Until now, searching for fully automatic finish winders for sewing thread on the market has proved futile. The variety of yarns to be processed is too large and there are too many different tube dimensions and applications: This makes it impossible to produce a standardized design for a fully automatic machine, meaning that an extremely costly custom machine would be the customer’s only option. But this does not mean that machines on which the tubes are changed manually are the best solution in the sewing thread sector.

Sewing thread producers still use many older machines that require a lot of manual intervention because these machines are primarily what a large proportion of winding machine manufacturers offer. A few manufacturers do produce semi-automated machines as well, but only SSM finish winders offer reliable, efficiency-boosting functions such as length measurement, tuck-in, automatic changing of full packages, and package winding. This is crucial because with sewing thread, the decisive factors are above all its appearance, the winding, and the unwinding characteristics of the sewing thread package in the subsequent process. The machines in the SSM TK2-20 series are real profit makers in this regard. They are proven to be a reliable piece of equipment for meeting the high requirements of SSM customers in the sewing thread industry.

For these reasons, an Asian sewing thread producer decided to replace its “manual machines” with a 284-spindle SSM TK2-20-TT. This enabled the company to increase its production capacity by 100 tons per month to reach its target of 300 tons per month. And that’s not all: At the same time, it was possible to reduce the number of production spindles required by 50 spindles and reduce the number of personnel needed to operate the entire system by around 60%. The labor costs alone could be decreased by around CHF 30 000 per year thanks to the investment – which is especially impressive since the company is in a newly industrialized country.

As the machines had already paid for themselves after just 14 months, the customer is earning an extra CHF 150 000 per year thanks to the very precise length measurement and the lower power consumption of the entire TK2-20-TT system.

Fancy intermingling option
This option creates commingled yarn with fancy color effects. It is available for the DP5-T, making this machine even more versatile, and for the new SSM air-covering machine, the XENO-AC. It consists of a high-speed valve attached to an intermingling jet body that stops and restarts the air flow at a very high pace.

The principle is not new, but its availability on SSM single- position machines makes it much more attractive for users. Intermingled fancy yarns are generally produced in small to medium lot sizes. There is no need to dedicate a complete machine side for producing a small quantity, rather, only the necessary positions are used, which gives users the added flexibility they want.

Several types of fancy effects can be combined, for instance slub and VARIO, to produce even more complex design effects. Slubs in conjunction with VARIO effects can also be combined with the elastane feeding device to produce elastic air-textured yarns. The whole range of SSM devices and options allows for new types of designs, directly at the yarn stage, making the downstream processes (weaving, knitting) simpler and giving yarn producers powerful means of diversifying their offer and enhancing their competitiveness.

Part 3: High-speed valve option
Another option available on the SSM air-texturing machine is the so-called high-speed valve, which can completely stop the air supply for a defined interval. This specially designed high-speed electro-valve is installed at the compressed air input, before the texturing jet. It allows creating a new kind of fancy effect in which the ATY shows successive non-textured lengths contrasting with the duller textured lengths, giving the appearance of shiny flashes. When texturizing threads of different colors together, the air interruption makes for a color-change effect, showing one or the other color in an alternating sequence.

Part 4: fancyflex™ AIR option
Since one aim of air texturing is to create imitation of natural fibers, the fancyflex™ AIR option was developed to imitate the natural irregularities shown by linen, silk and other yarns. This option works by producing neps and texture variations present in natural yarns but using inexpensive materials like polyester. Our fancyflex™ VARIO option combined with a torque jet to false twist the threads offers users a new type of fancy effect. This setup is a way to easily control the characteristics of the effect. The prominence of the neps and the distance between them can be controlled in order to achieve the desired effect in the fabric.

fancyflex™ VARIO
In order to be able to create longer effects and new kinds of effects, SSM developed a new device: the fancyflex™ VARIO. Featuring hardware and software specially developed in house, it provides controlled speed disturbances directly to the overfeeding godets, which are perfectly synchronized.

By controlling and changing the overfeed of a single component of a yarn, users can change the resulting dullness and also the final color of the ATY. Used on a single-color ATY, lengths with higher overfeed, which appear duller, will be produced along with lengths with lower overfeed, which appear shinier. Used on a single black or white thread, the shade of the yarn can be changed from darker to lighter – slowly changing, producing a shading effect or a 3D effect. When VARIO is used on several threads of different color, several colors and shades can be produced for a single air-textured yarn.

The fancy effects shown beside were created using a rather simple two-step cycle with two different overfeed levels, some with a random time setting.

To further support users in developing unique fancy effects, SSM developed the pattern mode. It provides a sequence of up to 50 different steps. The overfeed level and duration can be set for each step, allowing the creation of special repeating patterns.

fancyflex™ III slub device: slub effect at its best
SSM has refined and expanded the capability of the slub device. It can now handle two different yarns e.g. different colors resulting in an ATY showing successive slubs of two different colors or sizes. Proper dispatching of the slubs in the woven fabric is critical because this plays an integral role in the final visual effect. If the distance between slubs does not vary enough, an unwanted pattern on the woven or knitted fabric will result. To solve this problem, the cycle time of SSM slub device constantly and automatically changes by an adjustable random factor of up to 100%.

To give yarn manufacturers full control of slub distribution, SSM created the so-called “pattern mode.” It allows users to control the distance variation by editing a sequence of up to 40 steps, or so up to 40 consecutive slubs, that will repeat in a loop, allowing full control of the final fabric design. The pattern mode also gives greater flexibility when processing two colors of slubs because the user can choose which color to use for each of the 40 steps.

This powerful mode of control opens the door to specific designs that are not possible using the more conventional random mode, like slub degrade, which progressively increases or decreases the distance between slubs.

The maximum length of the slub is limited by the fancyflex™ III slub device, as it can only accumulate a certain quantity of yarn before it must be released.

Among other factors, such as digitens™ (SSM online regulated yarn tension) and DIGICONE® 2 (SSM step precision winding), the backpressure force is a very important influencing factor for a perfect yarn package construction on a winding machine. The backpressure force has a significant influence on the package density that needs to be achieved. The more precise a backpressure force system is working, the better the density can be controlled, resulting in an optimal package construction. Standard backpressure force systems, such as pneumatical-, electro-mechanical- or mechanical systems, on winding machines worldwide follow a pre-defined curve. Disturbing factors, which can occur frequently in a production, are not corrected with these systems.

Therefore, SSM has developed the world’s first backpressure force system that constantly regulates the contact force and consistently bypasses disruptive factors.

preciforce™ - A worldwide unique backpressure system
preciforce™ is the first and only backpressure system on a winding machine which regulates the contact force in a range of 200 – 8’000 cN with precise accuracy, regardless of whether hard- or soft-packages are wound. Due to the innovative design, no manual backpressure adjustments, commonly known on winding machines with pneumatical or mechanical backpressure systems, are any longer required. Thanks to the compact design, the powerful preciforce™ system can easily be retrofitted on existing SSM XENO winding machines of all types.

Besides of all these benefits, the preciforce™ system is entirely maintenance free, consumes less energy and the fact that the system is self-calibrating further enhances the advantages of the preciforce™ system.

The SSM preciforce™ is optional available for SSM XENO-YW, -YD, -PB and -AC machines.

The variety of yarns and packages – a particular challenge
The problem is: the winding machines often fail to instantly wind packages that can be easily dyed. This is due to the fact that there are thick yarns, thin yarns, rough yarns, smooth yarns, straight packages, conical packages … the list could be continued infinitely. Good winding machines must take into account all these parameters and, at the same time, constantly produce packages of high quality. In case a package is wound in a suboptimal way, this situation will lead to problems in the downstream processes and, as a consequence, result in additional disadvantages. Additional disadvantages, however, cost time and money – money that is often lacking in the highly competitive textile market. Therefore SSM has developed an algorithm, in cooperation with a renowned university, enabling the winding machines to wind the “perfect” package, regardless of the yarn.

Images instead of laboratory tests
The engineers and mathematicians opted for a special approach. Instead of measuring parameters such as yarn tension, density, material, or yarn diameter, and packing them in complicated formulas, they translated the SSM expert knowledge into a theory, allowing for a precise prediction of package structures and density distribution. Using methods from the number theory, they finally managed to get a grip on the “chaotic and dynamic system” of package winding.

Based on the calculations, it was possible to devise the DIGICONE®2 algorithm that can be directly implemented into the winding machine control software. By means of high-speed recordings during the winding process and with the aid of x-ray computed tomography, the success of the SSM project was finally confirmed (see image comparative spool). Result: the identically constructed machines, which previously were not always able to wind a package that can be easily dyed, accomplished this task straight-away with the new software.

Competitive advantage through innovation
Thanks to the cooperation between SSM and university, the idea could be optimally implemented. “The innovative DIGICONE®2 algorithm enables us to stand our ground in the competition with other winding machine manufacturers”, says Karaarslan. The algorithm is successfully used by the latest SSM machine generation, and many customers have already tangibly profited from it.

What’s a stable electricity supply?

An electricity supply is characterized by frequency, magnitude, waveform and symmetry of the three-phase-voltages. If the following disturbances exceed certain limits then the quality will be affected:

• main power shortages
• jitter light
• voltage variations
• frequency variations
• slow and rapid voltage changes (over-voltage, spikes)
• unbalance of three phase voltage
• harmonic distortion

An exact definition of a stable supply is given in the European Norm (ex. EN50160). SSM assures its machine function correctly if the norm is fulfilled.

How to test the electricity supply

To test if a supply is inside the norm you have to analyse your net over a long time. Variations over the seasons have to be taken into consideration (summer/winter influences etc.). Often a weekly analyse will give you sufficient information about your net. SSM can offer a short analyse of your net. Very often though consumers know their supply. Important are the amount of main power shortages and voltage variations.

How to connect the machine to the supply

A lot of errors can be avoided by connecting a machine correctly:

• Is the grounding system of the machine correct?
• Sufficient cross section of the supply pipe?
• Avoid connecting machines of different power classes to the same main distributor.

How to protect a machine

There are a number of devices that can help to protect a machine, e.g. UPS (unbreakable power interrupt), power stabiliser, flash protector, or net filter. It is important to choose the best and most economical solution. The beside checklist will help you to choose appropriate equipment.

The ratio between double strokes and number of revolutions is kept constant for a certain diameter range. The crossing angle varies only slightly within a range of ±1°. This results in an enhanced package density that does not change with increasing package diameter. So the building of pattern zones is avoided and the package maintains a stable structure without any ribbons. Due to this stable structure, the risk of complete layers “slipping off” during the unwinding process of dyed packages, as known with random winding, is completely eliminated.

The introduction of the XENO platform opened new possibilities for optimizing the winding algorithm. Thanks to this new machine platform, SSM could release DIGICONE® 2, enabling an increase of dye package density by another 10–24% with unchanged dyeing recipes.
