摘要

The yarn twister, which takes at least one yarn (5) from a supply bobbin (15), has a yarn guide (10) to take off the yarn. The yarn guide slides on a guide rail (13) along an axis (A) parallel to the bobbin axis (C), and at a gap from it. The position of the yarn guide to take off the yarn is set at a height level (H) of the bobbin, according to the wound yarn parameters.
