本機采用新型旋轉挑線桿，即便是在極低的張力下也能得高品質且穩定的縫跡。采用了梭軸配合補償機構，旋梭在勾線時的左右位置均等，可防止跳針以及斷線。對于有伸縮性的面料，裝備了微量的抬壓腳裝置就會使壓腳輕輕浮起，然后進行縫制，縫出的線跡整潔美觀，特別設計的繞線器。使用更快捷方便。
The machine is equipped with a hook-driving shaft-offset mechanism which places the hook-rotating shaft off-center of zigzag stroke of the needle.This mechanism allows the blade point of the hook to catch the needle thread every time regardless of the needle throwing direction.As a result,this machine is immune to sewing trouble,such as stitch skipping and thread breakage.Annoyances likely to occur with the conventional machine.Especially when the needle throws to the right.
