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.

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.

Sew together

• If the cutter has operated before the seam has been formed,	Zigzag

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.

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.

Standard

Zigzag sewing pitch

The zigzag pitch setting range has been made even finer. You can now select intermediate pitches which were previously impossible.
