a

剪线电磁铁用螺钉B和C来固定。

B

在安装时必须保证驱动板1与凸轮曲柄2之间的间隙1mm

c.电磁铁工作时, 凸轮曲柄3与凸轮曲柄2

之间会有0.5mm的间隙, 这是标准的情况—

如需调整可以如图26所示箭头方向滑动电磁铁安装架。

4.lnstalling the trimming solenoid  (Fig.  32) 

(1)The stoke of solenoid 

a.  The standard stroke  is 6.0mm 

b.  Turn the nut  (A) to adjust the stroke 

(2)1nstalling the solenoid 

a.Fixed the solenoid by the screws Band  C; 

b.  Be sure to  keep the  clearance  between  the 

driven plate  CD and cam lever  R  ®  1 mm; 

c.  When the solenoid  is active,  there should be 

a  0.5mm clearance  between the cam lever  L 

@  and  cam lever  R  ®·  If need to adjust,  please 

move the solenoid base shown  by the arrow. 

5、 安装剪线凸轮(见图33)

(1)在挑线杆位于最低点时。

(2)将剪线电磁铁开动向前旋转剪线凸轮1直到

接触滚柱, 然后固定凸轮。

(3)剪线电磁铁关闭, 使凸轮曲柄2回复到原始

位置, 这样凸轮与滚柱端面将会产生0.5-

1.0mm的标准间隙。

5.lnstalling the trimming  cam  (Fig.  33) 

(1) When  the」oystick is  at the  lowest point 

(2)Set the solenoid active and turn the
