The machine runs at a sewing speed of 2,500rpm ญญญญ Faster than any other shape-tacking
machine anywhere in the world. In addition, the machine is fully equipped with state-of-the-
art features such as a higher presser foot lift, a double-capacity shuttle hook, and a direct-
control machine head that ensures quick response and an accurate stop position. The top
model in the LK series, the LK-1930 is JUKI's first shape-tacking machine to incorporate a
main unit input function equivalent to that equipped in our automatic sewing machines.
These rich features support the machine's high-speed sewing performance and increased
productivity. With its large sewing area that matches a wider range of use, its hand pulley,
and its highly operable and easy-to-understand operation panel, the machine delivers to the
user dramatically improved operability.
The LK-1910 Series shape tacking lineup is on the cutting edge ญญญญ a pioneer in a new era of
shape tacking.

LK-1930 (PROVIDED WITH AN INTERMEDIATE PRESSER AND INPUT FUNCTION)
The LK-1930 is provided with an input 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 input
through the operation panel.
LK-1930 (Table stand is optionally available.)
Abundant input functions enable the machine to respond
to the sewing requirements of all sewing patterns.
qWith its automatic correction feature, the machine can
enlarge/reduce patterns without deforming them.
q Ample storage capacity: maximum of 360,000 stitches on one floppy disk and 691 patterns
on a hard disk.
An EEP-ROM may be used.
q A maximum of 20,000 stitches can be input per pattern. With this large storage capacity, the
machine supports embroidery patterns with large numbers of stitches.
q Functions that are frequently used in programming works such as normal sewing (linear
sewing and spline sewing), point sewing, jumping, and thread trimming can be allocated to
specific keys mounted on the operation panel. The use of these keys reduces the time
required for data entry.
[Major input functions]
q Creation of linear, spline, arc, and circular stitches.
q Creation of various kinds of zigzag stitches, offset stitches, double-forward stitches, double-
reverse stitches, automatic back-tuck, condensation stitches, overlapping stitches, etc.
q Arrangement of move, copy, erase, and symmetry functions.
q Mechanical command to actuate the tension controller No. 3, changes in jump speed,
changes in sewing speed, etc.
q Data can be input using function numbers.
