1. When the front and rear momentum of
the looper has been adjusted, move the
respective looper bases
!1
,
!2
and
!3
,
and readjust the front/rear positions
of the needles (
4
,
5
and
6
) and the
loopers (
1
,
2
and
3
).
2. When the above-mentioned adjust-
ments are carried out, the throat plate

should be removed.
3. When the front and rear momentum
amount of the looper is small :
The amount of contact becomes large
between tips of the needles (
4
,
5
and
6
) and rear parts of the loopers (
1
,
2
and
3
) and this can be a cause of
needle tip being blunt.
4. When the front and rear momentum
amount of the looper is large :
The clearance becomes large between
tips of the needles (
4
,
5
and
6
) and
rear parts of the loopers (
1
,
2
and
3
) and this can be a cause of stitch
skipping.
