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.) 图24 Fig.24 2mm 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. -9- From the library of: Superior Sewing Machine & Supply LLC jintex.in

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. 图28 Fig.28 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.
