● The machine ties a secuare knot to prevent the finished seam
from coming undone from the last stitch. Since the knots are
firmer than conventional knots, the hardly ever come undone.
Even if the last stitch comes undone, the thread is not likely to
come off, so the risk of losing buttons is dramatically reduced.
● 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.
