质量
集成单锭监测系统ISM premium现为各种立达环锭细纱机和紧密纺纱机的标配功能。它可以监测运行性能和简化挡车工的引导。粗纱自停和智能细络联系统可确保出色的纱线品质，最大限度地提高原料利用率。
专用工具可简化化纤及其混纺的加工过程，从而提升机器性能。立达拥有旨在以卓越方式加工再生纤维的全流程环锭纺系统。
用于棉纺的高品质套件Q-Package可改善上销与输出罗拉钳口之间的纤维引导。新的短气圈环可降低纱线张力峰值和断头率。或者，可提高生产速度。
灵活性
新型G 38机器可采用全电子系统或半电子系统。主要区别在于牵伸驱动装置。可在面板上轻松设置所有重要的纱线参数。在全电子机器上，还可以在面板上改变纱线支数。
紧密纺装置COMPACTdrum、COMPACTapron和COMPACTeasy拆装简便。无论G 38机身长度是多少，都可以配备竹节纱、包芯纱和双股纱的生产装置。
接头机械手ROBOspin可确保稳定的纱线接头质量，并显著降低人工需求。G 38可作为独立机器使用，或采用与立达络筒机Autoconer X6直连或多联的形式使用。

Frequently asked questions
What is new in the latest G 38 compared to previous models?
Latest G 38 has the following new features:
- a new cop transport SERVOdisc
- the short-balloon setting
- the High-Speed package (optional)
- a faster doffer (optional)
- a new HMI
- air-cooled drafting motors
How can I achieve higher speeds on my ring spinning machine G 38?
The further development of the Rieter ring and compact-spinning machines with the High-Speed Package yields enormous benefits to the customer in terms of productivity, flexibility, and energy savings. The High-Speed Package consists of three components that enable maximum spindle speeds.
- The high-precision spindle LENA 28
- A smaller ring with a diameter of just 34 mm which reduces traveler speed and opens up potential for an increase in spindle rotation
- A tube with a smaller bottom inner diameter (DUI) to get the the same yarn weight on the tube and to ensure the number of doffing processes remains the same.
With a delivery speed of up to 40 m/min, the G 38 with the High-Speed Package produces 12% more yarn.
Is the short-balloon setting a standard feature?
The short-balloon setting is standard for new machines and can also be ordered as an upgrade for already installed machines.
What performance improvement does the short-balloon setting offer?
Trials at spinning mills showed that this brings advantages in terms of up to 10% less ends down rates in average and longer traveler lifetime. Alternatively, the ends down rate can be kept constant, and instead the spindle speed can be increased by 3 to 6%. With an 8% longer traveler lifetime spinning mills save maintenance costs and reduce downtimes.
Can I also produce slub, core and twin yarn with the G 38?
Yes, the optional VARIOspin drive system for slub yarn production is completely integrated into the fully electronic version, with a separate panel for easy operation and design.
With the core yarn devices, soft, hard, and dual core yarns can be produced. The devices work with a traversing guide roll for the filament. The traversing system for the filament is aligned with the traversing system of the roving.
To produce a twin yarn, two rovings must run to one spinning position. In the drafting system, both are drafted separately. The rovings are then twisted together in the spinning triangle.
Can the G 38 process man-made fibers?
Rieter offers a full package of components especially for man-made fibers like SERVOgrip knife, bottom rollers with a larger diameter, and reinforced separators. It is a modular set. The individual elements can be configured based on customer requirements. The man-made fiber package improves spinning performance for yarns made of man-made fibers and blends.
The bottom rollers have a larger diameter and improve the running characteristics of the machine when long man-made fibers are used.
What are the benefits of the piecing robot for G 38?
ROBOspin is the piecing robot for Rieter ring and compact-spinning machines. One robot per machine side repairs ends down that occur while the machine is running or during doffing. The robot receives information about the position of the ends down from the integrated individual spindle monitoring (ISM).
