THE RELATION BETWEEN NEEDLE AND REAR NEEDLE GUARD
I. 設定後導針器高度 SETTING THE HEIGHT OF REAR NEEDLE GUARD
針棒在行進路徑的下死點，後導針器的陵線正好對正針孔的中心線。
WHEN NEEDLES DESCEND TO THE LOWEST POSITION. THE RIDGE LINE (A) OF REAR NEEDLE
GUARD (B) ALIGN WITH THE CENTER OF THE EYE OF EACH NEEDLE. THE ADJUSTMENT OF THE
HEIGHT OF
REAR NEEDLE GUARD IS MADE BY LOOSENING THE SCREW.
J/K 設定後導針器角度及時序 SETTING THE ANGLE AND TIMING OF REAR NEEDLE GUARD
配合前節所述，結線鉤與右針中心交會時，後導針器必須將針朝前推約 0.2-0.3mm，使鉤尖與針的
間隙為 0-0.05mm，與中針輕輕接觸與左針間隙 0-0.05mm，為其調整法為放鬆鎖緊螺絲與曲柄螺絲，
設定後導針器到適當位置再鎖緊螺絲 C,D。
WHEN THE TIP OF LOOPER PASSES THE CENTER OF RIGHT NEEDLE. THE REAR NEEDLE GUARD
WILL SLIGHTLY PUSH THE RIGHT NEEDLE FORWARD ABOUT 0.2-0.3 mm. AND AT THIS TIME,
THE CLEARANCE BETWEEN LOOPER AND RIGHT NEEDLE IS 0-0.05 mm AND LOOPER WILL TOUCH
MIDDLE NEEDLE SLIGHTRY. AND THE CLEARANCE BETWEEN LOOPER AND LEFT NEEDLE IS
0-0.05 mm. THESE ADJUSTMENTS ARE MADE BY LOOSENING THE SET SCREWS (C) AND (D).
L. 設定前導針器角度及時序 SETTING THE ANGLE AND TIMING OF FRONT NEEDLE GUARD
當結線鉤與左右針中心交會時，前導針器與針之間間隙為 0-0.3mm，調整時放鬆固定螺絲 E，移動前
導針器到適當位置後鎖緊螺絲。
WHEN THE TIP OF LOOPER COMES TO THE CENTER OF LEFT
NEEDLE AND RIGHT NEEDLE,ADJUST THE CLEARANCES BETWEEN
THOSE NEEDLES AND FRONT NEEDLE GUARD SHOULD BE
0 - 0.3 mm. THE ADJUSTMENTS ARE MADE BY LOOSENING SET
SCREW (E) AND MOVE FRONT NEEDLE GUARD TO ITS PROPER
POSITION. THEN,TIGHTEN THE SET SCREW (E).
