Boosting Performance

After several years of operation, machines do not meet today's requirements anymore and require a little boost to recover their initial productivity. Rieter provides a wide range of solutions to bring your equipment up to its best levels and even beyond. 

Piecing robot ROBOspin

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). 

Customer values

  • Significantly reduced personnel requirements
  • Consistently high machine performance
  • Rapid repair of ends down

Compacting Devices

Rieter offers innovative compacting solutions according to customer needs. With an easy installation and removal, Rieter compacting devices allow to switch between ring and compact yarn within seconds, offering the right solution to obtain a perfect integration of the edge fibers into the yarn.

Three different compacting devices:

-COMPACTdrum, for Rieter ring spinning machines, adds a new dimension in hairiness reduction from yarn to fabric.

-COMPACTeasy, the mechanical compacting solution, requires low investment and zero energy thanks to its y-channel resulting in an intensive double compacting.

-COMPACTapron, the new generation lattice apron compacting technology, offers the best yarn tenacity values thanks to its 3D technology, ensuring 90 - 100% control of the fibers.


PSM drafting motor

The PSM Drafting Motor Upgrade is an economical alternative to the standard drafting motors of the G/K machines. The technology of the Permanent Magnet Synchronous Motor allows a higher output power of the motor by less energy consumption. Further, due to a lower operating temperature, the lifetime of the motor can be increased.

Customer values

  • 29% improved efficiency and 25% higher output power compared to the original motor
  • Reduced energy consumption up to 3% regarding total machine consumption
  • Increased lifetime due to lower motor temperature


The Q-Package combines a newly developed nose bar with the active cradle (instead of the Ri-Q-Bridge and the standard cradle) to allow best yarn quality at lowest manufacturing costs.

Customer values

  • Up to 30% reduced IPI or up to 2% raw-material savings or up to 10% increased production speed
  • High flexibility with individual adjustments to match each specific need of the raw material


The WILDload is an add-on device to the ROBOload. It allows the automatic filling of the ROBOload and eliminates the manual placement of the tubes in the magazine. The capacity of the WILDload tube storage is big enough to fit the needs of even the longest machines.

Customer values

  • Easy and fast reload of the ROBOload
  • Reduced labor costs due to the automatic filling of the ROBOload and tube storage capacity
  • Improved ergonomics by eliminating bent postures

ECOrized suction tubes

With the suction tube ECOrized, an upgrade kit for ring and compact-spinning machines from Rieter, considerable energy savings are achieved.

Suction tubes for G machines

  • Up to 67% reduction in power consumption at the spinning position
  • Low capital costs
  • Short payback within 12 to 18 months

Suction tubes for K machines

  • Saving energy with optimized suction tubes and inverter control by more than 10%
  • Low investment cost

  • Newly designed notch pattern suction head for improved fiber entrainment

Suction insert bright

The suction insert Bright increases the flexibility of compact spinning machines. They allow a precise and constant air flow so fibers are optimally integrated in the fiber package. This improved air flow prevents deposits of dust and fiber particles and results in a fully compacted yarn at all times.

Customer values

  • Precise air guidance and optimized air flow
  • Constant yarn quality
  • Reduced soiling of the suction slots
  • Up to 75% less contamination by fiber fly
  • Less maintenance 
  • Easy identification of chocking per position

Frequency converters

Several frequency converter series have become obsolete due to the evolution of electronics over the past ten years. Upgrading these existing series to the latest generation not only reduces downtime but also extends the lifetime of Rieter machines, ensuring operational safety on ring, compact and rotor spinning machines.

Customer benefits

  • Extended machine lifetime
  • Operation safety
  • Reduced downtime
