十八、弯针相对机针的同步(图23) / The timing of looper in reference to needle (Fig.23)
机针在最低点时,弯针退到最后,旋松图示齿轮的螺钉进
行同步调整(如图23)。
The looper shall be moved backward to the lowest position
while the needle is at the bottom dead centre; loosen the screw on
the gear and make timing adjustment of the looper in relation to the
needle (refer to Fig 23.)
图23
Fig.23
十九、弯针的勾取量(图24) / Thread-guiding amount of the looper (Fig.24)
1、弯针的针尖到达机针的中心位置时,弯针针尖离机针上端的距离标准值是2mm,此时针杆下端线和针杆
下衬套下端面对齐。(如图24)
2、弯针的后退量约3.5mm。
3、机针孔和弯针孔的相对关系如图24所示。(左右弯针可以分别调整)
1) The standard value of the vertical distance of the point of the looper away from the upper end of the eye of the
needle is 2mm, then the graduation mark on the lower part of the needle bar shall be in line with the lower end of the
needle bar bushing, lower.(refer to Fig.24)
2) The value of the stroke moved backward by the looper is about 3.5mm.
3) The relation between the eye of the needle and the eye of the looper is indicated Fig.24.
(Note that the left looper and the right one can be separately adjusted.)

3.5mm
二十、弯针和机针间的间隙 / The clearance of looper and needle
保针架调整后,机针和弯针间应留有一定间隙,即用手指轻压机针,机针也不应碰到弯针针尖。如果间隙
太小了,机针的侧面与弯针针尖就会因互相碰撞而损伤。
After adjusting the needle guard, the clearance of a given value between the needle and the looper shall be kept
unchanged; the needle shall not touch at the point of the looper when it is pressed down softly. If the clearance is narrower
than usual, the side of the needle and the point of the looper are apt to incur breakage due to the impact of the needle side
against the looper point.

二十四、挑线杆线量调节板的位置(图28) / The position of the thread-amount adjusting plate
of the thread take-up lever (Fig.28)
针杆在最低点时,如(图28)所示,用挑线杆线量调节板挡
住面线,这样勾取面线时,面线环变大。
此外,针杆在最低处时,也有拉紧面线环的作用,通常
在使用较细的缝纫时,应把线量调节板降到最低点。
The thread-amount adjusting plate will retain the bobbin at
bottom dead centre; in such a way
to become bigger when the needle
the loop of the needle thread is to
thread is hooked. In addition to the foregoing there is afunction of
the tight pulling of the needle thread loop. The thread-amount adju-
sting plate usually reduces to the lowest point when a thread finer
than normal is used.
Note that take-up thread tension lever is another name for thre-
ad-amount adjusting plate.

二十五、中间导线钩(图29) / Frame thread eyelet (Fig.29)
中间导线钩的位置也关系到跳针现象发生,一般把下列位
置作为基准(图29)
棉线#80~#50
中间导线钩刻度2~3
棉线#30~#20
中间导线钩刻度3~4
化纤线#80~#50
中间导线钩刻度1~2
化纤线#30~#20
中间导线钩刻度2~3
图29
Fig.29
The improper-positioning of the frame thread eyelet my be the cause of occurrence of skipping stitch.
The following locations are generally regarded as criteria (refer to Fig29)
Cotton thread#80~#50
Graduation marked on the frame thread eyelet 2-3
Cotton thread#80~#50
Graduation marked on the frame thread eyelet 3-4
Thread of chemical fibre #80~#50
Graduation marked on the frame thread eyelet 1-2
Thread of chemical fibre #80~#50
Graduation marked on the frame thread eyelet 2-3
二十六、针板的调换(图30) / Replacement of throat plate (Fig.30)
单针链缝机的针板出厂标准规格为1/4" (6.4mm)。(图30)
改变缝线间距通常同时要更换:
1、针夹 2、活压脚 3、针 4、送料牙 5、摆动护针杆
6、卷边器左弯针和右弯针在1/8"~1/2"针板规格之内部通用。
针板宽度大时,除上述零件外还要调换推板和凸轮盖。
The sandard size of the throat plate in parts book, which is
1/4", equivalent to 6.4mm. (Fig.30)
stipulated by the manufactory, is
The replacement of the following components is ususlly needed
at the time when changing the gauge of double-row thread stitch.
