The machine comes with a newly developed needle clamp to increase the stability of needle-thread loops and to reduce untwining 

of the thread. The needle clamp works to improve the right and left seam balance and prevent thread breakage, in an idling 

stitching process, by changing needle threading according to the type and thickness of thread.

The machine is provided with a high & long arm which facilitates the handling of sewing products even when sewing large ones 

such as jeans. In addition, increased stop accuracy and excellent responsiveness, which are the most prominent features of 

the direct drive,  work in combination with the high & long arm to help eliminate operator stress, thereby increasing productivity.

The machine has the largest distance from needle to machine arm among any other similar models regardless of manufacturer, i.e., JUKI and its 

competitors.

New model of wire-type needle clamp
