ZS 100 Series Suspended-Spindle Flyers: These units effectively reduce roving hairiness and yarn defects. After passing through the hollow arm of the flyer, the roving immediately engages with the presser arm; guided by the presser's guide eyelet, it is then wound onto the bobbin. Unlike traditional flyers, this design eliminates the "free section" of yarn that is typically subjected to the impact of high-velocity airflow.
