Single-thread, Chainstitch, Button Sewing Machine

MB-373NS Series

The 4-holed button sewing mode can be easily switched over to the 2-holed button sewing mode in accordance with changing sewing specifications. Furthermore, the button hole interval can be easily changed by operating the lever. The number of stitches can be quickly selected from among 8, 16 and 32 stitches corresponding to the change in sewing specifications. The machine ensures consistent sewing performance even when it runs at 1,500rpm. The unique speed-decreasing device reduces vibration when the sewing machine stops, thereby enabling the sewing machine to beautifully finish buttons with accuracy.
