4. 梭殼的穿線方法
梭芯轉動方向和穿線方法
(1) 請按照箭頭所指示的方向把梭芯插進去。
(2) 請把機線穿過穿線口①，然後再從張力彈
簧② 的下面躦過去，再次穿過穿線口③，
從④把線拉出來。
(3) 請注意進行直鎖眼縫和鋸齒邊縫時，④的
穿線方法不同。

5. 底線張力的調整
在梭殼穿線口① 在上方的位置，把底線向
上拉出之後，請按照下列的方法調整底線張
力。
• 把線張力螺絲② 向右轉動，底線張力變
強，向左轉動，底線張力變弱。
• 使用化纖縫紉機線時，請把張力稍稍減弱，
棉紗線時請稍稍加強。因為本機裝有防止
空轉彈簧， 所以裝上旋梭之後的線張力請
再調強 0.05N 左右。
直鎖眼縫
0.05 ～ 0.15N

鋸齒邊縫
0.15 ～ 0.3N

手拿從梭殼出來的線頭，輕輕地上下擺動時，梭殼就稍稍下降
To such an extent that bobbin case quietly comes down when
holding thread end coming from bobbin case and shaking it quietly
up and down.
手拿從梭殼出來的線頭，用稍稍強的力量擺動時，梭殼才下降
To such an extent that bobbin case barely comes down when
holding thread end coming from bobbin case and shaking it
somewhat strongly.
4. Threading the bobbin case
Rotating direction of bobbin and threading
(1)Fit the bobbin so that it rotates in the
direction of the arrow.
(2)Pass the thread through thread slit
① , then through under the tension
spring ② , again through thread slit ③ ,
and pull the thread from ④ .
(3)Threading at ④ for purl stitching is
different from that for whip stitching. So,
be careful.

5. Adjusting the bobbin thread tension
Adjust the bobbin thread tension as given
below when the bobbin thread is pulled
up at the position where thread slit ① of
bobbin case comes up.
•Turning tension adjust screw ② clockwise
will increase bobbin thread tension, and
turning it counterclockwise will decrease
the tension.
•Adjust the bobbin thread tension to
lower for synthetic filament thread, and
to higher for spun thread. The thread
tension is higher by approximately 0.05N
when the bobbin case is set to the hook
since idle-prevention spring is provided.
