Draw frames play a key role in every spinning mill in determining the quality of the yarn. To keep the quality of yarn and sliver consistently high and achieve high machine productivity, maintenance of the draw frame is of utmost importance.
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 (Fig. 1) 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
