high speed flat bed inter lock machine
Reliance and endurance is improved
Working is easier for user`s convenience
Perfect mechatronics is embodied by attaching Fortuna III / IV
We realized a maximum sewing speed of 3.200SPM, which is the fastest in the world. And we thoroughly studied and analyzed all the sewing-related operation mechanisms regarding X-Y feed, thread trimming, wiper, pressing plate to bring the best productivity to the work site. You can clearly feel our product's quality difference from the existing backtack sewing machine after comparing products.


To save the time for inserting thread and safe for user and external shape, it is designed to use the cover conveniently.

As for the various sewing material, you can get better quality of stitch because of simple operation.

It can be adjusted lifting amount of presser foot caused by simple structure knee lifting for convenience of user.

The external shape is very simplified caused by placing the synchronizer in pulley and it is realized a stable synchronizer as detecting the signal of servo motor.

To protect viscosity of oil from lowering for high speed sewing, oil cooling fan is installed in the lower shaft. So it is possible to supply oil stably and improved the endurance of goods.

It can be possible to install small motor for option as selection of user. The small motor is installed simply on the sewing machine and is not used V- belt but timing belt. And it maintain a stable working condition by Fortuna IV controller.
Differential ratio is adjusted easily by differential feed adjusting lever and also the lever can be adjusted for sewing.
