Introduction
7.
縫製時的故障、原因和對策
7. Troubles and corrective measures
(sewing conditions)
4. 線切不斷
4. Threads are not
trimmed.
（僅限底線）
(Bobbin thread only)
◎ 更換固定刀。
◎ 把固定刀再弄彎一些。
◎ 調整動刀位置。
◎ 調整針和旋梭的同步。
◎ 高底線張力。
◎ Replace the counter knife.
◎ Increase the bend of the counter knife.
◎ Correct the position of the moving knife.
◎ Correct the timing between the needle and the shuttle.
◎ In crease the bobbin thread tension.

① 固定刀不鋒利。
② 針孔導向器和固定刀高低差小。
③ 動刀位置不好。
④ 最終針跳線。
⑤ 底線張力低。
① The counter knife is dull.
② The difference in level between the needle
hole guide and the counter knife is not
enough.
③ The moving knife has been improperly
positioned.
④ The last stitch is skipped.
⑤ Bobbin thread tension is too low.
1. 始縫時脫線
1. The needle thread
slips off at the start
of bar-tacking.
2. 常斷線
化纖線拉斷
2. Thread often breaks
or synthetic fiber
thread splits finely.
3. 常斷針
3. The needle often
breaks.
① 始縫時跳針。
② 切線後上線長度太短。
③ 底線過短。
④ 第 1 針的上線張力太高。
⑤ 夾線不穩定（布料容易伸長、線
不滑、線粗等）
⑥ 第 1 針的間距小。
① Stitches are slipped at the start.
② The needle thread remaining on the needle
after thread trimming is too short.
③ The bobbin thread is too short.
④ Needle thread tension at 1st stitch is too
high.
⑤ Thread clamp is unstable (material
is apt to be expanded, thread is hard to
slide, thread is thick, etc.).
⑥ Pitch at 1st stitch is too small.
◎ 機針和旋梭的間隙調整為 0.05 ∼ 0.1mm。
◎ 設定始縫時緩起動。
◎ 調節第 2 線張力器的浮線量。
◎ 把挑線彈簧弄強或把第一線張力盤的張
力減弱。
◎ 減弱底線張力。
◎ 弄大針孔導向器和固定刀的間隙。
◎ 降低第 1 針的張力。
◎ 降低縫製開始第 1 針的轉速。
（600 ∼ 1000sti/min 左右）
◎ 夾線針數增加 3 ∼ 4 針。
◎ 增長第 1 針的間距。
◎ 下降第 1 針的上線張力。
◎ Adjust the clearance between the needle and the
shuttle to 0.05 to 0.1 mm.
◎ Set soft-start sewing at the start of bartacking.
◎ Correct the thread tension release timing of
the thread tension controller No. 2.
◎ Increase the tension of the thread take-up spring, or
decrease the tension of the thread tension
controller No. 1.
◎ Decrease the tension of the bobbin thread.
◎ Increase the clearance between the needle hole guide
and the counter knife.
◎ Decrease the tension at 1st stitch.
◎ Decrease the number of rotation at 1st stitch at the
sewing start. (Extent of 600 to 1,000 sti/min)
◎ Increase the number of stitches of thread clamp
to 3 to 4 stitches.
◎ Make the pitch at 1st stitch longer.
◎ Decrease the needle thread tension at 1st stitch.
◎ 卸下用細磨時或銼刀磨平。
◎ 用銼刀磨，或換新。
◎ 調節布壓腳的位置。
◎ 卸下中旋梭，清除線頭。
◎ 減弱上線張力。
◎ 減弱挑線彈簧。
◎ 使用矽油。
◎ Take it out and remove the scratches using a fine
whetstone or buff.
◎ Buff or replace it.
◎ Correct the position of the work clamp foot.
◎ Take out the shuttle and remove the fibrous
dust from the shuttle race.
◎ Reduce the needle thread tension.
◎ Reduce the tension.
◎ Use silicone oil.
◎ 更換機針。
◎ 調節布壓腳。
◎ 根據縫製物選用適當的機針。
◎ 調整針和旋梭位置。
◎ 弄寬機針和挑線桿的距離。（23∼25mm）
◎ Replace the bent needle.
◎ Correct the position of the work clamp foot.
◎ Replace it with a thicker needle according to the
material.
◎ Correctly position the needle and the shuttle.
◎ Widen the distance between the needle and the wiper.
