18 LINK 59 . 1 /2012 PRODUCT NEWS Profitable Ring Spinning has a Name: Rieter G 32 In the textile industry, the name Rieter stands for innovation and dependability, for system supplier and technological competence. This reputation is based on the continual, coordinated development of all system-relevant machines for the customers’ benefit. Fig. 1 G 32 Ring spinning machine – high-quality yarns economically produced. Scientific analyses and physical basis research generally form the initial stage of a new development; new production techniques allow the realization and a very well trained, customer-orientated service ensures the recognized high availability of the entire systems. Rieter utilizes this potential to increase the performance of all system components without relinquishing the economic benefits for the customers. Adaptable solutions for the specific environment of the customers ensure their profitability. A good example is the G 32 ring spinning machine. This machine has been designed as an economic solution where the customer does not have to forego the familiar quality. Unique technical solutions are then integrated when the economic advantage for the customer is obvious. New solutions are sought in cases where existing solutions do not fulfil economic requirements. Three fundamental requirements form the basis running through the entire development process: the renowned Rieter yarn quality, high dependability and lowest energy consumption per produced kg of yarn. In addition, the EliTe compacting system was optionally integrated in order to create a machine basis for conventional and compacted ring yarn. Renowned Rieter Yarn Quality Based on extensive analyses, the spinning geometry was further improved with the change from the previous G 33 model to the present G 35 standard ring spinning machine and the Ri-Q-Draft35 resulted. The entire know-how of this development was also adopted as a feature of the G 32. Advantages over other competitors are the further reduced ends down ratio with increased speed potential. High Level of Dependability In the meantime, Rieter has commissioned more than 2 000 ring spinning machines with 1 200 and more spindles at customers worldwide. Of particular importance here is the uniformity of the yarn quality

Stateof-the-art TITAN rings in combination with HPS-18 and HPS-25 spindles stand for extremely long life cycles and lowest energy consumption. The cops change system with SERVOgrip and ROBOdoff provides greatest dependability. SERVOgrip is the description for the controlled cops change without underwinding in combination with adaptable twist factor for sure separation of the yarn ends with all yarn counts and fiber types. ROBOdoff is the widelyknown, self-controlling and efficient doffer. The combination ensures a very low ratio of start-up ends down of approx. 0.7 % to 1.5 %. Lowest Energy Consumption per kg Yarn Rieter carried out extensive measurements under the same conditions for its own G 32 as well as for competitor machines. It was shown that depending on the spindle speed, energy savings with the G 32 from 5 % to 8 %, and in some cases even higher, could be measured. Generally with the G 32 customers operate with up to 15 % higher spindle speeds compared to competitor machines, due to the improved spinning stability. LINK 59 . 1 /2012 PRODUCT NEWS Combined with the lower start-up and operational ends down, the following macroeconomic advantages could be achieved at customers: • up to 8 % lower energy consumption per kg of yarn [kWh/kg], • up to 25 % more production per spindle per time unit, • up to 30 % lower personnel requirement per kg of yarn. Impressive values that in combination with the renowned durability of Rieter machines ensure the profitability of the investment. Integrable EliTe Compacting System With the construction of the G 32 attention was paid to creating a universal machine that is designed to cover a wide range of applications. This also includes the integration of the Rieter core yarn system and the well-known EliTe compacting system. The latter is currently supplied with central suction and filter box which guarantees lower energy costs compared to small sectional motors as well as a high level of dependability. A further advantage over small sectional motors is here the modularity. The machine can both be prepared for EliTe and also be supplied with the integrated EliTe system. It goes without saying that the machine can also be retrofitted on site. Rieter has achieved a real coup with this machine. Flexibility, yarn quality, durability and low yarn production costs united in one system – the G 32 ring spinning machine has rightly earned its supplementary name: The Money Spinner. 12-108 • Andreas Hellwig Head Product Management Ring Spinning Winterthur andreas.hellwig@rieter.com 19
