smaller sewing pitch and
they help prevent fraying.

Optimized floating presser foot for
long pile materials
A micro-adjustable type floating presser foot, which
can be slightly lifted to sew according to sewing
materials, is equipped as standard. This device is
ideal for controlling presser foot floating in materials
that stretch easily and materials with long pile. It
prevents damage to the material. In addition, articles
can be handled with ease even when sewing curves.
One of the needle bars can be stopped simply by changing the position of the
stop lever (select lever). Compared to the previous models, a stroke of the
stop lever has been shortened to optimum stroke and the weight of the lever
has also been reduced by about 10 %
so that easy operation is possible with
a light touch of the lever.
The setting can be returned to twin
needle sewing simply by pushing the
push lever plate. The push lever plate
can be removed from the front face of
the sewing machine and easily
replaced so that it can be adjusted to
the best position.
In addition, with the adoption of
center stop mechanism, the stop
lever automatically and accurately returns to the center position to prevent
setting errors when it is set back to the twin needle sewing.
