控線之調整
C
1. 控線強弱必須根據車縫布料種類,厚薄,線
及縫距等不同,而做不同之調整。( 圖 9)
2. 將控線鈕順時針方向旋轉時,線越緊,線張
力越大;反之則越鬆,線張力越小 ; 張力超
過規格強度時將會引起斷線和跳針現象。
3. 調整線張力依據使用之線與布面不同,例如:
需調整較大之線張力 - 厚布或棉線。
需調整較小之線張力 - 薄布或伸縮尼龍線。
4. 針控線桿之調整 ( 圖 11)
針線控線桿 (B) 依縫線使用種類來選擇使用
之狀態,放鬆螺絲 (A) 將 (B) 上下移動調整,
在使用伸展性大的縫線時,將 (B) 上移,則
針孔處之線環就會變大,以利勾線。
5. 轉動手輪使針捧位於最低位置時,針線控線
桿 (A) 必須成水平狀態,必要時要放鬆螺絲
(B) 調整之。( 圖 9)
