LOOPER AND SPREADER ADJUSTMENT
I m p o r t a n t :
Before making these adjustments, check adjustments of race Sheet 11 and for
equalizing - Sheet 12
The loopers are held in place with the
set screw
n
- if necessary loosen
these screws and adjust the loopers so
that there is a slight clearance (1/64“
of an inch) between them and the
needle when in positions shown in
Fig.1.
The spreader location is controlled
by spreader stops. These are set
with set screws as are the loopers.
When the needle is at its lowest
position, adjust these stops so that
the spreaders are in locations shown
in Fig. 2.
The position of the needle as the loopers and spreaders are backing away is as shown in Fig. 3. It is
important that the space between the needle and spreaders is equal for each spreader. This adjustment
can be made with nut
o
on connection
p
Figure 4.
Note: When the limit of the thread
p
is reached, an additional adjustment is provided as shown
in Figure 5 - loosen screw
r
and raise or lower crosshead
q
adjust again as in Fig. 4.
NEEDLE BAR ADJUSTMENT
Turn the R.H. handwheel (knurled rim) until the needle bar has risen 3/32” from its lowest point
and is in position shown. In this position the eye of the needle should be about 3/32” below the
looper as shown in Fig.6
To adjust to this dimension loosen the screws
s
in Fig. 7 and raise or lower the needle bar
t
to
suit.
