High-quality yarns produced with high efficiency
  1. High level of machine efficiency
  2. Energy-saving
  3. Optimized personnel deployment

Product Details

The ring spinning machine G 37 with the semi-electronic drafting meets all requirements for an economical yarn production. Customers profit from a top-quality machine, efficient energy utilization with LENA spindles, IE4 main motors and optimized suction systems. The new generation of compacting devices for high-quality compact yarn and systems for slub, twin, and core yarns make the G 37 very flexible.

The integrated individual spindle monitoring system ISM basic reduces personnel costs by about 3%. With the fully automated piecing robot ROBOspin, the G 37 reaches a top-level efficiency with enormous personnel savings.


The G 37 with its semi-electronic drafting system allows a flexible and fast change of yarn parameters. This leads to a short time for a machine changeover. 

The machine uses minimal energy thanks to energy-efficient components such as LENA spindles, IE4 main motors and optimized suction systems including the innovative suction tube ECOrized.

The integrated individual spindle monitoring system ISM basic ensures a high machine efficiency and can save about 3% of personnel costs.


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

The piecing robot ROBOspin ensures consistent quality of the yarn piecing and a highly productive spinning machine. ROBOspin significantly reduces personnel requirements and makes the human resource planning easier.


It is easy to carry out a changeover from ring to compact yarn. The compacting devices COMPACTdrum and COMPACTeasy can be simply plugged on and off. Furthermore, the machine can be equipped with the compact-spinning system EliTe. 

To meet the rapidly changing market needs, the G 37 can be equipped with systems for the production of slub, core, and twin yarn.

  • G 37 with 1 200 Spindles

    The new configuration of the G 37 with 1 200 spindles offers an attractive price-performance ratio. It can be integrated into an existing system to save space or can replace older machines. The specially designed Novibra spindle HPS 22 reaches speeds of up to 22 000 rpm. Bräcker spinning rings and Rieter aprons ensure consistent yarn quality and a reduction in machine downtimes. The individual spindle monitoring ISM basic is installed as standard in this shorter configuration.

  • Compacting device COMPACTdrum

    The compacting device COMPACTdrum for the Rieter ring spinning machine is easy to install and remove. It adds a new dimension to reducing hairiness, which impresses customers along with the very low production costs. The device processes all raw materials and covers all yarn counts.

  • Compacting device COMPACTeasy

    The compacting device COMPACTeasy is the new mechanical compacting solution that is attracting customers thanks to its low investment costs. COMPACTeasy produces yarns with excellent characteristics from all standard raw materials. This is based on the intensive double compacting that does not require any additional energy.

  • ESSENTIAL – Rieter Digital Spinning Suite

    ESSENTIAL provides fact based optimization proposals, key performance indicators and even predicts downtime risks. This powerful tool supports management activities with comprehensive and clearly arranged digital analytics. With ESSENTIAL, it is possible to unlock the full range of digital value creation possibilities for the spinning mill.
