The Efficiency of the Operation Has Improved

Prevents Bird's Nests

A downsized and flat control box can provide a larger leg space to be utilized. The efficiency of the operation has been improved. It will also help to alleviate a sense of fatigue of operators who have to sit in front of the machines in a fixed posture for long hours.

Standard motor and control box

Stabilized motor stop position at the time of thread trimming reduces the bobbin racing. This prevents the bird's nests. It is a big advantage when sewing the light materials.
