Attachment/device code
●
Device for sewing buttons without cross-over stitches Z025/AO14.
The machine automatically starts twice continuously by only depressing
the pedal once. This means that the machine can sew buttons without
the cross-over stitches required for hand sewn buttons.
●
The number of stitches can be quickly set to one of the
six different values, 6, 12, 24, 8, 16, and 32,
responding to the changing sewing specifications.
*
To set the number of stitches to 24 or 32, optional
parts (separately available) stated below are required.

●
Various kinds of attachments, which can do everything from sewing
flat buttons to attaching labels, are available. They can be used,
in combination with different subclass models, in a wide range of
applications.
●
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 button with accuracy.
●
The MB-373 comes with a compact-in-size thread trimming mechanism
which interlocks with the button clamp lifting lever.
The thread trimmer allows the machine to beautifully finish button
with no remaining thread after thread trimming. Furthermore, the
machine can sew large button which need thick thread.
