3. 夾線彈簧片的壓力調整：
當下勾針線被切斷後，下勾針這端之
線頭須被夾線彈簧片與活動刀片穩定
夾住。調節夾線彈簧之壓力，可由螺
絲(H)旋轉調整。(順時鐘方向壓力愈
強，反時鐘方向壓力變弱)。(圖28)
注意：
夾線彈簧片之壓力調整須適中，壓力太強會
減短活 刀片之壽命，壓力太弱則下勾針線頭
易脫落。壓力之強度以能輕易切斷線即可。
3. When the looper thread has been cut
off, the Clamp Spring and Moving Knife
will clip the thread in stable. To increase
the pressure of clipping thread turn the
screw (H) clockwise and decrease the
pressure turn the screw (H) counter-
clockwise. (Fig. 28)
Remark :
The pressure of Clamp Spring must be moderate﹒
If the pressure has been adjusted into too
strong, it will decrease the life of Moving
Knife﹒ If the pressure has been adjusted
into too weak, the looper thread will easy
to lose from the Clamp Spring﹒ What is moderate
pressure? It is meaning that the pressure
to
cut the thread easily﹒
