J00 J01 C00 C01
Projection of the arm frame of the machine head has been reduced. In
addition, the cloth cutting knife is located closer to the operator side as
compared with the conventional model. Viewability, when placing the
material on the sewing machine, is improved, thereby contributing to
improved workability. In addition, the thread clamp mechanism of the
needle thread clamp (optional) has been improved for better viewability.
The surface onto which the material is placed is flattened (for the machine
with an overall thread trimmer). The material can, therefore, be placed on
the machine with ease to improve workability.

An LED light is provided as standard on the underside of the jaw of the
machine head. The area around the needle entry is thus brightened to improve
workability.
A retractable bottom cover is
adopted. Daily maintenance
(threading, adjustment of the
looper thread, cleaning, etc.)
can be carried out without
raising the machine head.

MEB-3810J-01A-A1/MC-621ES/JTE01
Improved viewability around the needle entry JUKI's unique active tension
Two different thread trimmers are
prepared, i.e., the overall thread trimmer
and the needle thread trimmer
The machine is provided as standard with an LED light
Achievement of lower vibration and lower noise
Retractable bottom cover
Ease of placement of the material on the machine is increased
For the needle thread tension control, JUKI's unique
active tension mechanism is adopted to electronically
control the needle thread tension during the stitching
cycle. As a result, improved seam quality is achieved. In
addition, the sewing capabilities have been improved
to prevent stitch skipping, as well as to produce
well-tensed seams.
Two different thread trimmers are prepared. One of them
can be selected according to the customer's needs.
The overall thread trimmer has been newly designed
putting importance on productivity. It promises thread
trimming without fail and trims the thread in a short time.
The operator is no longer required to carry out fine
adjustments of the thread trimmer when changing the
sewing length.
A sewing machine with a needle thread trimmer has
been newly added to the MEB Series in response to
customer needs.
Quality improvement
The MEB-3810 reduces the machine time by approximately 22%*
due to its maximum sewing speed of 2,500 sti/min and its
speed-up cloth cutting knife, thereby demonstrating increased
productivity.
Then newly adopted direct-driven main shaft by means of a
compact AC servomotor not only achieves enhanced
responsiveness, but also achieves both reduced noise and
reduced vibration. In addition, the machine has adopted an
air-driven cloth cutting knife which promises excellent
responsiveness and operates faster than the conventional knife.
Machine time is substantially reduced
Adoption of a direct-driven main shaft and a revamping of the curve sections
of the thread take-up cam and looper cam contribute to remarkably reduced
vibration and noise. Vibration has been reduced by 7.7dB* and noise has
been reduced by 1.5dB* as compared with the conventional model to
produce this operator-friendly machine.
Condition: Measured at the maximum sewing speed
(MEB-3810: 2,500 sti/min; conventional MEB-3200: 2,200 sti/min)
The cloth cutting knife for the conventional MEB-3200 can be installed on the MEB-3810 by using a spacer (optional). The part number of the spacer is 40115728.※1
The knife guard for the conventional MEB-3200 can be installed on the MEB-3810 by using a spacer (optional). The part number of the spacer is 40115639.※2
Condition: Number of stitches: 21 for the straight section (one side),
11 for the eyelet section; knife length: 22 mm
