MF-7900D-H24/UT, MF-7900D-H25/UT

Semi-Dry Head, Cylinder-Bed, Top and Bottom, Coverstitch Machine (Hemming with Left Hand Fabric Trimmer, For Extra Lightweight Materials)
MF-7900D-H24/UT
MF-7900D-H25/UT (With Sliding Presser Foot)

The machine is best-suited for the hemming of stretchy new material such as T-shirts, underwear, and sportswear, etc. The machine produces seams with no semi-cylindrical swells by performing sewing while making the feeding lengths of the right and left needle threads equal. The sliding presser foot prevents the material hem from twisting during sewing and further eliminates oblique-feeding of the material in terms of its texture.

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.

Thanks to the new feed mechanism, many different types of sewing are achieved

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.

Micro-lifter mechanism

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.

Differential-feed micro-adjustment 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.

The looper thread twining prevention mechanism has been improved and is provided as standard for the sewing machine

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.

Commercially-available gauge components are applicable with no additional work

As a result of the commonality of components, commercially-available components (presser foot, throat plate, and needle clamp) are now applicable and easily obtainable.

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.)
