In the case of looper thread breakage,
the looper thread twining prevention
mechanism is activated to trim the
looper thread before the thread twines
on the looper thread cam. In this way,
the looper thread twining prevention
mechanism prevents the looper
thread from twining on the looper thread cam. In addition, the looper
thread cam, which has been incorporated in the sewing machine, has
been changed so that it is mounted outside of the sewing machine. The
externally-mounted looper thread cam promises improved maintainability.
As a result of the commonality of components, commercially-available
components (presser foot, throat plate and needle clamp) are now
applicable and easily obtainable.
Seam quality is improved!!
Simplified maintenance mechanism
All of the sewing machines with
a thread trimmer are provided
with a direct-drive motor.
The direct-drive motor system has been
adopted by all of the sewing machines with
a thread trimmer. As a result, the sewing
machine starts up swiftly and promises
increased stop accuracy, thereby
demonstrating improved responsiveness.
In addition, the machine is no longer
provided with a V-belt. This means that the
adoption of the direct-drive motor is also
effective in the elimination of belt shavings. Power is directly transmitted
from the motor to the sewing machine, thereby contributing to reduced
power consumption. (This sewing machine reduces power consumption
by 27% as compared with the conventional models.)

The feed locus can be adjusted externally. The
feed locus is now adjustable in terms of the
vertical direction and horizontal direction, thereby
improving responsiveness to sewing materials.
Thanks to the new feed mechanism,
many different types of sewing are achieved.
Elastic material or delicate material can be
sewn with the presser foot kept slightly raised.
This effectively helps reduce the degree of
slippage, warpage and damage of the material.
Micro-lifter mechanism
It is possible to finely adjust
the differential feed amount
to a best-suited value for the
material to be used.
The differential feed ratio is
constant even if the stitch
length is changed.
Differential-feed micro-adjustment
mechanism
It is provided with many different sewing-related mechanisms which contribute to
improved seam quality, such as the new feed mechanism, and differential-feed
micro-adjustment mechanism. In addition, the machine is provided as standard with
a looper thread twining prevention mechanism for improved maintenance.
The MF-7900 Series is a newly developed
coverstitch machine provided with lots of
mechanisms for improving the seam quality.

JUKI's dry-head technology
protects sewing products from being stained with oil.
With the excellent functions inherited from the MF-7900 Series, the MF-7900D is provided with a dry frame
mechanism to eliminate the cause of oil stains. Stain removing work or re-sewing work is substantially reduced
by protecting sewing products from being stained with oil, thereby improving the quality of finished products.
The frame no longer requires oiling.
Dry-head technology has materialized
a frame which does not need oiling.
Environmental consciousness
Dichlorofluoroethane (HCFC-141), which is
generally used in oil stain cleaning fluid, is included
in those chemicals which need to be reduced, as it
is a substances that can harm the ozone layer.
Since oil stains on sewing products are reduced, the quantity
of the use of stain remover generally used in sewing plants
can be reduced.
The needle bar mechanism and spreader mechanism have been applied with a
special surface treatment.
JUKI's unique special grease is used for lubrication. Grease-filled bearings have
been adopted for the crank rod. These allow the machine's frame mechanism to
demonstrate outstanding durability without being oiled.
Unlike the conventional models, the oiling mechanism inside the frame has been eliminated.
As a result, oil does not leak from the needle bar, presser bar or spreader shaft.

By changing over the needle bar stroke, penetrating force of
the needle as well as thread tension to fit heavy-weight
materials (fleece, blankets) can be obtained. The needle bar
stroke can be changed by adjusting the eccentric pin.

The needle thread tightening
mechanism helps produce
well-tensed seams even when the
machine performs short stitching.
The short stitch pitch can be
adjusted with ease.
This is a device for preventing the thread from coming undone at the end of
sewing. The device is able to sew condensation stitches by the number
specified as desired. It prevents the needle thread from being poorly tensed,
which is likely to occur in cases where the amount of condensation is
reduced.
