Mechanical button holer
Gives perfect sewing finishes
Stable zigzag seams even at high speed
A new needle zigzag mechanism (patent pending) reduces the effect of
vibration from upper shaft rotation on the needle bar, so that stable and
accurate needle zigzagging is obtained even at high speeds. When
sewing speed has been changed, a knife is not used to trim the thread.
The cutter space does not change, further making sure that the finish is
attractive.
Adjustment of zigzag width balance is possible
The left and right stitch width ratio for buttonholes can be set on the operation
panel.
Under lay
Up to four pattern can be combined and sewn together.
Rectangle
• Effective for preventing material from stretching.
• If the seam is hidden and the width seems small, sew 2-3
underlays to make the material look more voluminous.
• Because the material can be move slightly up to five times,
the seam flexibility is maintained and the button hole strength
can also be increased.
Sew together
• If the cutter has operated before the seam has been formed,
the hole made by the cutter is sewn up beforehand.
• The pile of fluffy fabric is pressed down before sewing, so
that the buttonhole finish looks more attractive.
Saw shape
• This is useful for preventing dimples from forming during bar
tacking.
• It is also effective for strengthening the buttonholes to stop
the seam from unravelling, which can often happen with
materials with coarse weaves.
Zigzag
• Effective for preventing seam from unravelling.
Selectable cutter operation
The operation of the cutter can be set to one of four timings (front knife, center
knife, rear knife and front + center knife). When the front knife setting is used, the
rough edges are hemmed by the buttonhole stitches after cutting, thus providing
a more attractive finish. When “Feeding when cutter operating” is set, only the
feed mechanism operates after sewing and the cutter moves to the specified
position, so that the button hole can be cut right up to the front backtacking.
Two-cycle sewing
When set to two-cycle cross sewing, the zigzag stitches sewn
during the first and second cycles do not overlap with each other,
so that the sewing pitch appears finer and the finish looks even
more attractive.
Prevents dimples at the rear tack
Selectable rear tack vector shape prevents dimples at the rear tack
section when not using an underlay.
Zigzag sewing pitch
The zigzag pitch setting range has been made even finer. You can
now select intermediate pitches which were previously impossible.
