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.
