SPS/B(A)-2516-HS-22
1) Specification
It is the same as the specification of SPS/B(A)-2516-HS-20.
2)
Adjusting the angle of upper feed plate
(both right and left)
When the upper feed plate (both right and left) is
parallel with a needle plate, pressure to press down
the sewing materials of the front side of upper
feed plate is insufficient. In that case, keep the
upper feed plate (both right and left) 3mm above
surface of the needle plate.
▶ How to adjust
ⓐ After loosen a cramp fixing screw ① of feed
plate and linking nut ③, turn the linking
screw ② clockwise, the front side of upper feed
plate comes to descend.
ⓑ After adjusting angle, fasten the cramp fixing
screw ① of feed plate and linking nut ③.
[Fig. 63]
3) How to adjust the ascending and descending velocity of upper feed plate
A. As shown in Figure63ⓐ, clockwise turn the holder② of pressure-reducing valve① including the solenoid
attached to the bottom of table, then the ascending speed and supporting pressure upon ascending get
increased. Counter clockwise turn it, they get down. Adjust the proper speed and pressure, and fix it
with a fixing nut③ (Initial Pressure Upon Delivery : 2.0~2.5㎏f/㎠)
B. As shown in Figure63ⓑ, clockwise turn the holder⑤ of speed controller④, the its descending speed gets
reduced. If counter turn it, the ascending speed gets increased. Then adjust the proper speed to fix with
a fix nut⑥.
