[51 Knife mechanism
[Upper knife mechanism]
(1) |
When the crank shaft 0 rotates in the direction of the arrow, the upper knife driving rod assembly @ |
|
moves up and down on the eccentric part of the crank shaft 0. |
(2) |
The upper knife differential arm@) connected to the upper knife driving rod assembly 8 oscillates. |
(3) |
The upper knife differential arm @) oscillates the attached upper knife holder 9 and the upper knife |
|
@). |
[Lower knife mechanism]
(4)The lower knife (9 is attached to the lower knife holder 6, and is engaged with the upper knife 0 via
the spring @).
The lower knife holder guide@) positions the lower knife <a, and guides the lower knife holder 6.

111 Feed mechanism (1)
[Differential feed mechanism]
Slide block
JGathering feeding
*The differential ratio is adjusted by changing the height of the slide block against that of the main feed shaft 0. To acquire a bigger differential ratio, change the height of the main feed shaft 0.
(1)The differential feed lever @) moves the slide block on the differential feed arm @ vertically via the differential link lever e and the differential feed adjust link@.
(2) The differential feed amount is transmitted to the differential feed bar fi via the differential feed link @), and the differential feed dog @) operates.
*For gathering feeding, the differential feed lever@) is set to lower position. For stretched feeding, the differential feed lever @) is set to upper position.

111 Feed mechanism (2)
[Stitch length changing mechanism]
Reference mark
(1) |
When the feed adjust shaft |
0 is pressed around the eccentric cam of the eccentric wheel assembly |
|
with a finger and the pulley |
@ is turned in the direction of the arrow, the tip of the feed adjust shaft |
|
0 enters part® of the eccentric cam. |
|
(2) |
The stitch length can be adjusted by turning the pulley while the tip of the feed adjust shaft 0 enters |
|
|
part® of the eccentric cam with the feed adjust shaft 0 pressed. |
|
|
It is convenient to align the graduations on the pulley@ with the reference mark on the belt cover@). |
* After changing the stitch length, it can be fixed using the screw.
