Ring Spinning Machine G 38

Highest productivity in ring spinning with lowest energy consumption
  1. Highest spinning speeds
  2. High Machine Efficiency
  3. Flexible production of standard, compact and special yarns

Product Details

With spindle speeds up to 28 000 rpm the production is on the highest level. The machine consumes minimal energy thanks to energy-efficient components such as LENA 28 spindles, IE4 main motors and optimized suction systems. Customers benefit from the 25% faster doffing system. The new and faster cop transport system SERVOdisc needs less maintenance. The compacting devices COMPACTdrum and COMPACTapron for high-quality compact yarns as well as systems for the spinning of slub, twin, and core yarns make the machine very flexible. The piecing robot ROBOspin and the Multilink/Multilot systems for Rieter winding machines offer a high level of automation with unique flexibility. The individual spindle monitoring system ISM premium is now standard. The new version of the ring spinning machine G 38 is available either as fully or semi-electronic system on demand.


25% faster doffing with a cycle time of only 90 seconds brings massive productivity benefits. The 12% faster cop transport SERVOdisc for systems linked to the winding machine needs less maintenance.

The High-Speed Package (34 mm spinning ring, 16 mm DUI tube/spindle dimension, LENA 28 spindle) enables maximum productivity. The G 38 runs with spindle speeds of up to 28 000 rpm and high delivery speeds of up to 40 m/min.

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


The individual spindle monitoring system ISM premium is now standard for all Rieter ring and compact-spinning machines. It monitors the running properties and simplifies operator guiding. Roving stop and the intelligent link system to the winder guarantee high yarn quality and maximum raw material utilization.

Special tools simplify 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 quality package Q-Package for cotton decisively improves the fiber guidance between the cradle and the nipping point of the delivery roller. The new short balloon setting reduces yarn tension peaks and lowers the yarn breaks rates. Alternatively, the production speed can be increased.


The new G 38 machine is available as fully electronic or semi-electronic system. The main difference lies in the drafting drive. All important yarn parameters can be easily set on the panel. On the fully electronic machine, also the yarn count can be changed on the panel.

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, core, and twin yarn production.

The piecing robot ROBOspin ensures consistent quality of the yarn piecing and significantly reduces personnel requirements. The G 38 can work as a stand-alone machine or as a direct link or Multilink with the Rieter winding machine Autoconer X6.

  • 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.
