Ring Spinning Machine G 38

High-quality yarns produced with high flexibility and speed
  1. Flexible production of standard and special yarns
  2. Optimum machine efficiency
  3. Energy-saving

Product Details

The ring spinning machine G 38 with fully electronic drafting system offers extraordinary flexibility. With highest spindle speeds up to 28 000 rpm the production is increased by 12%. Standard and special yarns as well as compact yarns can easily be produced. The G 38 consumes minimal energy thanks to energy-efficient components such as LENA 28 spindles, IE4 main motors and optimized suction systems. In combination with the established and fully automated piecing robot ROBOspin, the G 38 delivers consistent performance with minimal personnel deployment.


With spindle speeds of up to 28 000 rpm, production is increased by 12%. With the High-Speed package (34 mm spinning ring, 16 mm DUI tube/spindle dimension, LENA 28 spindle) the production limits have been considerably extended.

The piecing robot ROBOspin ensures consistent quality of the yarn piecing and high productivity of the ring spinning machine. ROBOspin significantly reduces personnel requirements and facilitates personnel planning.

The G 38 consumes minimal energy thanks to energy-efficient components such as LENA 28 spindles, IE4 main motors and optimized suction systems.


The integrated individual spindle monitoring system ISM premium monitors the running properties of each spinning position and saves personnel costs. The Multilink / Multilot link systems to the Rieter winding machine offer a high degree of intelligent automation with unique flexibility and efficiency.

The quality package Q-Package for cotton decisively improves the fiber guidance between the cradle and the nipping point of the delivery roller.

The proven unique SERVOgrip system makes yarn underwinding for doffing preparation redundant. This reduces fiber fly and ensures high yarn quality.


The MMF Q-package simplifies the processing of man-made fibers and blends,  therefore improving the performance of the machine. Rieter offers a complete ring spinning system that is designed to process recycled fibers in the best possible way.

The compacting devices COMPACTdrum, COMPACTapron and COMPACTeasy can simply be plugged in and out. For all machine lengths, the G 38 can be equipped with devices for slub (VARIOspin), core, and twin yarn production.

Yarn count, twist, and twist direction are easy to adjust on the operating unit. The fully electronic drafting system FLEXIdraft maximizes the production time and allows extraordinary flexibility.

  • High-Speed Package for Ring and Compact-Spinning

    Maximizing the productivity in ring and compact-spinning is an enormous challenge for the spinning mills. The Rieter specialists have put together a High-Speed Package, in which the components are optimally matched to one another: LENA 28 spindle + smaller spinning ring with a 34 mm diameter + spinning tubes with smaller DUI of 16 mm. This unique combination is the key for high-speed spinning.

  • Piecing robot ROBOspin

    The piecing robot ROBOspin repairs ends down in Rieter ring and compact-spinning machines. Automating this process ensures a high productivity, reduces labor costs and makes the operational organization of the spinning mill easier.



  • Ring-Winder-Connect in ESSENTIALoptimize

    The Rieter ring and compact-spinning machines form an intelligent subsystem with the winding machine Autoconer X6. Proven monitoring systems are already integrated: ISM premium in the ring spinning machine, SPID online quality monitoring in the winding machine. The new Ring-Winder-Connect module compares and analyzes data from both machines. The integration into ESSENTIALoptimize creates a new level of process optimization.


Com4 yarns

Yarns for the most exacting requirements that ensure competitiveness in a dynamic market are Com4 yarns. Spun on Rieter ring, compact, rotor or air-jet spinning machines the Com4 yarns are characterized by excellent quality. Rieter customers profit from optimized production costs and good selling outlets.
