Rieter: Optimising 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 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.

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.
