Standard zigzag stitching machine
LZ-2280N
The standard zigzag stitching machine creates softly finished
seams. The needle rocking mechanism is provided with a
triangular cam which helps produce beautiful seams with
consistency.
Fagoting machine
LZ-2285N
The pressure provided by the left- and right-hand sections of the
fagoting holder can be separately adjusted in order to prevent an
uneven material feed.
The hook driving shaft offset mechanism assures
trouble-free and consistent zigzag stitching
The machine is equipped with a hook-driving shaft-offset mechanism
which places the hook-rotating shaft off-center from the center of
zigzag stroke of the needle. This mechanism allows the blade point of
the hook to catch the needle thread every time regardless of the needle
throwing direction. As a result, the machine is immune to sewing
troubles such as stitch skipping and thread breakage, annoyances likely
to occur with the conventional machine, especially when the needle
throws to the right.
State of the conventional machine
Left Right
Needle
Blade point
Locus of the blade
point of the hook
The position at which the blade point of
the hook catches the needle thread is
different between the time when the
needle moves to the right and when it
moves to the left.
LZ-2200 Series
Left Right
The position at which the blade point of
the hook catches the needle thread
becomes almost uniform by offsetting the
hook driving shaft.
Standard wider zigzag stitching machine
LZ-2281N
Two kinds of gauges can be selected in accordance with the
application of the machine: an A-type gauge with a zigzag width
of 5 mm, and a B-type gauge with a zigzag width of 8 mm. The
needle rocking cam is provided with a triangular cam which
helps produce beautiful seams with consistency.
3-step zigzag stitching machine
LZ-2286N
The maximum needle throw is 10 mm.
The needle rocking mechanism means a higher degree of
accuracy, thereby leading to a very high performance.
Greater durability is secured by preventing
the hook from heating up when the
machine is running at high speeds
The inner hook is finished with titanium to keep it from
becoming hot. The machine requires only a very small
quantity of oil. This prevents oil stains on the material and
the improves durability of the hook. In addition, the hook
configuration is carefully designed to avoid needle
breakage.
