Autoconer X5 – Ready, steady, go! How you can master all textile challenges The varied textile requirements and customer requests that crop up in day-to-day work in the spinning mill are the challenges you encounter when testing your strength against your competitors. With its new Autoconer X5, Oerlikon Schlafhorst will get you fit for the race for pole position in the textile market.

1. Groundbreaking high quality

Once again we have focused on the latest trends in the textile industry in the further development of our winding machine and have integrated solutions and performance features that enable you to face the many challenges successfully.

Quality, productivity and the consumption of resources are important cornerstones of every textile company. They are the parameters by which your customers judge your performance and the basis on which you yourself secure their efficiency and profitability. This is why we have made the Autoconer X5 even stronger in these areas.

PreciFX, the world’s only drumless yarn traversing system both for processing bobbins and rewinding packages, sets entirely new standards when it comes to package quality. With a pattern-free package structure, individual package design, package characteristics that can be ideally adapted to downstream processing and the freedom to choose between the winding technologies of random wind, precision winding and step precision winding, you can satisfy every whim of your demanding circle of customers. Speedster FX is a new system for influencing the yarn balloon when separating the yarn from the bobbin to reduce yarn tension peaks and to reduce the increase in yarn tension. As a result, your yarn is under less stress during the winding process. This is reflected in the excellent yarn quality.

When redesigning the Autoconer X5, we took special account of current challenges with regard to greater automation and extensive flexibility of the production programme. You are thus equipped for the contest. With the Autoconer X5, you are equal to all challenges and occupy the lead position at all events.

Speedster FX creates the prerequisites for higher productivity X-Change doffer: new and with faster package doffing PreciFX generates process and productivity advantages Central settings ensure a rapid start-up Greater dynamism thanks to single motor drives

The cleverly conceived functionality of Speedster FX means that you can achieve a noticeable increase in productivity depending on a few influencing factors such as material, bobbin shape, and winding parameters. Speedster FX reduces the load on the yarn precisely in the important final third of the bobbin. Your Autoconer X5 produces for you, therefore, at the maximum speed depending on the yarn and so you utilize your production potential to the full. The new X-Change doffer has upped the tempo considerably both with regard to its travel speed and in the package doffing cycle. Smart functional details such as central setting of the doffing parameters, automatic lot changing without manual intervention, monitoring of the doffing process for success and changeovers to new type of packages in the minimum of time make this a valuable pacemaker on the Autoconer X5 in every respect. PreciFX offers productivity advantages during the winding process due to the extended scope when combining winding parameters. And you can pass on productivity advantages to your customers, because PreciFX packages feature convincing improvements in unwinding properties and offer opportunities for shortening process sequences.

X-Change doffer for clever package handling and swift processes New central settings: 1 x setting with multiple benefits

Targeted automation of process sequences is coming increasingly to the fore in the textile industry, even in countries where virtually all processing has been manual previously. The Autoconer offers various approaches to process automation. On type RM machines, the doffer plays a key role as an automation unit. In combination with the newly designed superstructure and optimized cycle sequences, the new X-Change doffer makes full use of its functionality with regard to automation. Manual intervention is no longer necessary when changing the package type, or when winding on a new lot including feed change. The tubes can operate entirely independently and can process different types of tube without any mechanical settings being required. If an empty tube is missing for the package doffing about to take place, the doffer procures one for itself from the neighbouring winding unit. If a bobbin doffing cycle takes place in parallel during package doffing, then the new yarn can be passed on to the doffer directly from underneath thanks to the new cycle. Red light events and waiting times during package doffing are dramatically reduced. The X-Change doffer is a reliable, independently operating assistant to your staff, automating your production sequences with a host of interesting details.

Piecing cycles controlled by sensor and single motors to minimize waste and energy and optimize piecing times Time- and labour-saving process sequences Energy-optimized cooling concept with a new design

No matter whether it’s time, staff, energy or raw materials, we know that all resources are only available to a finite extent. The focus has often been, and still is, on productivity-oriented value creation. But in the last few years of rising raw material and labour costs especially, there has been a change of course towards resource-conscious process configuration. The Autoconer 5 was already on the right track with its optimized piecing cycles, innovative design, sensormonitored process sequences and interactive user guidance. For the Autoconer X5, therefore, it was only necessary to work on the fine-tuning relative to resource utilization. The potential comprises several layers: further simplification of the operating procedure through central settings and a “learning mode” for the doffer; short, time-saving paths (central energy and operating unit, i.e. Informator operation and yarn chamber emptying all in one location); elimination of manual handling due to newly designed superstructure. One secondary effect of redesigning the central energy unit was to improve cooling of the electrical components, making them more reliable. Thanks to individual package design, PreciFX offers an opportunity to reduce transport and process costs and shorten process chains in a manner that makes economic sense. The sum total of many deliberately designed features provides the performance boost for the Autoconer X5.

Biconical packages with PreciFX Package design for greater efficiency in downstream processing As already described in recent issues of the Oerlikon Schlafhorst Express, PreciFX, the unique drumless yarn traversing system of the Autoconer, offers entirely new possibilities for individual package design. Its software-controlled yarn traversing offers the maximum freedom to convert technological knowledge directly into package structures that meet the requirements, both in the package build and in process configuration. This time we want to highlight the production of biconical packages as a completely new application. Biconical packages in themselves are no technological novelty, but the possibility of producing such package formats of individual design directly during winding from the bobbin onto the package is entirely innovative and unique, thanks to PreciFX. Technological advantages resulting from the biconical package build The application utilizes the realization that the yarn break rates when smaller packages (traverse 3”, 4”) are lower than when unwinding 6” packages. It is also known that unwinding problems tend to occur in the larger diameter range, depending on e.g. fibre material or package build. On the basis of this knowledge it was an obvious idea to reduce the traverse in the larger package diameter in the build of hard packages, i.e. to design a biconical flank structure. The aim is to improve the unwinding properties for large package diameters and/or increase the running length per package. This can yield efficiency increases for warping and weaving in particular.

(3.5gg) in the basic build of the package and then even increasing the number of groove turns as the traversing became narrower. The result is that virtually the same package weight is achieved with the same diameter for the biconical packages. The second trend, towards enlarging the package diameter, is justified in that, thanks to the biconical format, no unwinding problems are to be expected in the larger diameter. These unwinding interruptions were previously the limiting factor on the maximum diameter. Very successful biconical packages were then produced, therefore, with a larger package diameter and greater package weight (e.g. 1.5 kg (biconical) compared to 1 kg (drum)) without having to make trade-offs with regard to the yarn break rate in the warping creel. On the contrary, the unwinding speed in the warping creel could even be increased. Economic advantage Thanks to the adaptation of the package format to the special conditions of package take-up, better unwinding behaviour could be observed in various warping creel tests. Higher efficiency ratings can thus be achieved in warping. If it is then possible to increase the package diameter of biconical packages, the potential for increasing economic efficiency is raised still further.

Package design – individual and intelligent The package is wound up to an selectable diameter with a 150 mm traverse (6” displacement), then the traverse is shortened linearly up to the final diameter. The final traverse – likewise freely selectable – lies in a range between e.g. 90 – 120 mm. Software-controlled yarn traversing with PreciFX permits individual configuration of the respective package format, such as e.g. settings of the diameter from which traverse shortening is to take place, how pronounced the traverse shortening is to be and in the case of tapered packages even different angle of the left and right flank. The final forming of the inner package structure of biconical packages and the final package format are then designed on the basis of downstream processing requirements. 2 trends are to be observed here. On the one hand, the desire was expressed in the practical trials to retain the previously wound package diameter even for the biconical packages, with virtually the same yarn running length. This problem was solved by winding with a very high number of groove turns

A wide variety of biconical packages.

Speedster FX – an attractive new module in the FX series Opt for high productivity and yarn quality Take-off of the yarn from the bobbin, with its special physical and technological features, is of fundamental importance for the winding process. Oerlikon Schlafhorst has once again looked at this aspect in greater detail and has implemented the knowledge gained in this process in the functional design of a new technology module, the Speedster FX. The aim was to influence the yarn balloon on separation of the yarn in such a way that productivity and quality advantages are yielded. The challenge in this case is not only to reduce the yarn balloon but also to shape it in the optimum manner technologically. Speedster FX forms the balloon throughout the unwinding of the bobbin The special form and functionality of Speedster FX makes it possible to utilize the advantages of balloon formation for separating the yarn and at the same time to eliminate the development of negative centrifugal force that stresses the yarn and has an adverse effect on unwinding behaviour. With Speedster FX, the new system for influencing the balloon, you shape the yarn balloon actively throughout the unwinding of the bobbin. Sensor control ensures that Speedster FX is always in exactly the right place, so that the yarn is always removed from the bobbin at the perfect angle. The unwinding yarn swings off freely without coming into contact with the yarn layers on the bobbin or the tube surface. During the development of Speedster FX, particular attention was paid to the fact that the load on the yarn caused by unwinding increases sharply especially in the last third of yarn unwinding. Conventional rigid or mobile balloon control systems reach their limits here and arrest their functional effect prior to this. Not the Speedster FX: it’s in action from the first to the last centimetre of yarn. The result: it reduces the increase in tension precisely in the last third of bobbin unwinding in a particularly effective yet gentle manner, thereby considerably lessening the stress on the yarn.

Technological advantages thanks to Speedster FX The tension characteristics of the bobbins no longer play any real role. The yarn tension is reduced to a minimum and yarn tension peaks caused previously by varying balloon forms are evened out demonstrably during the entire yarn take-off. Tension breaks and problems with layers sloughing off are significantly minimised, resulting in a perceptible increase in process stability. Speedster FX and Autotense FX also complement one another perfectly on the Autoconer! The unique online yarn tension control system Autotense FX controls the yarn tension precisely in cN. The reduction in tension achieved by Speedster FX especially in the final third of the bobbin enables Autotense FX to operate even more effectively. Throttling of the speed using Autospeed is only necessary, if at all, at a much later point. This facilitates highly productive processing of bobbins of every type and characteristic. Your advantages with Speedster FX The unwinding behaviour of the yarn on the bobbin depends on many factors: • • •

the bobbin feed the yarn type the winding parameters, depending inter alia on downstream use of the packages

Due to this, the advantages generated by Speedster FX are very varied in nature. Positive effects can be achieved in practice both with regard to increased productivity and improved yarn quality.

Thanks to sensor control, Speedster FX acts in the right place throughout unwinding of the bobbin.

Top speed over the entire line with Speedster FX

Guarantee or enhance yarn quality

The mode of operation of Speedster FX in maintaining an even yarn tension level and minimizing the yarn tensile strength – especially in the last third of bobbin unwinding – offers the opportunity to increase productivity markedly without negatively influencing the yarn quality. Opportunities arise thanks to: • • •

Winding at a yarn-dependent maximum speed, i.e. directly increasing the winding speed that can be set Increasing the average winding speed (reduction in the amount of Autospeed reduction) Reduction in yarn breaks caused by tension at high winding speeds (achieving a higher efficiency rating)

On the basis of our practical experience, productivity advantages are yielded especially in the manufacture of dye packages, when processing coarser yarns (balloon formation), in the case of bobbins with a greater tube length, and in applications where it was necessary previously to carry out winding at a lower yarn tension (steamed bobbins, soft-twist yarns).

Our findings show that when winding using Speedster FX at a comparable winding speed to the previous winding process, the yarn quality, in particular the total IPI values, are improved. This offers two options for your process configuration. You can achieve better yarn quality with the same productivity and pass this on to your customers. If your yarn quality is already adequate for your requirements, you can increase the winding speed and still attain the previous yarn quality level, i.e. you have enormous potential for productivity gains without sacrificing quality. Further quality advantages can be gained by using the optional bobbin dust removal feature, because this is directly linked to the Speedster FX. Thanks to the sensor control this too is always in exactly the place where the fibre fly arises during yarn unwinding (at the bobbin taper, taking-off the yarn from the yarn structure). Based on your requirements you can work out the balance between maximum productivity and high yarn quality using Speedster FX. Optimize your winding process to meet customer demands and their process prerequisites.

Oerlikon Schlafhorst takes the lead in major project in Ethiopia Spinning and weaving project of Kombolcha Textile Share Company (Ethiopia) The know-how of Oerlikon Schlafhorst as a strong, reliable and experienced project management partner is in demand worldwide. The Kombolcha Textile Share Company (Ethiopia) has opted for Oerlikon Schlafhorst, therefore, as the lead partner in realising its modernisation project. The first request for planning a major spinning and weaving mill project was made in July 2008. After clarifying important details such as the required production capacity, the desired performance features and the necessary process modules, the project department of Oerlikon Schlafhorst, working with proven consortium partners LTG, Trützschler GmbH & Co. KG and Sohler-Neuenhauser GmbH & Co. KG, submitted a convincing overall package. The contract was signed in Addis Abeba in February 2009. All stages were discussed with the customer, from the concept to the turnkey solution. For Kombolcha Textile Share Company (Ethiopia), integrated project management of this kind means that "the whole is more than the sum of its parts”, because all partners together seek optimum coordination, synergies and overlapping concepts.

frames, 11 ring spinning machines and 2 rotor spinning machines by Oerlikon Schlafhorst (already prior to that, Oerlikon Schlafhorst supplied 6 machines Autoconer type RM of different generations and since that time the customer is completely satisfied with these machines). Added to these are optimally adapted climate control systems (LTG), cleaning systems (Sohler-Neuenhauser), transport systems and related equipment. The project is currently just at the delivery stage, with the customer preparing its building for the installation and assembly of the spinning lines. Up to handover of the keys and scheduled production start at the beginning of 2011, the project partners will press ahead jointly with the work, which naturally includes the provision of detailed documentation, training and service. Once this project is executed, Kombolcha Textile Share Company (Ethiopia) will increase its productivity enormously and consolidate its market position further. Since it was founded in 1986 the company has established itself at home and abroad as a supplier of a wide variety of CO yarns and woven fabrics. By investing in these ultra-modern technologies and machines, Kombolcha Textile Share Company aims to add steadily to its existing customer base in the long term through improved quality, shorter delivery times and new product offerings.

The overall spinning mill project comprises both the delivery of preparatory machines from Trützschler and the supply of 3 roving
