⑵ 讓夾線動作，可以保持縫製開始的穩定縫
製，可以把機針調整短，因此布料的上線纏
線現象變少。 但是，對於為了漂亮地捲進
上線但是縫跡長度不足的圖案等，布料背面
有可能挑出上線，請參考下列事項適當地選
擇有無夾線功能。
1）縫製長度短（約 10mm 以下）時，把機
線調短， 但是有時也出現鬍鬚狀情況。
⑶使用布料不與針板②緊密接觸的下板①時，
有可能發生上線鬆弛、不管線長度如何布料
背面均捲入上線的現象。

(2) It is possible to adjust needle thread
shorter by making the needle thread
clamp work while holding the stabilized
sewing at the start of sewing and the
gathering (bird's nest) of needle thread
on the wrong side of material can be
lessened. However, for the pattern which
the stitch length for neatly rolling in
needle thread is short, needle thread may
protrude from the wrong side of material.
Select with/without thread clamp referring
to the item below.
1) When the sewing length is short (less
than approximately 10 mm), the end of
needle thread may protrude like beard
even when adjusting needle thread
shorter.
