Feature Benefit
Top Loading Jam-Proof
Bobbin System with Clear Cover
This mechanism incorporates a magnet-type vertical axis rotating hook
that ensures smooth, quiet, thread jam-resistant sewing. The bobbin
case floats above the hook, precluding thread jams.
Automatic Bobbin Winding Clutch
Needle bar automatically disengages when winding the bobbin, making
bobbin winding safer.
6-Segment Feeding System
This is a specially designed feed dog that ensures the fabric is picked
up and supported from the front of the presser foot to the rear. This
makes for much more accurate fabric feeding.
Box Feed
This is a feed dog motion that moves the feed dogs in a box motion,
rather than the historic arc motion. Box motion assures perfect feeding
throughout the entire feed process, as the feed dogs are always in
perfect and equal contact with the fabric and presser foot.
Drop Feed
A conveniently located lever, easily and effortlessly moved, will lower
the feed dogs for free-motion embroidery, monograms and for sewing
buttons.
Heavy Duty Metal Frame
The internal skeleton of the sewing machine. This rigid support holds all
the mechanisms in perfect alignment for perfect, skip-free sewing.
Direct Drive
The needle bar is geared straight from the motor, rather than from a
drive bar across the machine. This makes the machine more powerful
and durable.
On Board Storage Have easy access to accessories while sewing.
Snap-On Presser Feet Easily change presser feet without a screwdriver.
Thread Cutter
Located on the machine for precise thread cutting, eliminating the extra
step of cutting thread with scissors.
