DigiFlex Feed Direct Electronic Feed Control
DigiFlex Feed, which is world’s first equipped on S-7300A and highly evaluated in the market, digitalizes feeding system and resolves various sewing troubles without adjustment work.
Optimization of fabric feed timing by changing feed motion of DFF
Fabric can be feed at an appropriate timing so that needle won’t break even during thick material sewing
Change from mechanical control to stepping motor control by equipped DFF
Compared to conventional mechanical control, the stepping motor control makes the response of reverse sewing quicker and reduces needle breakage.
Equipped with needle prevent breakage function while reverse sewing
Sensing needle position and controlling proper feed timing that prevent from unreasonable reverse sewing as needle breaks automatically.
