Elastic tape foot This presser foot is used for sewing on elastic tape. In the same operation, the fa bric is trimmed and serged, and also gathe red by the contracting elastic tape. Setting the machine Set your machine to the 4-thread overedge seam. The seam width is determined by the width of the elastic tape. Working: Raise the needle to its uppermost position and insert the elastic tape sewing foot. Loo sen screw 1 so that brake 3 at opening 2 is opened by approx. 2 mm. Insert elastic tape 4 into opening 2 and pull it beneath the se wing foot so that it protrudes approx. 4 in ches (10 cm) behind the latter. Re-tighten screw 1. The more the screw is tightened, the greater the pressure brake 3 exerts on the elastic tape and thus the greater the gat her effect. Sew a test seam. The next step is normally to stitch the elastic tape towards the left with one of your machine's elastic (expandable) stitches (see illustration>. Sewing on a non-elastic tape prevents stret ching of the seams (e.g. shoulder seams> in stretch fabrics. Loosen screw 1 until the non-elastic tape can pass through opening 2 without hin drance. 65

Elastic
tape
foot
This
presser
foot
is
used
for
sewing
on
elastic
tape.
In
the
same
operation,
the
fa
bric
is
trimmed
and
serged,
and
also
gathe
red
by
the
contracting
elastic
tape.
Setting
the
machine
Set
your
machine
to
the
4-thread
overedge
seam.
The
seam
width
is
determined
by
the
width
of
the
elastic
tape.
Raise
the
needle
to
its
uppermost
position
and
insert
the
elastic
tape
sewing
foot.
Loo
sen
screw
1
so
that
brake
3
at
opening
2
is
opened
by
approx.
2
mm.
Insert
elastic
tape
4
into
opening
2
and
pull
it
beneath
the
se
wing
foot
so
that
it
protrudes
approx.
4
in
ches
(10
cm)
behind
the
latter.
Re-tighten
screw
1.
The
more
the
screw
is
tightened,
the
greater
the
pressure
brake
3
exerts
on
the
elastic
tape
and
thus
the
greater
the
gat
her
effect.
Sew
a
test
seam.
The
next
step
is
normally
to
stitch
the
elastic
tape
towards
the
left
with
one
of
your
machine’s
elastic
(expandable)
stitches
(see
illustration>.
Sewing
on
a
non-elastic
tape
prevents
stret
ching
of
the
seams
(e.g.
shoulder
seams>
in
stretch
fabrics.
Loosen
screw
1
until
the
non-elastic
tape
can
pass
through
opening
2
without
hin
drance.
