I30调节摆压脚与小压脚交替提升量（图28)1
30- Adjusting the lifting amount of
presser feet (Fig. 28)
1摆压脚及小压脚的垂直方向运动：
＊摆压脚及小压脚是交替式的上下运动。
＊摆压脚及小压脚上升高度一般是相同的或是小压
脚的上升高度略低一些。
将挑线杆置千最下位置，放下压脚扳手，松开螺钉
＠使压脚升降前曲柄左，右移动来调节交替提升量
（右移：两压脚交替提升择趋千相同
左移：小压脚的提升量减小
）
1.Vertical movement of presser foot and walking
foot
*The walking foot CD and presser foot® move
vertically one after another
*Usually the stroke of walking foot and presser
foot is same or the stroke of presser foot is
slightly lower.
Place the thread take-up lever at the lowest
position, and lower the presser bar lifter. loosen
the screw@ and move the upper feed lifting cam
@.
Move it rightward to make the stroke of two feet
be equal
Move it leftward to make the stroke of presser
foot be smaller.
2．摆压脚及小压脚总提升量的调节：
根据缝料的不同要改变摆压脚，小压脚的提升蛋
C
先将偏心轮连杆螺钉O旋松，然后上、下移动来
调节该螺钉与压脚升降轴的中心距，中心距调小，
则各自的提升量都增加。
2.Adjusting the lifting amount of presser feet
Adjust the lifting amount of two feet to match the
materials to be sewn.
Loosen the screw@. and move the screw
upward to increase the lifting amount or move
the screw downward to decrease the lifting
amount.
3拼罢月三脚、小压脚前后方向间隙的调节：
＊为了在缝纫过程中，使摆压脚槽的前端与小压脚后端
面不碰撞，必须保持适当的间隙C (3mm左右）
旋松摆压脚前曲柄螺钉，然后上、下转动压脚摆
动轴
O
来进行调节。
3.Adjusting the forward/backward clearance of
the two feet
To keep the front groove of walking foot not
strike the rear of the presser foot, the clearance
of C must be kept about 3mm.
Loosen the screw of feed arm R, and then turn
the feed rock shaft@ to adjust.
4．摆压脚爰的调节（见A部）
＊送布牙送料量与摆压脚送料量之间的标准比率为
1 : 1 (同步送料）。
摆压脚的送料量可根据缝料不同进行调整，松开
螺母0．上下移动摆压脚滑块O来调节c
（向上：减小中心距L，摆压脚送料量减小）
向下：增大中心距L,摆压脚送料爰增大
4.Adjusting the feed amount of walking foot
(Fig. A)
*The standard ration of feed amount between
feed dog and walking foot is 1 :1
The feed amount of walking foot can be adjusted
to suit for the materials to be sewn.
Loosen the nut (J), and move the slide block@
Upward: decrease the distance L to make the
feed amount be smaller
Downward: increase the distance L to make the
feed amount be larger
