3. 上勾針與下勾針之關係
當上下勾針相交時，兩勾針盡量接近，但不
可磨擦或碰撞，其間隙 A 點為 0.5mm B 點
為 0.2mm。( 圖 32)
4. 調整針與護針片之間隙
(1) 調整後護針片的方位
當下勾針尖移至針中心點時，後護針片①輕
觸車針，兩者之間間隙為 0mm。調整方式
為放鬆螺絲②移動後護針片①以調整之。
( 圖 33)
(2) 調整前護針片的方位
當下勾針尖移針中心線時，前護針片 ③ 與
針之間隙為 0.05mm ~ 0.10mm。調整方法
為放鬆螺絲④，並移動前護針片③以調整
之。( 圖 33)
5. 針與護針片之關係
(1) 當下勾針由左向右至針中心時 ( 雙針以左
針 ) 針與後護針片之間隙為 0~0.05mm。
(2) 當針在下死點時針與前護針片之間隙為
0.1~0.2mm。( 圖 33)
3. Relation between the upper looper and the
lower looper
When the upper and the lower loopers
meet, they reach each other as close as
possible, but should not rub or hit each
other. The clearance of point A is 0.5mm
and the B point is 0.2mm. (Fig.32)
4. Adjust the clearence between the needle
and the needle guard.
(1)Adjust the rear needle guard
When the tip of the lower looper moves to
the center of the needle, the rear needle
guard touches the needle gently. The
clearance between these two is 0mm.
Adjusting manner is to loosen the screw
② and move the rear needle guard ① to
adjust. (Fig.33)
(2)Adjust the front needle guard
When the tip of the lower looper moves
to the center of the needle, the clearance
between the front needle guard ③ and
the needle is 0.05mm~0.10mm. Adjusting
manner is to loosen the screw ④ and move
the front needle guard ③ to adjust. (Fig.33)
5. Relation between the needle and the needle
guard
(1)When the lower looper moves from left to
right, to the center of the needle (The left
needle is main while using double needles),
the clearance between the needle and the
needle guard is 0~0.05mm.
(2)When the needle is at the bottom dead
point, the clearance between the needle
and the needle guard is 0.1~0.2mm.
