Using the threading mechanism that is incorporated within the unit, the yarn is threaded into the heart of the open texturing unit without excessive tension. Yarn tension peaks are significantly lower when closing the unit compared to a fix center unit.
For microfilament yarns in particular, this gentle method of threading results in significantly lower yarn breaks at positional start-up and consequently in a marked reduction in time to thread the entire machine. Moreover, during the process, there is no threading gate, which restricts handling or vision of the yarn path in the open/close unit.
When inserting the threads with an open/close unit significantly lower yarn tension peaks occur compared to a fixcenter unit, which significantly reduces the yarn breaks during threading.
