LK-1903BB
This new model is provided with two new functions; i.e., "bird's nest preventing function" and "shorter-thread remaining function". This is the world's first lockstitch button sewing machine provided with both of these two functions.

LK-1903B
The machine achieves sewing speed of 2,700sti/min. The machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time.

LK-1903B/BR35
With our original horizontal forced feed mechanism, the button carrier sets a button in position so that the operation is simplified. Furthermore, operator fatigue is reduced since what operator needs to do is only setting material and pressing a pedal.
