High-Speed, Flat-Bed, Top and Bottom Coverstitch Machine (Collarette Attaching)
MF-7500D-C11 (Semi-Dry Head)

The MF-7500 Series is a newly developed coverstitch machine provided with lots of mechanisms for improving the seam quality. 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.

C11 For collarette attaching.

This model is best suited for attaching collarettes on underwear, briefs, and knitwear. Ease of use is further improved by using the electromagnetic type tape cutter (TC16).

JUKI's dry-head technology protects sewing products from being stained with oil.

With the excellent functions inherited from the MF-7500 Series, the MF-7500D 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.

Feed longitudinal position adjustment mechanism.

The longitudinal position of the feed is adjustable. As a result, uneven material feed and puckering that are likely to occur when sewing products made of elastic materials such as foundations are reduced. This means that the machine promises improved responsiveness to elastic materials.

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.

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.

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.
