Economic Machine Concept Cost-efficient production Mechanical drafting system drive reduces investment costs For constant production with infrequent changes in the yarn count, the mechanical drafting system drive is a good solution. Beside the energy and personnel costs, the investment costs are an important cost factor for the production of ring spinning yarns. A machine with mechanical drives is the ideal solution to keep these costs low. No ends-down with a power failure In the event of a power failure, the rotation energy of the spindles is used to supply the machine controls with electricity. To achieve this, the main motor switches to generator mode. With a power failure up to 2 seconds, the machine automatically accelerates to again reach the operating speed. With longer interruptions, the machine is decelerated in a controlled manner, thereby avoiding additional ends down. Controls with power failure reduction of production loss Spindle speed [rpm] Electricity Power failure Power failure < 2 seconds Ramp-up to full speed Power failure > 2 seconds controlled machine stop Spindle motor: Generator function Spindle motor: Motor function Intermediate drive makes long machines possible Numerous advantages speak for the use of long machines. Not only the total number of ring spinning or winding machines is consequently reduced but also the costs for maintenance and air-conditioning. Long machines use an additional drive unit for the middle bottom roller, positioned in the middle of the machine. The torsion forces on the bottom roller decrease and the uniform running of the bottom roller guarantees consistent quality along the whole length of the machine. After doffing, the drafting unit performs a uniform start-up on all spinning positions; delays caused by torsion and thus start-up breakages are prevented. 10
Machine concept and quality components for highest productivity Alongside the power consumption, highest possible productivity is crucial for favourable production costs. The spinning speed is especially reliant on the spinning machine, alongside raw material and process management in the preparation. Based on the unique Rieter spinning geometry as well as on the consistent use of quality components and precise manufacture, the G 32 ring spinning machine produces at highest spindle speeds. This is also the basis for consistently high yarn quality at maximal production. Easy setting in Z or S direction of twist With the semi-electronic drafting system drive, the number of twists in the yarn and the direction of twist (Z or S) can be very easily changed on the display panel without mechanical modifications. A machine with semi-electronic drives is the ideal solution to keep costs low. Quick and sectional machine installation The sectional delivery and assembly of the machine brings distinct advantages. By means of the prefabricated sections, the assembly time is considerably reduced which positively affects the payback period of the ring spinning plant. The exact pre-assembly in the Rieter works also increases the precision and uniformity of the entire ring spinning facility. Only in this way can a quality yarn be successfully produced at highest speeds for many years. 11
Efficient Doffing High productivity through fast and reliable doffing Doffing without unterwinding With the SERVOgrip, no yarn residues occur that need to be removed from the wharve. As well as saving yarn, it helps to keep the machine clean. Ends down caused by flying yarn remnants are avoided. Rieter is the only manufacturer to offer an exactly controlled clamping crown. The controlled opening and closing of the clamping crown by the ring rail fixes the yarn exactly and ensures a low number of ends down after doffing. In addition, the risk that fibre fly enters the spinning process and leads to yarn faults is prevented. 1 2 3 4 5 6 Working principle SERVOgrip control by means of the ring rail Improved yarn cutting for man-made fibres With the patented reduction of the yarn twist during the back winding and the optional SERVOgrip knife on the clamping crown, also high-strength yarns or core yarn specialities can be cutted reliably. Self-monitoring gripper The system monitors itself by means of the special profile of the doffer beam and the releasable gripper. In the event of failures, the doffing process is stopped by the pressure monitor. This ensures that all full cops are taken off and an empty tube is put onto each spindle. 12
Reliable cops transport through SERVOdisc The SERVOdisc system works with peg trays that are clipped into a conveyor belt. This achieves a high level of precision in positioning. During doffing, the full cops and the empty tubes can thus be precisely taken over and removed. High dependability and short doffing times guarantee high machine efficiency over a long period. The SERVOdisc system is an open system and is thus practically selfcleaning under all circumstances. It is driven by two diagonally offset 70 watt motors and operates with 10 % of the energy consumption of pneumatic solutions. Flexible automation With the SERVOdisc system, the end spinning machine can be directly linked with a winder or with the ROBOload. According to the customer's requirements, various automation solutions can thereby be realised. The interface for ROBOload and link are identical. Thereby a ROBOload machine can also be docked onto a winder at a later stage. The end spinning machine directly linked with the winder Rieter ROBOload the solution for stand-alone machines 13
Save Energy with Suction Tube ECOrized The suction tube ECOrized reduces the energy consumption by 10 % Substantial energy saving The suction tube ECOrized is a further outstanding development from Rieter. The lower air volume at the spinning position leads to a reduction of the required suction power by up to 50 % which results in clear cost savings. This gives an average energy saving of approx 10 % across the entire yarn count range. With ECOrized, significantly reduce energy consumption 100 95 Energy consumption [%] 90 85 80 30 60 80 100 Yarn count [Ne] Standard suction tube Suction tube ECOrized Airflow rate as required - 10 W - There is a device on every spinning position for the removal by suction of ends down and hard ends the suction tube. The opening of the suction tube is large enough to also handle hard ends. Under normal spinning conditions, this cross-section and the corresponding air volume that is constantly sucked in is far too big. The innovative suction tube ECOrized has a plastic flap that allows a significant energy and cost saving. The light plastic flap floats in the airflow of the suction system, without touching the yarn. To extract an ends down, the smaller suction opening and the substantially reduced airflow are fully adequate. With hard ends, there will be so much fibre delivered by the drafting system that the closed flap is pushed open. The resulting large tube diameter reliably withdraws hard ends, irrespective of the traversing point at which the yarn is found. Standard airflow Airflow with hard ends - 7 W - - 3.5 W - - 0 W - - 10 W - - 7 W - - 3.5 W - - 50 % - 0 W - 14
Energy-saving Drive Rieter 4-spindle tape drive uses minimal energy The Rieter 4-spindle tape drive is energy saving and easy to handle. With the 90 enlacement on the spindle, a good drive of the spindle can be secured with a low contact pressure. This contact pressure ensures minimal force on the spindle bearings and thus secures the lowest possible energy consumption. The large speed range with optimal efficiency secures the necessary flexibility, as a wide yarn count range can be operated with low power consumption. With major changes in the speed, the optimal speed range can be adjusted by means of a central exchange of the drive pulley. With the Rieter 4-spindle tape drive, changing between Z and S yarn twist direction is possible without mechanical switchover of the tape tensioning apparatus. The large main motor offers the best efficiency and therefore the lowest energy consumption of all drive systems. Optimal power transmission due to 90 contact area reduces the energy consumption 15
Superior Yarn Quality due to Precise Drafting System Ri-Q-Draft various options for quality yarns Ri-Q-Draft with Ri-Q-Bridge the solid basis The Ri-Q-Draft system guarantees for most applications an optimal fibre guidance with very stable running behaviour. The Ri-Q-Bridge, a key component in the spinning process, and the optimised position and form of the cradle shorten the distance to the clamping point of the delivery roller pair and thereby achieve best yarn quality. The optimal positioning of all technology parts and good running of the bottom aprons ensure ideal fibre guidance in the main drafting zone. Pressure relief of the drafting system cylinder ensure highest yarn evenness The pneumatic pressure relief of the drafting system cylinder ensures that the top rollers do not develop pressure points during longer downtimes, which prevents periodical faults in the yarn. With the G 32 ring spinning machine, maximum yarn quality with best prerequisites for the textile end product is uncompromisingly produced.

Q-Package* the quality package for cotton and man-made fibres The quality package for cotton and man-made fibres with the step nose bar bridge and the new cradle combined with the most technologically advanced pins noticeably improve the yarn quality. Fibre guidance between the cradle and the nipping point of the delivery roller pair has been further improved. Consequently, the yarn evenness (CVm) has been improved by one percent absolute. At the same time, yarn imperfections have been reduced by 10 30 %. * Option Man-made fibre package* increases the efficiency of the spinning process With the man-made fibre package, an improvement of the entire spinning performance for man-made fibres and blends has been achieved. The SERVOgrip knife reliably cuts the yarn at doffing and prevents start-up breakages. Bottom rollers with a greater diameter can be optionally used. This improves the running performance, especially with long man-made fibres. Due to the metal reinforcement of the front edges of the separators, their life cycle is significantly increased. * Option 17
Easy Machine Setting Quickly in production Easy entering of the spinning data Important machine functions are centrally entered. The various menus of the machine control simplify the entry process. The operator is guided step by step through the menu. As important lot data such as yarn count, twist and speed curve are centrally set, the time required for a lot change is reduced. Productivity is more than maximum spindle speed Up to 2 % higher productivity at the same maximal spindle speed Spindle speed 100 % 90 % 80 % 70 % Rieter Others Particularly in the cops build-up stage, there is hidden potential. Through the precise machine construction and the use of high-quality components, interesting production increases can be specifically achieved in this critical area. Thus, with a yarn count of Ne 30 for example, 6 500 kilograms more yarn can be produced per year and machine. 60 % 0 40 80 120 160 Cops build-up [mm] Reliable machine setting If in large plants many machines are operating with the same yarn count, it is important that the quality on all machines is the same. Uniform setting of all machines offers the greatest security for consistent quality within the plant. By means of the USB interface, the data is quickly and easily transferred to other machines. If the optimal spinning curve for a yarn on one machine is determined, then other machines can be easily adjusted. This facilitates optimisation of the spinning mill. 18
Special Yarns for Innovations in the World of Fashion Integrable systems* for the economical production of fashionable yarns A variety of effects with VARIOspin With the optional fancy yarn device VARIOspin, high-quality special yarns can be flexibly produced and fashion trends speedily implemented. This is effected by a servo-gearbox which is superimposed on the proven Rieter gearbox. The sophisticated differential gearbox prevents thin places and significantly improves the running performance in downstream processing. All functions are synchronised and enable a cost-efficient production of fancy yarns with the accustomed Rieter quality. Effect length Basic yarn count Effect on effect max. mass: 500 % min. length: 1/3 fibre length 100 % min. length: 1/3 fibre length max. mass: 500 % min. length: 1/3 fibre length min. ramp length: 1/3 fibre length min. ramp length: 1/3 fibre length min. ramp length: 1/3 fibre length Effects differ in the variation of the effect mass (thickness) and effect length. With VARIOspin also long thin places, which are finer then the basic yarn count, can be intentionally produced. This applies especially to knitwear. Special effects such as overlapping effects (effect on effect) round off the possibilities. A variety of effect designs can be easily programmed and reliably produced. Core yarns three products to choose from The sophisticated equipment with traversing core guidance rollers and no contact with the rubber rollers allow efficient and faultless production. Three different core yarns can be economically produced. With soft core yarn with elastane and hard core yarn, often with polyester, a single filament is used as the core. In the denim segment, a duo-core yarn is increasingly used. This consists of feeding an elastane and a bi-component polyester simultaneously. Thus, super-stretch yarns with high elasticity can be manufactured. Further quality yarns Further possibilities are twin yarns and compacted yarns (EliTe). With the flexible and costeffective production of diverse special yarns, it is possible to easily and quickly react to changing market requirements. * Option 19
High Reliability Long service life due to high-grade components Quality spindles and tubes for optimal running behaviour All machines are delivered exclusively with proven Novibra quality spindles. These are not only convincing by their improved running properties and fewer ends down, but also by a far lower energy consumption and noise level compared to other products. The vibration-free running of the spindle is the basis for high spindle speeds. Only smooth running of the spindle prevents tension peaks in the yarn which could lead to ends down. Novibra spindles in combination with Rieter quality tubes guarantee the best spinning results. The quality spinning tube, Ri-Q-Tube*, convinces by its special synthetic composition and the associated dimensional stability. It offers a highly accurate concentricity and so allows highest spindle speeds. The minimal load exerted on the spindle bearings ensures a long service life, even at high speeds. Quality rings for a long service life The high-quality TITAN spinning rings from Bräcker are included in the standard package for the G 32 ring spinning machine. By the deliberate use of high-quality key components, an optimal spinning process with a resulting perfect yarn is attained. RI-Q-Cot* for highest yarn quality The top roller cots developed by Rieter guarantee faultless yarn production with high quality. According to requirements, various Ri-Q-Cot top rollers are available. The specification of these cots is based on many years of experience and intensive application in practical spinning. * Option 20
Production and Quality Monitoring High efficiency through specific deployment of human resources Effective ends down detection The individual spindle monitoring ISM* with the 3-stage display concept guides the machine operator directly to the spindles with ends down by means of signal lamps. Unnecessary monitoring checks are eliminated. The spinner can work more efficiently and thus operate more spindles. This is achieved by different levels of the display. The first stage are signal lamps on the machine head end and machine foot end. They light up as soon as the defined limit for ends down is exceeded. Through LEDs in each section, the operator can recognise in which section along the machine ends down must be pieced. Every spindle additionally has an LED, so that the operator can directly identify the affected spindle. Without individual spindle monitoring long distances for the operator * Option Optimised path with individual spindle monitoring saves time and improves the efficiency Constant yarn twist through speed monitoring The permanent speed monitoring of the individual spindles with the individual spindle monitoring ISM ensures the yarn quality. If a spindle runs outside the defined specifications, this is indicated by the LED blinking. The LED display at the section and on the individual spindles leads the operator directly to the affected spindle 21
