Assembling of the needle throwing motor and the needle bar
rocking arm
(Caution) When needle throwing motor is removed, proceed to
step 1. If not, proceed to step 6.
1. Install needle throwing motor on installing base with setscrews
.
2. Paying attention to the assembling direction, enter needle throwing
connecting shaft A to needle throwing rod and needle throw-
ing lever, rear , adjust it to the flat section, and tighten with set-
screws .
3. Paying attention to the assembling direction, enter needle throwing
connecting shaft A to needle throwing rod and needle throw-
ing motor drive arm , adjust it to the flat section, and tighten set-
screws .
4. Paying attention to the assembling direction, enter needle throwing
motor drive arm to the shaft of needle throwing motor , and
temporarily tighten screw at the position where both planes of
the top end of shaft and needle throwing motor drive arm align
with each other.
5. Install needle throwing motor installing base with setscrews .
6. Entering needle bar rocking arm (asm.) from the face plate sec-
tion, pass it through needle throwing lever, rear and looper drive
lever .
(Caution) When needle throwing motor is removed, proceed to
step 7. If not, proceed to step 9.
7. Loosen setscrew in needle throwing motor drive arm , make
needle throwing lever, rear come in contact with metal , and
tighten setscrew in needle throwing motor drive arm at the
position where it smoothly moves.
8. Temporarily tighten needle throwing sensor installing plate at the
center of the slot with setscrew .
9. Temporarily tighten needle bar square block base with setscrews
.
10. Attach felt together with needle bar cover and washer us-
ing setscrew .
11. Assemble the needle bar rocking base. "Refer to (3) Disassembling
and assembling of the needle bar rocking base and the needle bar
crank rod."
12. Loosen setscrews in needle bar square block base , move the
needle bar up and down to check whether there is any torque. Then
tighten setscrews
.
13. Attach needle, and align the needle with engraved marker line
A
on the machine bed when the needle bar is in the lowest position
(lateral direction). "Refer to (13) Adjusting the tongue stopper." At
this time, align the bottom edge of needle throwing connecting shaft
A
with the upper side of the slot of motor installing base . Then
taking the lengthwise thrust of needle bar rocking arm (asm.)
with needle throwing lever, rear
, tighten setscrew in needle
throwing lever, rear .
14. Align the needle with engraved marker line
A
on the machine bed
when the needle bar is in the lowest position. “Refer to (13) Adjust-
ing the tongue stopper” (lateral direction). At this time, move looper
rocking lever
to and fro at the position where the bottom end of
engraved marker line
A
on the machine bed is aligned with the
edge on the lower side of the slot of looper rocking lever B . Then
tighten setscrew at the position where the looper rocking lever
smoothly moves.
15. Make sure of the position of the needle and the yoke slide when the
needle bar is in the lowest position.
"Refer to (7) Disassembling and assembling of the looper rocking
link and the looper rocking shaft and (4) Adjusting the position of
the yoke slide."
o Assemble so that the components
smoothly rock without looseness.
o Needle throwing connecting shaft
A is the selective part. There
are four kinds from A to D. Select
an adaptable needle throwing
connecting shaft from among them
for use.
o Assemble so that the components
smoothly rock without looseness.
o Assemble so that the components
smoothly rock without looseness.
If the adjustment is improper, the
lateral needle throwing fails to
perform symmetrically.
o Assemble so that the components
smoothly rock without looseness.
If the adjustment is improper, the
lateral looper throwing fails to
perform symmetrically.
