Computer-controlled, High-speed Shape-tacking Machine
Sewing area: 60mm (L) 100mm (W)
LK-1910
LK-1920
(with an intermediate presser)
The machine can shape tack at a maximum sewing speed of 2,500rpm,
dramatically reducing the cycle time.
With this feature, the LK Series models provide upgraded sewing
capabilities such as improved responsiveness to heavy-weight materials.
Select either S type(standard type) or H type(for heavy-weight materials)
to suit the use of your machine.
Settings for machine functions such as the sewing speed and bobbin
thread count can be easily adjusted via the operation panel, and cycle
sewing programs for the production of combined patterns can be entered.
The machine is provided as standard with an intermediate presser to
prevent the material from flagging, thereby promising beautiful seams.
Since height and stroke of the intermediate presser can be adjusted, quick
responsiveness to changes of material thickness or the number of layers of
materials is ensured. (LK-1920)
LK-1930
(with an intermediate presser and pattern programming function)
The LK-1930 is provided with pattern programming function equivalent
to that equipped in the AMS-210D computer-controlled cycle machine.
With its larger storage capacity, the machine supports diversified sewing
patterns. In addition, the sewing machine functions and patterns can
be programmed through the operation panel.
With its automatic correction feature, the machine can enlarge/reduce
patterns without deforming them.
Ample storage capacity: maximum of 360,000 stitches/691 patterns on
one floppy disk. An EEP-ROM may be used.
A maximum of 20,000 stitches can be input per pattern.
storage capacity, the machine supports embroidery patterns with large
numbers of stitches.
