Description

Device for Winding an Elongate, Threadlike Element on a Winding Element

The present invention relates to a device for winding an element consisting of one or more elongated fibrous strands on a winding element, the device being rotatably driven about an inlet and a winding shaft for an elongated fibrous element. A frame having at least an element, the apparatus further comprising at least driving means for rotatably driving the winding element.

In the fiber or yarn industry, fibers or yarns (or generally elongated fibrous elements) are wound on a winding element, such as bobbin, for further processing. The elongate, threadlike element may consist of one or more strands. In certain applications, in the manufacture of single-stranded synthetic fibers, for example by extrusion processes used in the construction of sports fields such as artificial turf, it is desirable to unwind the fibers and twist them about their longitudinal axis.

In the case of single stranded elongated fibrous elements, this technique is called twisting. After the 'twist', the single stranded fiber is again wound onto the winding element. Multiple strands of elongated fibrous elements can also be wound about their longitudinal axis as described above. This technique is called twining.

Thus, the devices disclosed herein are suitable for handling single strands as well as plural (one or more) strands of elongated fibrous elements.

Not only does this method of producing twisted or knitted elongated fibrous elements require additional work, but it is also laborious because of the additional manufacturing time required for the twist / knit step after the winding step. In addition, the winding element on which a lot of synthetic fibers are wound thereon must be manually removed from the winding device and placed in a separate twist or knitting device. The latter work is time consuming and requires additional manual work, which is not attractive for economic and ergonomic reasons.

It is an object of the present invention to provide an apparatus as mentioned in the introduction which does not exhibit the above drawbacks. According to the invention, the winding device has a twisting means mounted in the framework, the twisting means imparting one or more rotations per unit length to the elongated fibrous element before the elongated fibrous element is wound around the winding element.

For a precise understanding of the device according to the invention, the term 'turns' refers to 'twists' (for single strands of elongated fibrous elements) or 'twines' (multiple strands of long strands). It should be recalled once again that in the case of fibrous elements).

Numerous additional work steps are omitted by performing a twisting or knitting operation before winding the elongated fibrous element (such as fibers or yarns). This not only shortens the manufacturing process of fibers or yarns, but also reduces process costs. The latter view is further supported by the fact that all sorts of additional, ergonomically less attractive manual work need not be performed.

In addition, since a separate twist or knitting device is no longer needed, a more compact structure is obtained by using the winding device according to the present invention.

The compact but highly functional structure of the winding device according to the invention comprises a twisting shaft in which the twisting means is rotatably driven by a drive means, the twisting axis being positioned in the framework with the first end of the twisting axis. It is mounted in a bearing in the framework in such a way that the other second end of the twist axis is located outside the framework. The drive means may be at least partially disposed outside the framework to rotatably drive the second end of the twisted shaft. This latter view assures that the winding device is easy to operate (cf. driving). The twisting means are easily accessible within the framework, for example for maintenance purposes, while the parts forming the fixed structure, such as the driving means, do not interfere with the optimum twisting or knitting operation of the twisting means.

In certain embodiments, the winding element may be mounted in a bearing on the winding shaft, which winding shaft is connected to the first end of the twist shaft through the bearing. In certain embodiments, the winding axis is arranged in line with the twist axis. This aspect ensures a dynamic freewheel or separation between the winding element and the winding axis on the one hand and between the winding axis and the twist axis on the other hand. This means that the winding axis moves freely within the framework and functions as a semi-fixed structure, on the one hand leading to a compact structure, while on the other hand this drive arrangement is one and the same for driving the axis. It guarantees the use of the drive unit.

In very specific embodiments, any number of turns (twist or knitting) per unit length can be added to the elongated fibrous element in a very efficient manner, with the winding device according to the invention, wherein the twisting means is provided on the first end of the twist axis. At least one radially extending twisting arm mounted to the twisting arm, the twisting arm having a feed-through channel for the elongated fibrous element, the feed-through channel of the twisting arm. It extends from the free end to the twist axis. The twist arm may be provided with a guide eye connected at its free end with a feedthrough channel.

More specifically, the feedthrough channel is a slot or bore formed on the surface of the squint arm, and the guide eye and / or feedthrough channel is provided with a material having enhanced hardness. In more detail, the guide eye and / or feedthrough channel is provided with a ceramic guide surface. On the one hand these properties help to control the yarn tension of the elongated fibrous element to prevent wear on the moving parts of the winding device according to the invention and on the other hand to prevent breakage of the yarn.

In certain embodiments, in order to obtain improved stability of the arm while the arm is rotating about the arm, the arm has a counterweight at the other end of the arm when viewed in the longitudinal direction of the arm. It is provided.

According to a further aspect, the twisting means by means of additional rotation (twist or knitting) per unit length, which can be effectively added to the elongated fibrous element, has a twist axis with a longitudinal bore, on the one hand It is connected to the feed-through channel formed in the twist arm, on the other hand is characterized in that it is connected to the winding bore formed on the winding axis.

In one particular embodiment, the bore is at a right angle near the connection with the feedthrough channel formed in the twist arm, and in that case the winding bore is also at the right angle. These points provide a smooth movement of the elongated fibrous element from the twisting arm through the bore in the twisting axis in the direction of the winding axis and the winding element present on the winding axis, without the risk of twisting tension above the permissible limit that can cause the yarn to break. Make sure.

According to the present invention, in order to reduce the occurrence of soft yarn breakage caused by wear, the bore in the twist axis is provided with friction reducing means, the friction reducing means comprising at least one ceramic guide surface in the bore.

One particular embodiment that provides a compact, lightweight but highly functional design of the present invention is characterized in that the winding shaft is provided with a support, on which the drive means for the winding element are arranged. The support is composed of a first support shaft connected to the winding shaft and a second support shaft pivotally connected to the first support shaft.

In the design of a very simple but reliable drive means for the winding element, the drive means comprises a driving roller rotatably mounted to a second supporting arm, the drive roller being a winding element. It may be located in the junction with the. As mentioned above, this method of driving the winding element for the purpose of winding the twisted and knitted long and elongated fibrous element not only provides a compact configuration but also is inexpensive.

According to the invention, an elongated fibrous element is accurately wound on the winding element, and a drive roller with a constant force adjustable by the power means in the winding element can be located in the junction with the winding element, the power means being a gas It may include a gas spring or a tension spring.

According to the invention, a rotatably driven guide roller, extending parallel to the drive roller, is mounted on the second support arm in order to securely wind the elongated fibrous element in the proper distribution over the entire length of the winding element. The guide roller is provided with a winding groove extending over its circumferential surface for carrying the elongated fibrous element to the winding element.

More specifically, a guide element extending in parallel with the guide roller is provided on the second support arm, and an elongated fibrous element can be carried in the direction of the guide roller above the guide element. Through the winding device, the possibility of clogging elongated fibrous elements or other transport problems is prevented in this way. The guide roller allows the winding to take place in a very uniform distribution over the winding element.

In a particular embodiment, the first end of the twisted shaft is provided with a circumferential tooth for driving the winding element through the drive roller, the tooth being guided through the one or more gear transmission during rotation of the twisted shaft. The roller is rotatably driven. This particular drive structure provides the winding and twisting means, the winding device mounted in a framework with no fixed structure, and the driving means for operating the winding device more efficiently.

In addition, according to these points, the structure is compact using only one driving means. As described above, the driving means is located outside the frame to drive the second end of the twisted shaft through a suitable belt or chain transmission, The specific bore structure used allows twisting of the yarns through the twist shaft and gear transmission. This also results in a robust and maintenance free structure.

In order to ensure flexible transport of twisted yarns or fibers in the device from the twist axis to the winding element, the support according to the invention is one for guiding the elongated fibrous element from the winding bore to the winding element through the guide element and the guide roller. The above guide wheel is provided.

According to the present invention, a guide means is provided on the support, in order to prevent the failure of the apparatus caused by the introduction of the elongated fibrous element into the framework and the resulting blockage or breakage of the yarn, the guide means being elongated from the inlet. It extends in the radial direction beyond the free end of the winding axis to carry the fibrous element to the twist arm beyond the winding element.

The winding device according to the present invention, for example, brings a drastic simplification of the manufacturing process of synthetic yarn. The apparatus may be directly included in the production line (directly connected to the back of the yarn manufacturing apparatus, such as an injection molding machine), and as a result, twisting and knitting of the yarn exiting the yarn manufacturing apparatus may occur directly. The yarn tension is easy to adjust by braking means on the arm and the inlet side, for example in the case of yarn breakage. This also leads to miniaturization of the winding device.

All particular parts of the winding device according to the invention are arranged around an axis 7, which is shown in FIG. 1, the first end 7a (not shown) of the axis 7. It extends into the interior of the framework 10, while the second end 7b of the shaft 7 is mounted to a bearing in the support girder 10a of the framework 10 in such a way as to extend out of the framework. have. The second end 7b of the shaft 7 is configured as a pulley, in which an annular carrier, for example a V-belt, can pass over it, the annular carrier being a drive means 2 Pass over the drive shaft of Said drive means 2 may for example be an electric motor which is connected to a fixed structure outside the framework 10 and imparts a rotational movement to the shaft 7 during the operation of the winding device according to the invention.

In addition, the winding shaft 6 may be mounted in the framework 10, and the winding element 5 may be mounted on the winding shaft 6. Elongated fibrous elements (for example twisted yarn or synthetic fibers) are wound on the winding element 5 with a large number of tufts 8.

Elongated fibrous elements (fibers or yarns) are introduced into the device 1 through the inlet opening 3. The inlet opening 3 is formed of support beams 4a-4b, which are pivotally mounted in the frame 10. It has a feed opening on one side to facilitate access to the components arranged inside and within the framework 10 for maintenance purposes or exchange of the elongated fibrous element 8 and the winding element 5 wound thereon. The support beam 4a provided with (3) is made rotatable.

2 is a detail view of the winding device and its associated parts according to the invention. 3A to 3F, the structure of the winding device is shown in terms of a plurality of different angles. The component of the winding device according to the invention is substantially a winding shaft 6 (FIGS. 3 a-3c), on which a winding element 5 can be mounted in a bearing. Thus, the winding element 5 is freely rotatable about the winding axis 6.

In order to ensure that the winding element 5 is securely mounted / supported on the winding shaft 6, the free end 6b of the winding shaft 6 is fixed with a nut or a shackle pin to secure the winding element ( 5) should not slip on the shaft.

An essential element of the invention is the possibility of imparting at least one rotation (twist or knitting) per unit length to the elongated fibrous element before the elongated fibrous element 8 is wound onto the winding element 5. According to the present invention, the winding device comprises at least one rotation (in the case of a single strand of elongated fibrous element) in the elongated fibrous element 8 (synthetic fiber or yarn) before the elongated fibrous element is wound onto the winding element 5. In the case of 'twist' or in the case of plural strands of elongated fibrous elements, twisting means are provided.

An essential element of the twisting means is a twist shaft 7 as already shown in FIGS. 1 and 2, the free end 7b of the shaft being rotated by a driving means such as an electric motor via a belt or pulley transmission. . The free rotation coupling 7c can be arranged between the twist shaft 7 and the belt pulley 7b.

The twist shaft 7 is mounted in a bearing in the girder 10a of the skeleton 10 (see FIG. 1) in such a way that the distal end 7a of the twist shaft 7 extends into the frame 10. The twist arm 11 is mounted to the first end 7a of the twist shaft 7, which extends radially from the twist shaft 7. The twist arm 11 includes a plate member 11b which functions as a counterweight with the free end 11a.

Since the twist shaft 7 is mounted in a bearing in the frame 10, when the twist shaft 7 is driven by the drive means 2, it will rotate like a radially extended twist arm 11. During operation, the twisting arm 11 rotates with the twisting axis 7 about the center of the twisting axis 7, the free end 11a of the twisting arm 11 being an elongated fibrous element. It is preferred that the tufts 8 of have a radius at least equal to or greater than the maximum radius formed by winding on the winding element 5.

In order to impart rotation (twist or knitting) to the elongate fibrous element, the fibrous element is introduced into the framework 10 through the inlet opening 3 (see FIG. 1) and the free end 11a of the twist arm 11. Haul in the direction of). As shown in detail in FIG. 4, the free end 11a is provided with a guide eye 12. In addition, the twist arm 11 is provided with a feed-through channel 13, wherein the feed-through channel 13 has a first end 7a of the twist shaft 7 with the twist arm 11 from the guide opening 12. Extend in the longitudinal direction toward the mounting position.

The elongated fibrous element introduced through the inlet opening passes through the framework 10, over the winding axis 6 / winding element 5, into the guide eye 12 and then through the feedthrough channel 13. It is conveyed in the direction of 7. During operation, the twisting arm 11 undergoes a rotational movement, which causes the elongated fibrous element carried through the inlet opening 3 and the guide opening 12 to be wound around the winding shaft 6.

Guide means 38a-38b are provided in the framework 10 to prevent the risk of a balloon of elongated fibrous elements formed as described above being caught behind various parts and leading to yarn damage. The guide means 38 (38b, see FIG. 3f) are arranged between the inlet opening 3 and the winding shaft 6 and extend in the radial direction beyond the free end 6b of the winding shaft 6. In this embodiment, the guide means 38a-38b are configured as a circular tube having a radius larger than the maximum radius at which the winding element 5 on which the tuft 8 is wound can be reached. More specifically, the outer radius of the guide rings 38a-38b is at least equal to the length of the twist arm 11, which is seen at least in the radial direction.

During the rotational movement that the twist arm 11 undergoes with the twist shaft 7, the elongated fibrous element is pulled over the guide ring 38a to prevent failure of the device and damage to the yarn.

Figure 3f shows another embodiment of the winding device according to the invention, in which two guide rings 38a-38b are used in place of one guide ring 38a, with each guide ring in the elongated fibrous element. The formation of balloons and the possibility of failure of the device and damage of the seals are avoided.

As shown in FIGS. 5A-5B, the fibrous element conveyed through the feedthrough channel 13 of the twist arm 11 through the guide opening 12 is passed through a bore 32 formed in the twist shaft 7. Is carried. In order to facilitate access from the vertically located feedthrough channel 13 (located on the twist arm 11) to the horizontally extending bore 32 in the first end 7a of the twist axis 7, The bore 32 is connected to the feedthrough channel 13 via a right angled portion 32a.

As clearly shown in FIGS. 5A and 5B, the first end 7a is freely and rotatably connected to the semi-fixed structure by a bearing 29, which semi-fixed structure is a flange of the winding element 6. And a support 18 (described later) including the support 35 and the support arms 18a and 18b.

According to this structure, the winding shaft 6 is freely rotatable in the frame 10 with respect to the twisting shaft 7.

As clearly shown in FIG. 5A, the flange 35 of the winding shaft 6 is also provided with a bore 32 and connected with the bore 32 at the position indicated by 32b. The bore 32 in the winding shaft 6 is also angled to the right so that the bore 33 opens toward the outlet opening 34, which exits the flange 35 of the winding shaft 6. It is formed on the outer surface. With respect to the rotating shaft 7, the winding shaft 6, the flange 35 and the supports 18, 18a to 18b are stationary (semi-fixed structure), so that additional rotation (twist or knitting) is seen. To the elongated fibrous element carried through 32. The elongated fibrous element exiting the outlet opening 34 comprises a large number of turns (twisted or knitted) per unit length and must be wound in a number of windings on the winding element 5.

Referring to FIGS. 3A, 3C, 3D and in more detail, FIG. 3F, before the elongated fibrous element is received in the winding groove of the guide roller 16 for the purpose of being wound on the winding element 5. The elongated fibrous element is conveyed to the guide element 17 via a plurality of guide wheels 19.

As such, the elongated fibrous yarn is bent in the shape of a pigtail passing out of the last guide wheel 19 and past the guide disk 39a of the yarn speed slackener in the direction of the eye 19 '. The guide disk 39a is provided with a groove (for example, a flat groove or a V-shaped groove) for accommodating an elongated fibrous element, and is formed by a rotating shaft (not shown) by magnetic coupling (not shown). Driven. The magnetic coupling works according to the eddy current principle. The shaft is carried through the burst speed smoother 39 and driven by the twist shaft 7 via the gear transmission 24, 25, 26 and the first gear transmission 21, 22, 23.

The guide disc 39a rotates in the transport direction of the elongated fibrous element. Using the appropriately selected transmission of the gear transmission and magnetic coupling described above, the speed of the rotating guide disk 39a is higher than the speed at which the elongated fibrous element is transported through the device. This allows the yarn rate gentler 39 to reduce any stretch present in the elongated fibrous element. For this reason, the hardness of the bobbin is maintained at a constant level. Very high yarn tension during the winding process results in rigid bobbins.

The guide roller 16 (see FIGS. 3b and 3f) has a spiral winding groove extending out of its outer surface, the groove being evenly wound over the entire length of the winding element 5. To act.

The drive means comprise a drive roller 15, which can be located in the junction with the winding element 5 to wind the elongated fibrous element onto the winding element 5. The force and the winding 8 (see FIGS. 2, 3b, 3c, 3e) that the drive roller 15 presses against the winding element are adjustable by, for example, a gas spring or a tension spring 20. .

The drive roller 15 and the guide roller 16, as well as the guide element 17, are mounted on a second support arm 18b, which pivots on the first support arm 18a. It is possibly connected. As already mentioned above, the support arm 18a is mounted in a bearing 29 on the first end 7a of the twist shaft 7.

The structure consisting of the support 18 (the first support 18a and the second support 18b) together with the drive roller 15, the guide roller 16 and the guide element 17 is a frame 10 in a free flow manner. ) Is mounted in. The winding shaft 6 can be mounted on the first support shaft 18 which functions in a semi-fixed structure via the flange 35. At its distal end, the first support shaft 18a is provided with a plurality of fixing openings 37 which function to receive the fixing pin 36 for connecting the winding shaft 6 to the first support arm 18a. . As clearly shown in FIGS. 5A and 5B, the winding element 5 is mounted in a bearing 30 on the winding shaft 6.

The driving of the drive roller 15 and the guide roller 16 for winding the elongated fibrous element on the winding element 5 takes place as follows. The first end 7a of the twisting shaft 7 is provided with a circumferential tooth 21 near the twisting arm 11 (see FIGS. 3B, 3D, 3F, 5A and 5B), and The gear belt 23 is arranged to drive the first gear 22 mounted on the first support arm 18a.

The gear belt is driven through various gear transmissions (see FIG. 3E), and the gear belt 28 is a driving roller gear 15a and a guide roller gear 16a (reference) for rotating the driving roller gear 15. : FIG. 3B, FIG. 3C, FIG. 3E) and the guide roller 16 are respectively driven. By means of an adjustable restraining force (force by the gas spring 20), the drive roller 15 is already present on the winding element 5 (and on the winding element) in order to rotate the winding element 5 on the bearing 30. To the wound yarn 8) (see FIGS. 5A and 5B).

The drive roller 15 pulls the elongated fibrous element through the device. The elongated fibrous element is introduced into the framework 10 via an inlet opening 3 and is conveyed in the direction of the twist arm 11, the twist arm being imparted in circular motion by a rotating twist shaft 7. The elongated fibrous element is transported over the guide rings 38a, 38b. The circular motion of the twist arm 11 makes a first contribution towards imparting a large number of turns (twist or knitting) to the elongated fibrous element per unit length.

The fibrous element passes through the guide eye 12 and is then carried through the bore 32 via the feedthrough channel 13 and the right angled bore portion 32a. The elongated fibrous element exits the bore 32 via the winding shaft bore 33 and the outlet opening 34 at the right angle. The outlet opening 34 forms part of the semi-fixed structure (composed of the winding shaft 6 with the flange 35, the first support arm 18a and the second support arm 18b), so that the bore 32 It does not rotate along the rotating twist axis 7 which imparts rotation (twisting or knitting) back to the elongated fibrous element within.

After the twisted, elongated fibrous element exits the outlet opening 34, it is wound on the winding element 5 by the drive roller 15 via the guide element 17 and the guide groove 16b of the guide roller 16. It is carried by a plurality of guide wheels 19 before winding on.

As clearly shown in FIG. 3D, the guide ring 38a is mounted on the first support arm 18a. In order to prevent the balloon of the elongated fibrous element formed by the twisting arm 11 against additional engagement, the elongated fibrous element in the direction of the twist axis 7 via the guide eye 12 and the feedthrough channel 13. The long elongated fibrous element may pass through the second guide ring 38b before is transported. When temporary instability occurs in the balloon with the use of the second guide ring 38b, the operation of the device is significantly improved because the elongated fibrous element is prevented from being entangled in the drive structure (rotational part).

In order to prevent abrasion of the fibrous element, the guide eye 12 and / or the feedthrough channel 13 may be provided with a material having an enhanced hardness. More specifically, the guide eye 12 and the feedthrough channel 13 may be provided with a ceramic contact surface. The feedthrough channel 13 is configured as a slot in FIG. 4, but may also be configured as a through bore in the twist arm 11.

7a and 7b show another aspect of the apparatus according to the invention. In this case, the device comprises a braking means 40 near the inlet opening 3, which brakes the inlet opening 3 so that the elongated fibrous element has a certain amount of internal extension tension. It serves to carry it to the winding / twist unit.

The braking means 40 are arranged on a support plate 46 mounted on the support beam 4a. The braking means 40 comprise a first braking unit consisting of three braking wheels 41, 42, 43. The brake wheels 41 and 43 are connected to the support plate 46 rotatably with respect to the fixing pins, and the third control wheel 42 is operable in the slot 46a formed in the support plate 46. It is provided. Since the position of the control wheel 42 in the slot 46a is adjustable, some constant internal twist tension is imparted to the elongated fibrous element as the elongated fibrous element passes through the guide wheels 41, 42, 43.

The tension in the elongated fibrous element is very important for the quality of the final twisted and wound elongated fibrous element and the operation of the winding / twist device. The control operation provided by the control wheels 41, 42, 43, which is applied to the elongated fibrous element passing by, is somewhat constant.

In addition, the control means 40 comprises a second control unit, which is composed of two rotatable reel elements 44, 45 arranged on top of the other, each reel element. 44 to 45 are provided with grooves 44 'and 45' formed on the circumferential surface. See also FIG. 7B.

The elongated fibrous element is introduced from the first control unit 41, 42, 43 into the parallel grooves 44 ′, 45 ′ of the two reel elements 44, 45 before being introduced into the apparatus through the inlet opening 3. It is wound several times and led. Preferably one of the reel elements, more specifically the reel element 44, is freely rotatable on a shaft 44a mounted on the support plate 46, while the other reel elements 45 likewise have a shaft 45a. Rotatable in this case, the rotation of the reel element 45 is braked by the magnetic brake 51.

This is in contrast to the reel element 44 being able to rotate freely about its axis 44a. The magnetic brake 51 operating according to the eddy current principle is present in the tufts wound in the grooves 45 'and 44' when the elongated fibrous element is slid from the reel element 45 in the direction of the inlet opening 3. The elongated fibrous element is decelerated to allow adjustment of the internal yarn tension.

The control means may also consist of a speed-dependent hysteresis brake, ie a control action that depends on the number of revolutions of the device. The higher the rotation speed, the greater is the action of the brake 51 acting on the elongated fibrous element passing laterally. As such, a more stable balloon is obtained over the entire speed range of the device. The offset and magnitude of the control action is adjustable.

8 shows another embodiment of the twist axis 7a. In this figure, a bore 32 penetrating through the twist axis 7a is provided as a friction reducing means, and in this embodiment in the form of ceramic rings 61a and 61b, the ceramic ring has a long elongated fibrous element passing laterally. Functions as a guide surface for In addition, the ceramic guide rings 60a, 60b are arranged on the one hand near the transition point 32a between the feedthrough channel 13 and the bore 32 in the twist arm 11, and on the other hand the bore 7a. And near the transition point 32b between and the winding bore 34. This prevents the wear and damage of elongated fibrous elements.

It will be appreciated that by using such a structure, a precise winding device is obtained, and as a result of the combination of the twisting means and the winding means, a simple and compact device capable of twisting (or knitting) as well as winding is obtained.

The number of turns (twist or knitting) per unit length in the elongate fibrous element depends not only on the rotational speed of the twisting arm 11 and the twisting shaft 7 but also on the winding speed imparted by the drive roller 15. In theory, the rotational speed of the twisting arm 11 and the twisting shaft 7 is directly determined by the rotational speed of the twisting shaft 7 imparted by the drive means 2. The speed at which the elongated fibrous element is conveyed through the device according to the invention is determined by the rotational speed of the drive roller 15, which is determined by selecting the correct transport rate for the gear belt. The winding device according to the invention makes it possible to give the elongated fibrous element 35 ± 2 S- or Z-turns (twist or knitting) per straight length (meter).

However, the number of S- or Z-turns (twist or knitting) in the elongated fibrous element can be freely adjusted during winding when using the device according to the invention.

Combination of twist / knitting and winding in one device can significantly increase the yield of twisted or knitted twisted yarn or synthetic fibers, which has significant improvements in terms of productivity and production capacity as well as pay-off periods. To come.

The number of turns (S- or Z-twist or knitting) and the speed at which the winding occurs are not interdependent.
