。(圖33-1)
2. 當活動刀片往左移至左定點時，下勾針
線(C)須滑入活動刀片(A)之左邊刀口(D)
內。(圖33-2)
3. 活動刀片往右回移時，活動刀片右刀口
須勾住針線，左刀口勾住下勾針線，一

下切刀組與針線及下勾針線之關係：
1. When the Moving Knife (A) move to the left
which must be passed the loop (B) of needle
thread. (Fig 33-1)
2.
When the Moving Knife move to the left dead

(Fig.33-2)
3.
When the Moving Knife move to the right, the right
hook of Moving Knife must hooks the
needle
thread and left hook must hooks the looper thread
