Application and performance
The MD441, 641, 643 is an elastic lace feeder for attaching elastic lace to panties, lingerie and similar garments.
All you have to do is enter sewing data into the controller, then inserting and attaching elastic lace are just as easy as plain
seaming.
26 programs (items) from A to Z (kinds and/or sizes of garments) can be entered and stored. Up to five patterns per item
(sections to be sewn in a garment) can be entered and stored. Where to operate the tape cutter (at the start or end of sewing)
can be programmed in each pattern (1 to 5). In addition, up to seven steps (changing where to use fullness application and the
amount of fullness application during sewing) can be programmed and stored. When switching steps, you can select either
MANUAL (switching by the knee switch) or AUTO (switching by stitch counting) mode as you require.
Note : The tape cutter function is optional on MD441.
Feeding amounts and stitch counts can be
entered into up to seven steps.
The device can be used with only one step.

source (air compressor).
Connect air line 1(from the air source) to joint 2and then
fasten it with hose clamp 3. Then connect filter regulator 4
to solenoid valve 5with air line 6.
Note
●Be sure to insert air line 6into joints 7and 8as far as it
will go. Make sure air line 6cannot be removed from
joints 7and 8by pulling air line 6.
●To remove air line 6, pull air line 6while pressing release
ring 9straight to the depth.
Adjusting air pressure
Pull up knob 10 on filter regulator until it clicks.
Then set the air pressure at 0.5 Mpa (5 kgf/cm2).
●Turning 10 in the direction increases the air pressure.
●Turning 10 in the direction decreases the air pressure.
Draining the filter regulator
Drain the filter regulator before collected drainage reaches
the level 11 by pressing button 12.
CAUTION
CAUTION
Be sure to drain periodically. Otherwise, drainage will
flow into the solenoid valve and/or air cylinder, causing
trouble.
Note that drainage and air spout out downward.

Inserting elastic lace
CAUTION
CAUTION
Be sure to turn off the power when inserting elastic
lace. Be careful that your hands are not caught in the roller
when performing the procedure.

1. Insert the elastic lace 1into roller 2as shown in the
illustration.
2. Adjust guides 4and 5so that elastic lace 1can go
through them smoothly. To make this adjustment, fit the
left edge of the elastic lace to fixed guide 3exactly first
and move guides 4and 5as needed in the direction of
the arrows.
3. Adjust guide 6so that elastic lace 1can go through
guides 3and 6smoothly. To make this adjustment, fit the
left edge of the elastic lace to fixed guide 3exactly first.
Then loosen screw 11 and move guide 6as needed in
the direction of the arrow.
4. Open roller 2by pressing lever 7and then insert elastic
lace 1.
5. Adjust guide 9so that elastic lace 1can go through guide
8and 9smoothly. To make this adjustment, fit the left
edge of the elastic lace to fixed guide 8exactly first.
Then loosen screw 12 and move guide 9as needed in
the direction of the arrow.
Note
Insert the elastic lace so that it will form a straight line as seen
from the front of the machine.
6. Adjust roller 2pressure so that the elastic lace can be
fed properly. To make this adjustment, turn nut 10
clockwise or counterclockwise as required.
• To decrease the pressure, turn in the direction of (A).
• To increase the pressure, turn in the direction of (B).
Note
The above procedures are for reference. Use guide 13 as
required according to the characteristics of the elastic lace.

Adjusting the guides according to the width of the elastic lace
CAUTION
CAUTION
Be sure to turn off the power when inserting elastic
lace. Be careful that your hands are not caught in the roller
when performing the procedure.
1.Right lace guide 5is set at the factory according to
20 mm elastic lace.
Adjust guides 1, 2, 3, 4and right lace guide 5according
to the width of the elastic lace .
(see Fig. A)
2.For 20 - 38 mm wide elastic lace:
Loosen screw 6and move right lace guide 5to the
extreme right end.
Then cut the left end of right lace guide 5so that 38 mm
elastic lace can go through easily.
(see Fig. B)
W
WARNING ARNING
To prevent accidents when cutting lace guide (right) 5,
well-qualified technicians should perform the procedure,
being careful not to injure their fingers and/or hands.
3.For 38 - 92 mm (max.) wide elastic lace:
Replace right lace guide 5with lower lace guide
assembly 7.
Loosen screw 8and adjust guide 9according to the
width of the elastic lace.

Functions of the machine treadle/external switches
Machine treadle
･････Starts the machine.
CAUTION
CAUTION
Pressing the treadle starts the machine even while
the control panel is used to enter sewing data.
Knee switch
●In the MANUAL mode the machine goes to the next step
by pressing this switch.
●In the AUTO mode steps cannot be changed by pressing this
switch.
Finger switch (optional)
Pressing this switch operates the tape cutter.
Note
When you program the machine using the controller or if
ON is not selected on the AT function (see page 25) on
the function select mode, pressing the finger switch will
not operate the tape cutter.
Pressing the treadle with toes

The fabric detection sensor detects the end of the fabric at
the start of sewing so that the controller can count the num-
ber of stitches from the end of the fabric to a part of ruffling.
Therefore switching a ruffling operation is correctly done.
To adjust the sensitivity of the sensor
CAUTION
CAUTION
Well-qualified technicians should adjust the sensor
properly according to the fabric to be sewn. Otherwise the
tape cutter could get activated unexpectedly during sewing.
1.Turn on power switches 1and 2.
2.Ensure that no material is inserted when adjusting sensor
3.
3.Turn dial 4until the fourth from the left of indicator lights
6is turned on completely.
4.Turn dial 4clockwise slowly and stop turning dial 4until
the fifth light is turned on.
Check the indicator lights carefully if they are turned on/off
correctly with fabric or no fabric. (Confirm that the lamps
indicated by 6are all terned off when material is inserted.)
Adjusting the sensitivity of sensor
Note 1 : To sew special materials and/or extra light fabrics which the light from the sensor goes through, see below.
1. Turn dial 4until the third from the left of indicator lights
6is turned on completely.
2. Turn dial 4clockwise slowly and stop turning dial 4until
the fourth light is turned on.
Note 2 : Clean the reflector on the top surface of the needle plate. Otherwise malfunction may occur.
