  1. Highest spindle speed and full flexibility
  2. Reliable production of high-quality yarns
  3. Successful concept to save energy

Product details

The compact-spinning machine K 48 produces compact yarns with highest performance and fewer wear parts. The fully electronic drafting system FLEXIdraft provides extraordinary flexibility to the machine. With highest spindle speeds up to 28 000 rpm the production is increased by 12%. In combination with the established piecing robot ROBOspin, the K 48 delivers consistent performance with minimal personnel deployment.


The K 48 consumes minimal energy thanks to energy-efficient components such as LENA 28 spindles, IE4 main motors and optimized suction systems for compacting.

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.

There are fewer wear parts for the machine as the system does not include a compacting apron and is equipped with technology components that have long service lives.


The integrated individual spindle monitoring system ISM premium monitors the running properties of each spinning position. The piecing robot ROBOspin ensures consistent quality of the yarn piecing. ROBOspin significantly reduces dependency on work force.

The air guide element Detect ensures precise air guiding and monitors the compacting process at each spinning position. This ensures a consistently high yarn quality.

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


A highly abrasion-resistant sieve drum coating increases the application range of the K 48. Different raw materials, blends, and yarn counts can be spun with the shortest time for a machine changeover.

For all machine lengths, the K 48 can be equipped with devices for slub (VARIOspin), core, and twin yarn production.

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

  • 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.
