Optimizing draw frame performance

Draw frames play a key role in every spinning mill in determining the quality of the yarn. To keep the quality of sliver and yarn consistently high and achieve high machine productivity, maintenance of the draw frame is of utmost importance.

Regular maintenance of the draw frame is crucial to achieve high productivity and excellent sliver quality.

Mill managers today face increasing production requirements and a shortage of manpower at the same time. Machines must run constantly at maximum efficiency and availability, while requiring as little maintenance as possible.

Nevertheless, maintenance is still an important part of daily business. Each unexpected equipment failure can:

interrupt the production schedule,

lead to costly downtime,

increase the amount of waste,

reduce the sliver and yarn quality,

reduce the lifetime of components or the machine.

For example, a short length of faulty sliver delivered by the draw frame is enough to result in several meters of inadequate or low-quality yarn. Dirty or dusty guide rollers and guiding tubes can cause inconsistencies in the sliver thickness. Missing lubrication of the drive elements can reduce component lifetime because of drive slippage.

Benefits resulting from regular maintenance

All of that can be prevented by regular maintenance. To support customers in their daily challenges, Rieter provides a comprehensive portfolio of spare parts and services including parts packages to improve the performance at all stages of the machine lifetime. Furthermore, maintenance booklets are available summarizing and illustrating necessary maintenance procedures. They include recommendations for cleaning and lubrication of critical areas of the draw frame and provide tables with suggested parts exchange intervals.

While the maintenance booklet helps perform regular maintenance, ordering and stocking parts is made easy by ESSENTIALorder. This online platform includes a customer specific spare parts catalog and assists spinning mills in on-time ordering of parts as well as optimizing the amount of stock. The system is available 24 hours a day, enabling customers to submit orders from anywhere at any time.

As a result, downtimes can be prevented and the draw frames keep running at maximum efficiency. It will be possible to achieve higher productivity, excellent sliver quality and increase the lifetime of the machines. Rieter service specialists support customers in maintaining their draw frames to reach their targets.

Rieter advances strategic repositioning amid market volatility

Rieter successfully completed the acquisition of Barmag on February 2, 2026, and reached an important milestone in the company’s repositioning. Barmag will be integrated into the Rieter Group as the “Man-Made Fiber” Division. With this strategically transformative acquisition, Rieter is expanding its core business beyond the short-staple fiber business in a targeted way. This positions Rieter as the global market leader along the entire value chain for natural and man-made fibers. In addition, as a complete systems supplier, Rieter is further strengthening its technological leadership in the areas of automation and digitization.

Rieter responds to higher raw material prices

Global political and economic developments have been leading to rising raw material and energy costs for some time. The textile machinery industry is also affected by this trend. Rieter machines and components consist to a large extent of steel, copper, aluminum and electronics. These materials in particular have seen higher demand and higher prices in recent months.

Rieter adjusts group structure in preparation for Barmag integration

The planned acquisition of the “Barmag” Division of OC Oerlikon will create the leading system provider worldwide for natural and man-made fibers. Rieter is confident it will receive all regulatory approvals to complete the acquisition in the fourth quarter of 2025. The Rieter Group is therefore adjusting its Group structure as of January 1, 2026, to take this acquisition into account and to be able to provide an even more agile response to market challenges.

Barmag presents the next generation of POY production – energy-efficient and partial-automated

With POY 2.0, Barmag is introducing a completely redesigned spinning concept that takes the production of partially oriented yarn (POY) to a new level in terms of technology and economy. The solution, which was presented to a selected audience of experts for the first time at ITMA Asia + CITME 2025, was met with great enthusiasm: several yarn producers worldwide immediately expressed their interest in a pilot plant.

Development of bio-based polyethylene fibers for textile applications – BB Engineering partici-pates in the bioPEtex research project

In the German research project bioPEtex, BB Engineering (BBE) is working with other partners to develop textiles made from 100% bio-based polyethylene (PE). The aim is to make use of this poly-mer, which has hardly been used in the chemical fiber industry to date. BBE is contributing its spinning and texturizing expertise and developing the texturing process on an industrial scale. The first promising results are already available – opening up new opportu-nities for sustainable and economically attractive applications in the textile industry.

High-performance yarns for tomorrow's mobility

At this year's Techtextil in Frankfurt (April 21–24), Barmag will be presenting comprehensive solutions for the production of industrial filament yarns at the VDMA joint stand (Hall 12, C56). The focus will be on applications that ensure greater safety, durability, and efficiency in automotive engineering.
