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.

This year’s show attracted a large number of visitors. SSM as one of around 1'700 exhibitors from 28 countries and economies could impress the visitors by showing a wide range of applications and latest technology solutions to help textile producers to become more competitive.

For the first time ever, SSM presented their brand new drum winder with lowest power consumption per spindle. The small pitch and integrated control cabinet maximize the space utilization. Thanks to the new developed and single controlled motor, it is the ideal machine for an energy efficient rewinding of cones used in the weaving, warp knitting and circular knitting process.

Undoubtedly the air texturing machine from SSM attracted the largest attention. Benefitting a wider range of applications, such as fancyflex™ options for the production of slubs and thick & thin effects. Besides of this, several new product launches had been introduced to the public as well.

SSM would like to take this opportunity to thank everybody who visited the booth and is looking forward to future partnerships and collaborations.

The exhibitions in Colombia, Bangladesh, Russia, Indonesia and Pakistan took place on joint booths of the SSM representatives. During the shows, SSM met many existing, and also potential new customers that showed interest in their products. Thanks to the great effort and support of the SSM agents the exhibitions have been a great success.

For Japan Yarn Fair and Saigontex, SSM had their own booth with the kind support of their local representatives. There, the main focus was given to the high range of possibilities SSM customers could profit. With final packages, wound on SSM machines, as well as knitted textile samples the visitors could feel the difference.

The biggest appearance of SSM was at the ITM in Istanbul, where they combined the sample bobbins & textile (made on the TG30-ETC) with the winding and yarn process machines, such as DP5-T for creating slubs and neps, the XENO-AC for air covered yarns or the XENO winding and doubling machines including DIGICONE® 2 for higher dyeable package densities. Last but not least the PWX-MTC, SSM’s latest machine for rewinding of highly elastic yarns on muffs or hanks, had been showed.

Over all SSM had a successful appearance on the shows around the globe in the first four month and they are looking forward to the exhibitions to come, in order to serve the market with their latest and best solutions for the textile industry.

Until then, detailed information about their textile machines with leading technology is available on SSMs webpage.

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 spinning operation comprises six spinning mills having 225,000 spindles. A wide variety of yarns are produced in these mills. The spinning mills annually produce approx. 42’000 tons of yarn. In their twisting set up they have 100 TFO machines with a daily production of approx. 66’543 kg. Main count range is Ne 6/2 to 80/2. So far, Indus Group is working with around 600 spindles of SSM assembly winding machines: CW1-D, TW2-D and the latest TWX-D

To find out what impact the SSM machines had on their success, MAKVIZ (SSM agent) have interviewed Mian Shahwaiz Ahmed (one of the owners):

What made you believe that SSM AG was the best for achieving your desired result?

In 2005 we bought the first machine CW1-D assembly winder from SSM AG. Since it is a drum winder we didn’t get many extra benefits comparing to other options available in the market, however we found the best after sales service and support from SSM. Later on we bought some Japanese and Indian assembly winders which were not as good as the SSM drum winder machines.

In 2014 MAKVIZ came up with the new idea of knot-free packages on same size TFO pot. We bought the first TW2-D precision assembly winder from SSM and surprisingly with the help of the precision winder we got knot free package which helped us to improve the efficiency of our TFO machines and eliminated our major complaint of twist variation due to knots/splices.

Having this experience we bought seven SSM precision assembly winders (TW2-D / TWX-D) within our group up till now.

How did you find the machine/service of SSM and are you happy with the completed job?

With no second thought, SSM manufactures the most eligible machine to perform the desired job and we enjoy the best after sales services from SSM compared to any other supplier in the world.

Would you extend your production with SSM machines and recommend them to a friend?

We are in process to replace our old winders and SSM’ precision winders are our first and only choice, since we are proud to have the SSM brand in our production facility. We are already recommending SSM precision winders to other textile companies.

What are the two most significant improvements that have resulted from work with SSM AG?

We are able to achieve approximately 25-30% more weight on the same package dimensions, with the help of SSM precision winders, compared to random wound package. We are running SSM’s new model TWX-D at highest speed without any yarn breaks, due to proper tension control on all spindles, which helps to gain higher efficiency on the TFO process.

Mission statement of Indus group

We aim to provide superior products, financial security, high performance and quality services that fully meet the needs of our customers and maintain the financial strength of our company. We invite our valued Clients to come and see us how beautifully we are doing all this.

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.

At the ShanghaiTex 2013 SSM has introduced the x-view™ density analysis. Since then the state of the art method was used for further improvements of SSM’s winding technology for the benefit of their customers.

The first part of the density analysis is performed on an industrial x-ray CT (XRCT) scanner. Here the yarn package is digitally x-rayed from several directions. These recordings are then calculated for a three dimensional computer model of the yarn package. The computer model serves as raw-data source for the final analysis. Several cross sections are measured to form the mean density profile of the examined package. The density analysis with an XRCT scanner allows finding fine-tuned winding recipes for specific requirements. Furthermore it enables SSM to steadily improve their winding technology or to create customized yarn packages. With its customers in mind, SSM is in contact with material testing labs to make the x-view™ analysis better available.

Thanks to the commitment to technological innovation, focused on cooperation with best partners in the field and with industry leaders, nowadays SSM is recognized as innovative leader in Yarn Processing and Winding – Swiss developer, leader and inventor of the electronic yarn traverse system.
