挑线簧调节（图 16、17）/ Thread Take-Up Spring Adjustment（Fig 16 17 - Jack H2 Series Product Instruction Manual

15.挑线簧调节（图 16、17）/ Thread take-up spring adjustment（Fig 16 17）
挑线簧摆动幅度为 5～8 毫米。缝纫簿的缝料
（短针距）则要减弱挑线簧的张力放宽摆动幅
度，缝制特别厚的缝料则反之。
1、挑线簧张力调节
先旋松夹线调节座螺钉（A）, 夹线螺钉
（B）就能转动，顺时针转动时张力增加,反之则
减少，调节好后，仍将夹线调节座螺钉（A）旋
紧。
控制方法：
松开夹线调节座螺钉（A）, 将夹线螺钉
（B） ，逆时针转动，使挑线簧 C 的张力压缩到 0 ,
再把夹线螺钉（B）顺时针转动， 至挑线簧（C）
触及夹线调节止动缺口，然后， 夹线螺钉（B）
再逆时针回转二分之一转动角度即可，最后旋紧
夹线调节螺钉座（A） 。
2、挑线簧摆动幅度的调节旋松夹线调节座固
定螺钉（B） ，转动夹线器（C） ，调节其摆动幅
度，夹线器（C）顺时针转动，摆动幅度增大，反
之则减少。通常，机器在出厂前，挑线簧均已调
整妥善，只是在缝纫特殊的缝料或特殊的缝线
时，才需要重新进行调整
The swing amplitude of the thread take-up
spring is 5-8 mm. Sewing material for sewing book
(short needle Width), the tension of the thread take-up spring should be weakened to relax the swing range, and
the reverse is the case when sewing particularly thick sewing materials.
1. Thread take-up spring tension adjustment
First loosen the thread tension adjusting seat screw (A), the thread tension screw (B) can be turned, the
tension will increase when turned clockwise, and vice versa, the tension will decrease. After adjustment, still
tighten the thread tension adjusting seat screw (A).
Control Method:
Loosen the thread tension adjusting seat screw (A), turn the thread tension screw (B) counterclockwise to
compress the tension of the thread take-up spring C to 0, and then turn the thread tension screw (B) clockwise to
the thread take-up spring (C) Touch the notch of the thread tension adjustment stop, then, turn the thread tension
screw (B) counterclockwise by half the angle of rotation, and finally tighten the thread tension adjustment screw
seat (A).
2. Adjustment of the swing amplitude of the thread take-up spring. Loosen the fixing screw (B) of the thread
clamp adjusting seat, turn the thread clamp (C) to adjust its swing range, turn the thread clamp (C) clockwise, the
swing amplitude increases, and vice versa. Usually, the thread take-up spring has been adjusted properly before
the machine leaves the factory. It is only necessary to readjust it when sewing special sewing materials or special
sewing threads.
