NA-11 series are for sewing heavy-weight materials
MECHANISM OF AUTOMATIC THREAD TRIMMER
The automatic thread trimmer achieves consistent thread trimming regardless of thickness of the thread, i.e., from thin to thick thread. The machine has adopted the rotary thread trimming mechanism which matches, in particular, design stitch with thick thread .
NEEDLE THREAD CLAMPING DEVICE
The needle thread device is standard equipment. As a result, the needle thread at the start of sewing does not come out on the cloth. Operators use scissors less often and can prevent damage to the material caused by thread picking.
The machine achieves a longer distance from machine arm to needle by adopting a high long arm. This means the machine dramatically increases workability when sewing large products such as sofas and car seats.
The LED light is located on the underside of the arm jaw. It reduces operator fatigue and improves work efficiency.
The machine's powerful top & bottom feed demonstrates its performance when sewing leather and heavy fabric. The lift of the presser foot is as high as 16 mm.
HORIZONTAL-AXIS FULL-ROTARY DOUBLE-CAPACITY HOOK
reduce the frequency of bobbin thread replacement, thereby promising sewing work with efficiency. This hook is also helpful not only when sewing with thick thread but also when sewing a long seam length.
