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.
Beautiful stitching without puckering
OFF realizes appropriate thread tightening in relation with the fabric and reduces puckering.
Short remaining thread, (3mm) doesn't require after-cutting process
The new double action thread trimming mechanism cut's the thread right under the needle hole, realizing the short remaining thread at minimum of 3mm. The disposition of thread ends after sewing can be reduced thanks to the new system. (Premier Spec.)
Oil staining prevention
The closed oil tank enables clean sewing more than conventional model's that does stain sewing material. The minimum lubrication system prevents problems such as oil leakage and oil scattering drastically.
Easy operation with a simple panel
You can change the stitch length and sewing speed easily. In addition, it is possible to set the stitch length as a numerical value, and the reproducibility of sewing is improved.
Stress relief at reverse sewing
Because the reverse sewing is changed to motor control, vibration and noise are suppressed. It contributes a stress relief.
Reduction of hanging fabric
By arranging rubber on the back side which had been installed at the four comers of the bed of the sewing machine on the surface, it becomes easier to handle the fabric.
Productivity improvement with loT
NEXIO series are loT applicable models. The visualization by connecting sewing machine and computer technology enables the customer to analyze, manage processes and speed up productivity improvement and maintenance work.
Easy management and secure with data USB
Data transfer to other sewing machines and software upgrade can be done with USB memory easily.
