Semi-dry head, Cylinder-bed, Bottom Coverstitch Machine with digital type top feed/For hemming with left hand fabric trimmer
MF-7912 DRH24
MF-7913 DRH24
The MF-7900 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.
The machine is provided with the digital type top feed mechanism
This mechanism prevents problems, such as twist of fabric, uneven material feed, skew of grain, and stitch gathering on multi-layered sections of material, which are likely to occur when sewing elastic materials, thereby achieving stable seam quality.
Digital setting of the top feed mechanism
The digital setting of the top feed mechanism can be carried out with a jog dial with a control panel.
(Top feed amount can be adjusted and stored directly in memory.)
Reduction in setup time
The digital setting of the top feed mechanism enables easy adjustment of sewing even when the product to be sewn is changed, thereby reducing the setup time.
Flat and soft seams (H24)
The sewing machine produces seams with no semi-cylindrical swells by performing sewing while making the feeding lengths of the right and left needle threads equal.
