when the yarn is unfolded "edge-to-edge" in a first direction (S) (figure 1-A), the twist value of the yarn one Once deployed to "de filé" (P) is constant throughout the entire coil and tends to 0,
    [0146] P (tpm) = 0
    [0148] and such that, when the yarn is deployed "by filé" in a second direction (Z) (figure 1-B), contrary to the first direction (S), the value of the twist of the thread once deployed a de filé ( P ') is variable throughout the entire display and is equivalent to:
    [0150] P ’(tpm) = 2 / (DI * PI)
    [0152] Based on figure 2, a schematic representation of a first example of the machine (100) is observed, specifically a ring machine with a "roll" yarn delivery spool (2).
    [0154] In this case, the yarn (H) coming out of the delivery spool (2) of yarn that has no twist (torque value to the yarn prior to the twisting means (A) = 0), that is to say that the unfolding does not adds twist. The thread unfolded from the spool (2) passes through twisting means, in this case comprising guiding means (200), a ring-slider assembly and rotating means (300) of the take-up spool (1) , which apply a value to the machine of twist to the thread (Q) fulfilling the following formula:
    [0156] (Q) tpm = (2 / (DI1) * 3.1416),
    [0158] where: bobbin rpm (1) = (Q) tpm * linear wire speed (H).
    [0160] Taking into account figures 3-A and 3-B, another example of the machine (100) is observed, specifically a ring machine with a delivery spool (2) of thread that unfolds "from filé". The machine comprises a delivery spool (2) of yarn (H) at 0 twist, a twisting means that applies a twist to the yarn (H) to the yarn (Q), a take-up spool (1) of yarn (H) with a value of the twisting of the folded and already twisted wire (a), means to know the instantaneous diameter (DI2) of the delivery spool (2), means to know the instantaneous diameter (DI) of the take-up spool (1) and means for modifying the twist (Q) applied to the yarn in the twisting means.
    [0162] In this case the yarn that comes out of the yarn delivery spool (1) has a twist (A) as a result of unwinding, the twist value to the yarn prior to the twisting means (A) depends on the type of direction of the folded (S or Z).
    [0164] As can be seen in figure 3-A, the unfolding of the coil (2) causes the unfolded thread to have a twist in the Z direction with a torsion value prior to the twisting means (A) that is equivalent to:
    [0168] In this case, when the torsion means apply a torsion (Q) in the Z direction, the torsion (Q) must equal:
    [0169] Q (tpm) = (2 / (DI1) * 3.1416) - (1 / (DI2) * 3.1416)
    [0171] with the aim that the value of the twist of the folded thread (a) along the entire take-up spool (1) is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the take-up spool itself ( 1) and is equivalent to:
    [0172] a (tpm) = 1 / (DI (m) * n)
    [0174] On the other hand, when in this case the torsion means apply a torsion (Q) in the S direction, the torsion (Q) must equal:
    [0176] Q (tpm) = (2 / (DI1) * 3.1416) (1 / (DI2) * 3.1416) where: coil rpm (1) = Q (tpm) * linear speed (m / min).
    [0178] with the aim that the value of the twist of the folded thread (a) along the entire take-up spool (1) is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the take-up spool itself ( 1) and is equivalent to:
    [0179] a (tpm) = 1 / (DI (m) * n)
    [0181] As can be seen in figure 3-B, the unfolding causes the unfolded thread to have a torsion in the S direction with a torsion value prior to the twisting means (A) that is equivalent to:
    [0185] In this case, when the torsion means apply a torsion (Q) in the Z direction, the torsion (Q) must equal:
    [0187] Q (tpm) = (2 / (DI1) * 3.1416) (1 / (DI2) * 3.1416) where: coil rpm (1) = Q (tpm) * linear speed.
    [0188] with the aim that the value of the twist of the folded thread (a) along the entire take-up spool (1) is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the take-up spool itself ( 1) and is equivalent to:
    [0189] a (tpm) = 1 / (DI (m) * n)
    [0191] On the other hand, when in this case the torsion means apply a torsion (Q) in the S direction, the torsion (Q) must equal:
    [0193] Q (tpm) = (2 / (D11) * 3.1416) - (1 / (DI2) * 3.1416)
    [0195] Finally, taking into account figures 4-A and 4-B, another example of the machine (100) is observed, specifically a 2x1 machine with a delivery spool (2) of "filé" yarn. The machine comprises a delivery spool (2) of yarn (H) at 0 twist, a twisting means that applies a twist to the yarn (H) to the yarn (Q), a take-up spool (1) of yarn (H) with a value of the twist of the folded yarn (a), means for knowing the instantaneous diameter (DI2) of the delivery spool (2), means for knowing the instantaneous diameter (DI) of the take-up spool (1) and means to modify the twist (Q) applied to the yarn in the twisting means.
    [0197] In this case, the yarn (H) coming out of the yarn delivery spool (2) is twisted as a result of unfolding. The unfolded wire passes through twisting means, in this case comprising a rotating plate, guiding means (200), and rotating means (300) of the rotating plate of the twisting means.
    [0199] As can be seen in figure 4-A, unfolding causes the thread to unfolded delivery coil (2) has a twist in the Z direction with a torque value prior to the twisting means (A) that is equivalent to:
    [0203] In this case, when the torsion means apply a torsion (Q) in the Z direction, the torsion (Q) must equal:
    [0205] Q (tpm) = (1 / (DI1) * 3.1416) - (1 / (DI2) * 3.1416) where: rpm of the torsion means (300) / 2 = Q (tpm) * linear wire speed .
    [0207] with the aim that the value of the twist of the folded thread (a) along the entire take-up spool (1) is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the take-up spool itself ( 1) and is equivalent to:
    [0208] a (tpm) = 1 / (DI (m) * n)
    [0210] On the other hand, when in this case the torsion means apply a torsion (Q) in the S direction, the torsion (Q) must equal:
    [0212] Q (tpm) = (1 / (D11) * 3.1416) (1 / (DI2) * 3.1416) where: rpm of the torsion means (300) / 2 = Q (tpm) * linear speed of the wire .
    [0214] with the aim that the value of the twist of the folded thread (a) along the entire take-up spool (1) is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the take-up spool itself ( 1) and is equivalent to:
    [0215] a (tpm) = 1 / (DI (m) * n)
    [0216] As can be seen in figure 4-B, unfolding causes the unfolded thread to have a torsion in the S direction with a torsion value prior to the twisting means (A) that is equivalent to:
    [0220] In this case, when the torsion means apply a torsion (Q) in the Z direction, the torsion (Q) must equal:
    [0222] Q (tpm) = (1 / (D11) * 3.1416) (1 / (DI2) * 3.1416) where: rpm of the torsion means (300) / 2 = Q (tpm) * linear speed of the wire .
    [0224] with the aim that the value of the twist of the folded thread (a) along the entire take-up spool (1) is variable and is associated with the instantaneous winding / unwinding diameter (DI) of the take-up spool itself ( 1) and is equivalent to:
    [0225] a (tpm) = 1 / (DI (m) * n)
    [0227] On the other hand, when in this case the torsion means apply a torsion (Q) in the S direction, the torsion (Q) must equal:
    [0229] Q (tpm) = (1 / (DI1) * 3.1416) - (1 / (DI2) * 3.1416) where: rpm of the torsion means (300) / 2 = Q (tpm) * linear speed.
    [0231] There are various technologies to obtain the value of the instantaneous diameter of a coil throughout the entire process, such as an ultrasound sensor that is properly oriented to provide an analog signal associated with a distance to a programmable controller or PLC and that this through and programming means calculate said diameter instant. It is also possible to know the instantaneous diameter of a coil by knowing the speed of the wire, the characteristics of the wire and the geometry of the coil's folding.
    [0233] It is not considered necessary to go into detail about the way in which these textile machines twist, although preferably the present invention focuses on the fact that said machines are characterized by knowing the instantaneous diameter of the coil during the entire twisting cycle. Through programming means, they can apply a real torque to the wound wire that is variable such that the value of the twist of the folded wire (a) along the entire take-up spool (1) is variable, it is associated with the instantaneous diameter winding / unwinding (DI) of the take-up reel itself (1) and is equal to:
    [0235] a (tpm) = 1 / (DI (m) * n)
    [0237] In short, to obtain a real torsion (a) in the reception coil (1), a torsion (Q) must be programmed in the twisting machine and according to the operating principle of the machine as if it is of the type of rings or of double torsion (2x1), each machine will act on its moving parts as appropriate:
    [0239] For ring twisting machines:
    [0241] Coil RPM (1) = (Q) * line linear speed wire
    [0243] For double twist or 2x1 twisting machines:
    [0245] Average Twist RPM (300) / 2 = (Q) * Linear Speed Thread
    [0247] When we talk about the zero torsion value, it means that the objective of Torsion is zero tpm, although the tolerances of both the measurement of the diameters DI, DI2 and the precision of the movements must be such that they are always looking for said objective, therefore there must be a margin around the value 0 tpm which is preferably of 8 / -8 tpm in which it is considered protected by said present invention, even margins of 1 / -1 tpm or 2 / -2tpm, 3 / -3tpm.
    [0249] Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field understands its scope and the advantages derived from it.
