The Secret to Achieving Best Sliver Quality - Draw Frame Maintenance and SERVOdrive Upgrade

Rieter’s new draw frame maintenance concept takes a comprehensive approach. It defines the machine as a system of components that need to work together as a team so they can deliver the best results. One of the key components is the levelling system. Replacing it with a new SERVOdrive not only improves the quality of the sliver. It also reduces overall maintenance costs as high-maintenance components such as the gearbox are eliminated.

Recognizing Signs of Fatigue

Draw frames improve the evenness of the sliver for the downstream spinning process. After years of operation and heavy use, the quality of the sliver shows minute variations. As parts slightly wear out over time, the machines can no longer run at high speeds which is why some operators choose to reduce the machine speed to achieve the same quality. In practice the quality monitor or control settings are often enlarged or bypassed to increase speed, resulting in lower quality. In these cases, maintenance restores the machine performance and reduces the number of warnings and standstills.
