Button sewing clamp kit for LK-1900 (Computer-controlled bartacking sewing machine)

This is a conversion kit from a bartacking machine to a button sewing machine.

Various button sizes can be supported. (Outer dia. 8 to 21 mm, thickness 1 to 4.5 mm can be sewn up to a hole spacing of 4.5 mm) Since the presser foot pressure is concentrated on the tip of the button clamp jaw lever, sewing defects due to displacement of the material are eliminated.Since the presser foot operates vertically, there is no deviation of the button center position due to the thickness of the material.
