The new groove and sensing roll unit DISC LEVELLER sets a benchmark in quality: A draw frame sliver CV1m of 0.4 % or less, and a yarn count variation clearly below 1% are the realistic objectives set by modern spinning mills.
The total draft is specified in the spinning plan. The break draft is material-related and quality-relevant. An incorrect setting, for instance, can result in an unnecessarily large number of imperfections and reduced yarn strength, as well as lower efficiency at the spinning machine.
The optionally available self-optimising function AUTO DRAFT ensures that the Trützschler autoleveller Draw Frame TD 8 is always perfectly set for the break draft. The ideal main drafting point is automatically determined by the standard self-optimising function OPTI-SET.
