EQUALIZING THE LOOPERS
The loopers
n
and
o
when properly adjusted
will assume the positions in Fig. 1 - with their
points on center line of needle on alternate
strokes after the needle bar has risen 3/32“ from
its lowest position.
To make this adjustment - remove the clamp
plates - remove the throat plate from the race -
turn the machine with the L.H. handwheel (with
handle) until the loopers are in front.
Turn the R.H. handwheel (knurled rim) until the
needle is at its lowest point.
Raise the needle slowly with this same
handwheel until the L.H. looper point
p
is in
position shown (Figure 2).
While in this position measure the distance that
the needle bar protrudes above the cap
q
with a
scale and make a note of this dimension.
Turn the R.H. handwheel again until the right
hand looper
r
is in position shown (Figure 4) -
and while in this position measure again as
above.
Important:
These two measurements must be the same for
the proper working of this mechanism.
To equalize this dimension, loosen screw
s
in
race and move crosshead
t
up or down upon
spindle
u
as required.
After this has been done - turn the R.H.
handwheel (knurled rim) until needle is in its
lowest position. Measure again at the cap as
above and raise the needle bar 3/32 of an inch -
with the needle bar in this position - looper points
should be as shown in Fig. 2 and Fig. 4.
If they are not- loosen screw
v
and turn the core
w
slightly in either direction with the special
wrench, until the loopers are in these positions.
Adjustment in direction of arrow advances the
loopers across the needle.
