One of the more traditional processes in yarn formation it comes in a few different shapes and forms, as Worsted, semi worsted but also the woolen variety. Due to the very different nature of the raw materials used, the various end uses and also the longevity of the machines, a multitude of different sizes, shapes and qualities of spinning components, as in cots, balloon cots, aprons, forming aprons, long cots, rubbing aprons, drafting aprons and cots, are in demand in the market. OTALO with its longstanding tradition and knowledge will be able to advise and provide the fitting set of components for any combination and materials. Our specialists will find and advise the best possible combination for a smooth and economic spinning operation.

Today the most recent and also fastest form of staple fiber yarn formation is the airjet spinning process. Having come to pass over the past 30 years, after having been invented nearly 100 years ago, the stress on the spinning components is very high and the accuracy needed is very demanding on the component supplier. OTALO components will yield the necessary life time and quality required for this very special application. Depending on machines in process OTALO will provide you with a fitting set of OTALO components needed.

Bast fibers in their cottonized form will be used as blending partners for other fibers and processed like with one of the above systems. A different set of spinning components is needed if the so called technical fibers are being processed in the wet spinning process. Special cots and aprons are needed and we are certainly happy to assist you to find the suitable components of the OTALO range for your machines.

In a lot of applications rubber coated or elastic rollers are needed to achieve precise yarn guiding or accurate adjustment of brake force. Due to the vast amount of different yarn materials, yarn counts, processes and ambient conditions, the correct assessment of the suitable material and hardness as well dimensions and execution of the roller is crucial for the success and reliability of the operation. We will assist you in the selection of the most suitable roller depending on your specific operational situation.



TEXTURIZING
ORDER NOW
Short staple spinning

In most circumstances friction texturizing processes require either cots or aprons for the optimal result in yarn quality and evenness of the texturizing effect. Mostly for finer yarn counts apron guiding devices are in use. Aprons are selected based on a few filament properties such as raw materials, yarn counts and desired effects as well as the speed level of the machine. We will certainly advise the best possible combination of durability and quality, based on the demands you will ask for. Similarly there are guiding and tensioning devices that apply cots. The application range of these devices is much higher than the ones typically found for aprons. Therefore there is an even wider range of possible products and speeds that influence the selection of the right choice of cot. We will certainly be happy to assist you with the selection of the optimal product for your processes.

Yarn and tension control in twisting and doubling is one of the more crucial parameters for quality. Especially for very sensitive and technical yarns variation of parameters can lead to quality yield problems in the yarn. We will try to devise and recommend the best possible solution for your individual situation based on our long expertise in that field. Package formation is another critical part of the quality of twisted and doubled yarns. The optimal friction of the yarn with the cylinder cover will be the key to a satisfactory final yarn package. OTALOform family of products will deliver exactly that. We will advise you, which one will be optimal for your process.

The OTALO brand has been in use by the otto kühnen family company from as early on as 1905. The invention of oil resistant synthetical rubber triggered elaborate experimentation and development and in 1932 otto kühnen applied for a patent for a cot of this material, which was granted in 1936. At that time otto kühnen decided to use the OTALO brand for that innovation. Over the years however there has been an ever widening field of application of that technology and therefore there have been numerous additions to the product range. One of the first, high draft aprons, one of the last, products for unconventional spinning systems.

 

OTALO products are constantly tested and scrutinized. Application experts in the field work hand in hand with product development to get the best possible solution and optimum performance out of OTALO products. lf required, individual solutions can be worked out with specific customers. To respond to the ever increasing need for improvements in production productivity and flexibility otto kühnen can also offer consulting services that range from individual process/ machinery problems to whole mill assessments. The entire staff of otto kühnen will assist every customer in the best possible way.
