Description

The present invention relates to a yarn manufacturing method and a yarn manufacturing apparatus.

Yarn manufacturing methods and yarn manufacturing equipment are, in principle, well known from a wide variety of different embodiments of the prior art.

A well-known method for producing yarns formed by spinning at least two individual fibers, for example as a ring spinning method, comprises the following steps: spinning to form the yarns to be produced. At least one spindle element using a step of providing at least two individual fibers and a guide device provided with the at least two fibers, particularly with a cylindrical or columnar guide element. A step of supplying the supplied spinning device to the spinning device and a step of spinning the supplied fiber in the spinning device to form a yarn to be manufactured.

While the corresponding yarn manufacturing methods are well understood about the effects of the properties of the yarns they can produce, they are nevertheless constantly developing methods that enable the production of yarns with improved properties. There is a need to. In particular, a means capable of producing a yarn having improved properties with respect to the formation of so-called neps (knops, burls), i.e. a yarn having a low tendency to form a nep, or a yarn having a low fluff. Need to develop.

The present invention is based on an object of providing an improved method for producing a yarn, particularly with respect to the production of the yarn with improved properties.

This object is achieved by the method of claim 1. A claim subordinate to claim 1 relates to a possible embodiment of the method.

In general, the methods described herein are useful for producing at least one yarn. As a matter of course, a plurality of yarns can also be produced by the method according to the corresponding method.

The method comprises three essential steps, which are described in detail below. In the first step of this method, at least two individual fibers are provided and the fibers are spun together to form a yarn to be produced. These fibers may be, for example, staple fibers. These fibers may be referred to as slabs or pre-yarns, or may be considered. Therefore, when "fiber" is referred to herein, it may be understood that this "fiber" means blister or playan. In either case, these fibers may be supplied using a fiber supply unit, for example a fiber bobbin, from which the fiber supply unit is spun into yarn within the framework of the method. The fibers are unraveled. The number of these fiber supply units is usually determined according to the number of fibers spun into yarn by the method.

In the second step of the method, the provided at least two fibers are fed to a spinning device with at least one spindle element or bobbin element using a guide device with a plurality of guide elements. To. Therefore, in the second step of the method, these fibers spun into the yarn are supplied to the spinning device using a guide device. This guide device usually includes a plurality of guide elements. These guide elements are usually arranged continuously in the guide direction of the fiber, and guide from the first guide element to another guide element arranged downstream of the first guide element in the guide direction of the fiber. It is possible to guide the fibers to be produced. The first guide element of the guide device in the fiber guide direction is arranged immediately downstream of each fiber supply unit in the fiber guide direction. The final guide element in the fiber guide direction is located just upstream of the spinning machine in the fiber guide direction. Appropriate support elements, for example plate-shaped or disk-shaped, may be provided between the guide elements that are separated in the guide direction of the fiber and arranged one after another (immediately) in the guide direction of the fiber. The support element provides the desired support for the guided fibers. Further, for example, an appropriate support element may be arranged between the first guide element and the fiber supply unit.

Usually, each guide element has a cylindrical or cylindrical geometric shape or basic shape. Thus, these guide elements may be referred to or considered as guide rollers or guide rolls, or cylinders. Typically, each cylindrical or columnar guide element is rotatably attached around the axis of symmetry or central axis of these guide elements, and the guide element rotates around each of these axes of symmetry or central axis. The motion allows the fiber to be guided in the direction of the spinning device.

The individual, multiple, or all guide elements may be provided with a specific adhesive region or specific adhesive surface, for example realized by a rubber coating, due to the adhesive effect exerted on the fibers. The adhesive surface allows for the desired guidance of the fiber, i.e., preventing or preventing unwanted sliding of the fiber in the lateral direction, particularly with respect to the guiding direction of the fiber.

In the third step of the method, the fibers supplied to the spinning device are spun in the spinning device to form the yarn to be produced. Usually, the spinning of the fibers to form the yarn to be produced is done in the spinning region next to the last guide element. The spinning apparatus includes at least one spindle element or bobbin element, and fibers spun together or a yarn formed by spinning these fibers are wound around the spindle element or bobbin element. .. The spindle element or bobbin element may be a bobbin or bobbin (cop). The number of spindle or bobbin elements, or the number of spinning regions resulting from them, is determined according to the number of yarns produced.

According to this method, in contrast to the conventional method, one (common) guide element is not used, and at least two individual, particularly cylindrical or columnar guide elements are used for spinning. At least two fibers to be threaded are supplied to the spinning apparatus, and the at least two guide elements are arranged so as to be spatially separated from each other in at least one spatial direction. In other words, the first fiber spun to form the produced yarn is fed to the spinning apparatus using the first guide element and spun together with the first fiber to form the produced yarn. A second fiber is supplied to the spinning device using a second guide element, which is arranged such that the second guide element is separated from the first guide element in at least one spatial direction.

Thus, within the framework of the method, guide devices with at least two separate, particularly cylindrical or columnar guide elements are used, the guide elements each other in at least one spatial direction, just upstream of the spinning device. Arranged so as to be spatially separated from each other. Thus, the guidance device used within the framework of the method comprises at least two final guidance elements. As shown below, these guide elements are typically placed at the same level with respect to the spinning machine, i.e., at the same distance from the spinning machine, but laterally offset from each other. Be placed. At least two fibers are fed to the spinning machine using at least two separate guide elements, and these at least two fibers are separated from each other in at least one spatial direction just before they are put together at the confluence of the fibers. It can be understood from the above explanation that the fibers are arranged so as to be arranged. Departing the guide device by supplying the fibers to be spun into yarn using at least two separate guide elements arranged spatially separated from each other in at least one spatial direction. From to the confluence of the fibers in which the fibers are bundled, the free length of the fibers that are spun into yarn can be affected, i.e., in particular the free length of the fibers can be increased. This has a positive effect on the characteristics of the produced yarn or the characteristics of the produced yarn. The increased free length of these fibers means that when the fibers are fed using separate guide elements, the confluence of the fibers from which these fibers are bundled is relatively far from the final guide element. This is due to the fact that, as a result, the confluence is significantly closer to the spinning equipment.

Usually, the confluence of the corresponding fibers represents part of the so-called spinning triangle. The confluence of the fibers in this case usually forms the apex of the spinning triangle facing the spinning device. Therefore, in the free length of the fibers forming the sides of the spun triangle, the shape of the spun triangle is the conventional method because the spun triangle is "stretched" in the guiding direction of the fibers due to the aforementioned increase. It may be modified according to the method compared with.

The method departs from the guide device, i.e., from each final guide element (from a fiber point of view) to the confluence of the fibers where these fibers are bundled, spun into yarn. By influencing the free length of the fibers, in particular by increasing the free length of the fibers, it is possible to obtain certain properties of the produced yarn or of the produced yarn, especially mechanical properties. Based on the discovery. This is especially due to the fact that the free length of the fibers that are spun into yarn increases (significantly) before the confluence of the fibers when compared to conventional methods. The (individual) fibers may already be (significantly) twisted before the fiber confluence, which has a positive effect on the properties of the yarn produced or the properties of the yarn produced. There is. Studies have shown that such methods can reduce the formation of so-called neps (nops, crowbars) in particular. Therefore, yarns produced according to this method are (significantly) less prone to forming neps and (significantly) less fluffy. Therefore, a yarn having improved properties can be produced by this method.

The free length of each fiber between the guide device and the confluence may be, for example, in the range of approximately 4 to 20 cm, particularly in the range of 7.5 to 15 cm, preferably 10 cm. .. In particular, particularly advantageous fiber properties can be obtained from a fiber length of at least 4 cm, especially from a fiber length of at least 6 cm. However, in principle, exceptions above and below these numbers are possible.

According to this method, in particular, a spinning device is used, in which the spindle element or bobbin element of the spinning device is placed between these guide elements due to the spatially spaced arrangement of the guided elements assigned in the guiding direction of the fiber. It is arranged in line with the space formed in. Therefore, the spindle element or bobbin element is arranged laterally offset with respect to the guide direction of the fiber in relation to the assigned guide element. In particular, the spindle element or bobbin element is separated from the guide element in the fiber guide direction, while being centrally located between the guide elements assigned to it. The same applies to spinning multiple yarns, each consisting of at least two fibers. In this case, in the guide direction of the fiber, the spatially separated arrangement of the respective guide elements creates a space in which each spindle element or bobbin element is formed between the guide elements assigned to them. They are arranged side by side.

As mentioned above, the guide elements are usually placed at the same level with respect to the spinning machine, but are laterally offset from each other. Therefore, within the framework of this method, they are arranged so as to be spatially separated from each other in the spatial direction, or are arbitrarily inclined in the lateral direction with respect to the guiding direction of the fibers, and are spatially separated from each other in an extending plane. At least two guide elements arranged so as to be separated from each other are particularly used. When guide elements, each having a cylindrical or cylindrical basic shape, are used, these guide elements are typically arranged coaxially and spatially with respect to each other in the direction of the central axis of each guide element. Arranged so that they are separated. They are arranged so as to be spatially separated from each other in the spatial direction, or laterally or inclined with respect to the guiding direction of the fibers so as to be spatially separated from each other in the extending plane. The two guide elements may be referred to as a pair of guide elements assigned to a particular spindle element or bobbin element, or may be considered. The pair of guide elements are used to supply the fibers forming the yarn that is wound around each spindle element or bobbin element.

The free length between each point where each fiber departs from each guide element in the direction of the confluence may be, for example, in the range of 4-10 cm, especially in the range of 5-9 cm. It may be, preferably 6 cm. However, in principle, exceptions above and below these numbers are possible.

They are arranged so as to be spatially separated from each other in the spatial direction, or laterally or inclined with respect to the guiding direction of the fibers so as to be spatially separated from each other in the extending plane. In addition to the described uses of the placement of the guide elements, as an alternative or in addition, at least in principle, to each other in the direction of the fibers or in the spatial direction extending parallel to the guided plane of the fibers. It is also possible to use at least two guide elements that are spatially spaced apart from each other. Therefore, at least in principle, guide elements arranged so as to be offset in the guide direction of the fiber may also be used.

As mentioned above, these fibers are grouped together at the confluence of the fibers. As also mentioned above, the confluence of the fibers usually forms the apex of the spinning triangle facing the spinning device. The angle of the spinning triangle in the region of the apex facing the spinning device is usually in the range 0-90 ° or 1-90 °. In particular, the angle is less than 90 °, especially less than 45 °, especially less than 30 °. Therefore, the angle between at least two fibers after each guide element departs is typically in the range 0-90 ° or 1-90 °. In particular, the angle is less than 90 °, especially less than 45 °, especially less than 30 °. Therefore, the angle is usually an acute angle.

Within the framework of this method, it is also possible that at least three fibers are spun together to form a yarn. These at least three fibers are usually grouped together at the confluence of the fibers. Therefore, the yarn may be made from more than two fibers (multi-fiber yarns).

By spinning at least three fibers to form the yarn according to the method, at least two fibers are fed together to the spinning device using the first guide element and at least one spatial or planar. With additional guide elements arranged spatially separated from the first guide element, at least one additional fiber can be supplied. Therefore, the first guide element can be used to supply at least two fibers, and the additional guide element can be used to supply at least one additional fiber. In this connection, it is possible to divide the fibers evenly or unevenly into a predetermined number of guide elements, in the case of the supply of four fibers as an example and the number of two guide elements as an example. Two fibers are supplied from the first guide element and two fibers are supplied from the second guide element, or three fibers are supplied from the first guide element and One fiber is supplied from the second guide element.

Alternatively, according to the method, spinning at least three fibers to form a yarn is achieved by allowing the at least three fibers to be fed to the spinning apparatus using three separate guide elements. The three individual guide elements are arranged so as to be separated from each other in at least one spatial direction or plane, and at least one first fiber is supplied using the first guide element. , At least one second fiber is supplied using a second guide element disposed spatially separated from the first guide element in at least one spatial direction or plane. The third fiber is supplied using a third guide element arranged so as to be spatially separated from the second guide element in at least one spatial direction or plane. As a result, each fiber may also be supplied with a separate guide element.

Within the framework of the method, at least two fibers and at least one filament-which may be a single filament or a multifilament-can be spun together to form a yarn. Usually, at least two of these fibers and the at least one filament are grouped together at the confluence of the fibers. Therefore, the yarn may be made from at least two fibers and at least one filament. A suitable filament may be a continuous filament. Suitable filaments may be made of elastic filament material or may include elastic filament material. The filament may be, for example, elastane (sometimes referred to as Lycra®), polyamide, polyester or polypropylene filament.

Spinning at least two fibers and at least one filament according to the method is performed by allowing the at least two fibers to be fed to the spinning apparatus using two separate guide elements. The two separate guide elements are arranged such that they are separated from each other in at least one spatial direction or plane, and the at least one filament is particularly spooled, eg, for example, a filament bobbin. It is fed from a (individual) filament storage unit in the shape or spool shape, or the at least one filament is fed using a third guide element that is separate from the two separate guide elements described above. I am trying to do it.

As a matter of course, at least two fibers can be supplied to the spinning apparatus with pretension generated by drafting the fibers, especially by pulling the fibers in the longitudinal direction. The same applies to the supplied filaments. Especially in this case, it is possible to incorporate different traction regions or different traction sections, eg, pre-draft and main draft sections, in which the fibers and / or filaments provide different degrees of traction. is recieving.

Within the framework of the method, fibers with identical and non-identical chemical and / or geometric and / or physical properties, especially mechanical properties, may be spun together to form a yarn. .. Thus, if the fibers are not identical, the fibers spun according to the method have at least one point of chemical property, i.e., at least one that is particularly relevant to the chemical properties of the fibers, eg, chemical components, for example. It may differ in one property and / or at least one property point, i.e., for example, at least one property particularly related to the geometry of the fiber, such as the diameter of the fiber. And / or at least one physical property, particularly a mechanical property, ie, for example, the strength of the fiber, especially the physical property of the fiber, especially the mechanical property. It may differ in at least one property.

Currently, as a general rule, within the framework of this method, all natural fibers, such as alpaca fibers, cotton fibers, cashmere fibers, mohair fibers, silk fibers, hemp fibers, wool fibers, especially new wool fibers, etc. And / or all chemical fibers (synthetic fibers), such as plastic fibers, in particular polyamide fibers, polyester fibers, polypropylene fibers, biscous fibers, etc., may be spun together to form the produced yarn. , Should be discussed in general. In particular, it is also possible to combine natural fibers and chemical fibers. These fibers may be continuous fibers or staple fibers, depending on availability.

The (individual) fibers may be made of at least two fibrous materials that are chemically and / or geometrically and / or physically different, or may include such fibrous materials. Thus, even if suitable fibers, also referred to as blended fibers (blended roving), are made of, for example, a first fiber material (crude material) and at least one additional fiber material (crude material). Good. The first fiber material may be, for example, a natural fiber material such as wool, and this further fiber material is, for example, a chemical fiber (synthetic fiber) such as polyamide, polyester or polypropylene. May be good. As mentioned above, these fibers may be continuous fibers or staple fibers, depending on availability.

In addition to the method, the present invention relates to or is made of yarn produced by the described method and is formed using the described yarn produced by the method. Or with respect to a textile product comprising at least one thread thus produced. The textile product may be a semi-finished product (precursor) or a finished product (final product).

Furthermore, the present invention relates to a yarn manufacturing apparatus formed by spinning at least two individual fibers by a method specifically described. Therefore, all statements made in connection with this method apply mutatis mutandis to this device.

The manufacturing apparatus is an indispensable component, particularly a guide device having a plurality of cylindrical or columnar guide elements, and at least one spindle element or a guide device arranged downstream of the guide device in the guide direction of the fiber. With a spinning device comprising a bobbin element, the guiding device is configured to guide a large number of fibers to a spinning device located downstream of the guiding device in the guiding direction of the fiber, the spindle element or The bobbin element is rotatably attached around the spindle shaft or bobbin shaft so that the spinning device spins at least two of these fibers supplied using the guide device together to form a thread. It is composed of.

The manufacturing apparatus comprises a guide device comprising at least two separate, particularly cylindrical or columnar guide elements such that the guide elements are spatially separated from each other in at least one spatial direction or plane. It is identified by the fact that it is arranged and the guide element can be used to feed at least two fibers to or to the spinning machine. Thus, the guide device comprises at least two distinct, particularly cylindrical or columnar guide elements arranged spatially separated from each other in at least one spatial direction or plane. As a result, the guide device comprises at least two last guide elements, which are usually arranged at the same level with respect to the spinning device, but laterally offset from each other.

The manufacturing apparatus may be formed as, for example, a ring spinning machine or a ring spinning device, or may be provided with a ring spinning machine or a ring spinning device.

The spindle element or bobbin element of the spinning device is particularly arranged in alignment with the space formed between the guide elements by the spatially separated arrangement of the guide elements assigned in the guide direction of the fiber. Therefore, each spindle element or bobbin element of this spinning device is arranged laterally offset with respect to the assigned guide element with respect to the fiber guide direction. In particular, the spindle element or bobbin element is separated from the guide element in the fiber guide direction, while being placed in the center between the guide elements assigned to them. The same applies to spinning multiple yarns from at least two fibers each. In this case, each spindle element or bobbin element is placed in a space formed between the guide elements assigned to each of the guide elements, respectively, due to the spatially separated arrangement of the guide elements assigned in the guide direction of the fiber. Arranged in line.

Thus, as already described above in connection with this method, the free length of the fibers spun into yarn is increased from the departure of the guide device to the confluence of the fibers in which the fibers are bundled. This can have a positive effect on the properties of the yarn produced or the properties of the yarn produced. Therefore, the production apparatus can be used to produce yarns with improved properties.

As mentioned above, these guide elements are arranged at the same level, especially with respect to the spinning machine, but are laterally offset from each other. As a result, the manufacturing apparatus is provided with at least two guide elements in particular, and the guide elements are arranged so as to be spatially separated from each other in the spatial direction, or laterally to the guide direction of the fiber. , Arbitrarily tilted and arranged so as to be spatially separated from each other in an extending plane. In either case, when the manufacturing apparatus includes guide elements having a cylindrical or columnar basic shape, these guide elements are usually arranged coaxially and in the direction of the central axis of each guide element. , Arranged so as to be spatially separated from each other. They are arranged so as to be spatially separated from each other in the spatial direction, or laterally or inclined with respect to the guiding direction of the fibers so as to be spatially separated from each other in an extending plane. The two guide elements may be referred to as a pair of guide elements assigned to a particular spindle element or bobbin element, or may be considered. The pair of guide elements may be used to supply fibers forming threads that are wound around each spindle element or bobbin element.

Alternatively or additionally, at least in principle, at least two arranged spatially separated from each other in the direction of fiber guidance or in the direction of space extending parallel to the fiber's guided plane. It is also possible for the manufacturing apparatus to include two guide elements. Therefore, at least in principle, the manufacturing apparatus can also include guide elements arranged so as to be offset in the guide direction of the fibers.

The manufacturing apparatus may include a traction device, which is configured for traction of fibers supplied to the spinning apparatus, and is particularly configured for longitudinal traction of the fibers. This traction device may be functionally and / or structurally incorporated into the guidance device. The traction device allows different traction regions or different traction sections, such as pre-draft and main draft sections, to be incorporated, in which the fibers are subjected to different degrees of traction. ..

The present invention will be described in more detail with reference to exemplary embodiments in the drawings. The drawing shows:
It is the schematic of the yarn manufacturing apparatus by an exemplary embodiment. It is the schematic of the yarn manufacturing apparatus by an exemplary embodiment. It is an enlarged view of detail III shown in FIG. It is an enlarged view of the detailed IV shown in FIG.

A guide device 5 arranged downstream of the fiber guide direction and a spinning device 6 arranged downstream of the guide device 5 in the fiber guide direction P. The functional complementation of the aforementioned components of manufacturing apparatus 1 will be described in more detail below.

Individual fibers 2a, 2b spun into yarn 3 within the framework of the method are unwound, for example fiber bobbins, are spun together to form yarn 3 by fiber supply units 4a, 4b. Fibers 2a and 2b are supplied. The fibers 2a, 2b may also be referred to as slabs or playarns, or may be considered. In this exemplary embodiment, only two fiber supply units 4a, 4b are shown as mere examples. However, according to the principle described below, it may be optionally extended to three or more fiber supply units 4a, 4b, and as a result, it may be optionally extended to two or more fibers 2a, 2b. The number of fiber supply units 4a and 4b is determined according to the number of fibers 2a and 2b spun into the yarn 3 by this method.

The guide device 5 is configured to guide the supplied fibers 2a and 2b to the spinning device 6, and the spinning device 6 is arranged downstream of the guiding device 5 in the fiber guiding direction P. For this purpose, the guide device 5 is a plurality of guide elements 5a-5e arranged consecutively in the guide direction P of the fibers (five in each exemplary embodiment shown in the drawings). The fibers 2a and 2b to be guided can be guided from the first guide element 5a to further guide elements 5b to 5e arranged downstream thereof in the guide direction P of the fibers.

It is arranged immediately upstream of the spinning device 6 in the fiber guiding direction P. Appropriate support elements 7, for example, plate-shaped or disk-shaped, are provided between the guide elements 5a to 5e which are separated in the guide direction P of the fiber and are arranged one after another (immediately) in the guide direction of the fiber. The supporting element 7 may exert a desirable supporting action on the guided fibers 2a and 2b. In the exemplary embodiment shown in the figure, a suitable support element 7 is disposed, for example, between the first guide element 5a and the fiber supply units 4a, 4b.

Each guide element 5a-5e has a cylindrical or cylindrical geometric shape or basic shape. Therefore, these guide elements 5a-5e may be referred to as guide rollers or guide rolls, or cylinders, or may be considered. These guide elements 5a to 5e are rotatably attached around the axis of symmetry or the central axis of the guide elements 5a to 5e, and the guide elements 5a to 5e rotate around each of these axes of symmetry or the central axis. The motion is enabled to enable the guided motion of the fibers guided in the direction of the spinning device.

The individual, plurality, or all guide elements 5a-5e may be provided with a specific adhesive region or a specific adhesive surface (not shown) realized, for example by a rubber coating, on the fibers 2a, 2b. Due to the adhesive effect exerted, the adhesive region or the adhesive surface allows desirable guidance of the fibers 2a, 2b, i.e., with respect to the guidance direction P of the fibers, particularly unfavorable lateral directions of the fibers 2a, 2b. Prevents or prevents slipping.

Further, in the exemplary embodiments shown in FIGS. 1 and 3-the same applies to the exemplary embodiments shown in FIGS. 2 and 4-but of an unspecified traction device (optional). The traction elements (capacitors) 8a, 8b, 9a, 9b are shown. As a result, the fibers 2a and 2b can be supplied to the spinning apparatus 6 in a state where the pretension is generated by the traction of the fibers 2a and 2b, particularly by the longitudinal traction of the fibers 2a and 2b. In this case, the different traction elements 8a, 8b, 9a, 9b can incorporate different traction regions or different traction sections, eg, pre-draft and main draft sections, in the traction region or traction section. The fibers 2a and 2b receive different degrees of traction. These traction elements 8a, 8b, 9a, 9b may be traction elements that have been structurally modified specifically for the methods described herein and are required of the methods described herein. As such, it allows guidance or traction of fibers 2a, 2b.

The spinning device 6 is configured to spin the fibers 2a and 2b supplied by the guide device 5 together to form the yarn 3. For this purpose, the spinning device 6 comprises a spindle element or bobbin element 10, which is rotatably mounted around a spindle shaft or bobbin shaft (not shown). The thread 3 may be wound around a spindle element or a bobbin element. In the exemplary embodiment shown in the figure, a thread guide or thread monitoring device 16 is provided upstream of the spindle element or bobbin element 10.

As can be understood using these drawings, in the present manufacturing apparatus 1, the guide device 5 includes at least two individual guide elements 5d and 5e, and the guide elements 5d and 5e are connected to each other in at least one spatial direction. Are spatially separated from each other and are identified by the fact that the guide elements 5d and 5e can be used to supply at least two fibers 2a, 2b to the spinning device 6 or to the spinning device 6. To. It can be understood that these guide elements 5d, 5e are the last guide elements 5d, 5e before the spinning device 6 in the fiber guide direction P. These last guide elements 5d, 5e are arranged at the same level with respect to the spinning apparatus 6, but are laterally offset from each other (see in particular FIG. 3).

Using the manufacturing apparatus 1 shown in these drawings, it is possible to realize a method for manufacturing a yarn 3 having improved yarn characteristics formed by spinning two fibers 2a and 2b. An exemplary embodiment of such a method is described in more detail below.

In the first step of the method, the individual fibers 2a, 2b spun together to form the yarn 3 to be produced are supplied using the fiber supply units 4a, 4b.

In the second step of this method, the supplied fibers 2a and 2b are supplied to the spinning device 6 by using the guide device 5.

In the third step of the method, the fibers 2a and 2b supplied to the spinning device 6 are spun in the spinning device 6 to form the yarn 3 to be manufactured. Spinning of fibers 2a, 2b is performed in the spinning region 11 next to the last guide elements 5d, 5e. The manufactured yarn 3 is wound around a spindle element or a bobbin element 10.

According to this method, using two individual guide elements 5d and 5e, two fibers 2a and 2b spun into yarn 3 are supplied to the spinning apparatus 6, and the two individual guide elements 5d are supplied. It can be understood from these drawings that 5e are arranged so as to be spatially separated from each other in the spatial direction. In these drawings, the first fiber 2a spun to form the yarn 3 is fed to the spinning apparatus 6 using the first guide element 5d and together with the first fiber 2a to form the yarn 3. The second fiber 2b to be spun is supplied to the spinning apparatus 6 by using the second guide element 5e, and the second guide element 5e is arranged so as to be separated from the first guide element 5d. It is shown that.

Therefore, within the framework of the method, a guide device comprising at least two separate guide elements 5d, 5e is used, the guide elements 5d, 5e spatially with respect to each other in the spatial direction immediately prior to the spinning device 6. Arranged to be separated. As mentioned above, these guide elements 5d and 5e are arranged at the same level with respect to the spinning device 6, that is, at the same distance from the spinning device 6, while laterally oriented to each other. Arranged in a staggered manner. As described above, since the guide elements 5d, 5e have a cylindrical or cylindrical geometric shape or basic shape, in the exemplary embodiments shown in these drawings, these guide elements 5d, 5e They are arranged coaxially and spatially separated from each other in the direction of the central axes of the respective guide elements 5d, 5e, and thus in the spatial direction extending across the guide direction P of the fibers in a parallel arrangement. , Arranged so as to be spatially separated from each other. A pair of guide elements 5d, 5e arranged to be spatially separated from each other in a spatial direction extending across the guide direction P of the fiber are assigned to a particular spindle element or bobbin element 10. It may be referred to as a guide element or may be considered. Using the pair of guide elements, fibers 2a and 2b forming a thread 3 wound around each spindle element or bobbin element 10 are supplied.

The guide device 5 is provided by supplying fibers 2a and 2b which are spun together into yarn 3 by using two guide elements 5d and 5e which are arranged so as to be spatially separated from each other in the spatial direction. The free length L of the fibers 2a and 2b that are spun into yarn can be affected between the time of departure and the confluence 12 of the fibers in which the fibers 2a and 2b are combined, that is, in particular, the fibers. The free length L of 2a and 2b can be increased, which has a positive effect on the characteristics of the manufactured yarn 3 or the characteristics of the manufactured yarn 3. The increase in the free length L of these fibers 2a and 2b means that the fiber merging point 12 is further separated from the final guide elements 5d and 5e as compared with the conventional method, and as a result, the fibers This is due to the fact that the fiber confluence 12 is significantly closer to the spinning device 6.

The confluence point 12 of the fibers represents a part of a so-called spinning triangle. The merging point 12 of the fibers forms the apex of the spinning triangle facing the spinning device 6. Therefore, since the free lengths L of the fibers 2a and 2b forming the side surface of the spinning triangle increase as described above, the spinning triangle is "stretched" in the guiding direction P of the fibers, and thus the spinning triangle. The shape of the shape may be modified according to a method compared with the conventional method.

The angle α of the spinning triangle in the region of the apex facing the spinning device 6 is less than 90 °, especially less than 45 °, especially less than 30 °. Therefore, the angle between the fibers 2a and 2b after departure from the guide elements 5d and 5e is less than 90 °, particularly less than 45 °, and particularly less than 30 °. Therefore, the angle is an acute angle.

This method affects the free length L of the fibers 2a and 2b to be spun between the departure of the guide device 5, that is, the departure of the final guide elements 5d and 5e, and the confluence of the fibers 12. In particular, based on the discovery that by increasing the free length L of the fibers 2a, 2b, certain properties of the produced yarn 3 or of the produced yarn 3, particularly mechanical properties, can be obtained. ing. This is particularly due to the fact that the free length L of the fibers 2a, 2b to be spun increases (significantly) before the confluence of the fibers when compared to conventional methods. The (individual) fibers 2a, 2b may already be (significantly) twisted before the fiber confluence 12, which is the characteristic of the produced yarn 3 or the characteristic of the produced yarn 3. Has a positive effect on.

The free length L of each of the fibers 2a and 2b between the guide device 5 and the confluence 12 of the fibers in which the fibers 2a and 2b are bundled may be in the range of, for example, 4 to 20 cm, particularly. It may be in the range of 7.5 to 15 cm, preferably 10 cm.

The free length L'between the respective points 14 and 15 where the fibers 2a and 2b depart from the respective guide elements 5d and 5e in the direction of the fiber confluence 12 is, for example, in the range of 4 to 10 cm. It may be in the range of 5 to 9 cm, preferably 6 cm.

A spinning device 6 according to the present method is used, and the spindle element or bobbin element 10 of the spinning device 6 is arranged by the spatially separated arrangement of the guide elements 5d, 5e assigned to the guide direction P of the fiber. It can be understood from these drawings that the space 13 is arranged so as to be aligned with the space 13 formed between the guide elements 5d and 5e. Therefore, the spindle elements or bobbin elements 10 are arranged laterally offset (relative to the fiber guide direction P) in relation to the guide elements 5d, 5e assigned to them. In particular, the spindle element or bobbin element 10 is separated from the guide element in the guide direction of the fiber, while being arranged in the center between the guide elements assigned to the guide element.

Finally, in principle, additional fibers (broken lines) can also be guided using their respective final guide elements 5d, 5e, while these additional fibers (broken lines) are other spindle elements or bobbin elements (not shown). That is, it is usually supplied to the additional spindle element or bobbin element arranged parallel to the above-mentioned spindle element or bobbin element 10, that is, to the other spinning region of the spinning device 6, that is, the broken line in FIG.
