WORK CLAMP FOOT AND FEED PLATE 
FOR LK-1902B

 (for belt-loop attaching)

The sewing pattern best suited to the sewing product 
to be bartacked can be selected by single-key operation.

The machine is provided as standard with six different linear bartacking 
patterns. Since the sewing size can be easily changed, the optimal number 
of stitches and sewing size can be speedily selected according to the 
belt-loop width.  If the normally used patterns are assigned to the patterns 
keys, a desired pattern can be called up or changed with single-key 
operation.

The machine head has been designed 
with an emphasis on operability.

With its broadly curved feed bracket (presser arm), the machine permits 
easy placement of the material to be sewn.  The slimly shaped bed and 
head design that allows free space under the arm demonstrates greater 
operability in handling materials on the machine and continuous processes. 
These features contribute substantially to increased productivity in belt-loop 
attachment processes.

The machine ensures high-quality bartacks on eyelet buttonholes.

The machine is provided with a material-drawing mechanism which draws the right and left parallel portions of an eyelet 
buttonhole near to one another.

The machine performs bartacking with the right and left parallel portions of the eyelet buttonhole drawn near to one another 
after the buttonhole is clamped under the work clamp foot, thereby finishing highly durable and well-tensed eyelet buttonholes.

The sewing pattern best suited to the sewing product 
to be bartacked can be selected by single-key operation.

Three different sewing patterns are prepared to enable easy switchover of sewing sizes.  If the sewing patterns are assigned to 
the pattern keys on the operation panel,  the sewing patterns can be called up or changed with single-key operation.

The machine sews the most optimally suited bartacks on eyelet buttonholes on the front bodies of garments and straight 
buttonholes that differ in stitch number and size on jacket lapels, thereby improving the finished quality of sewing products.

The material drawing mechanism can be switched to ON/OFF.

The material drawing amount can be adjusted to 3mm at maximum. The material drawing mechanism can be switched ON/OFF 
in accordance with the setting of the memory switch.  With these features, the material drawing mechanism can be used with 
greater flexibility.

IP-420U should be ordered as a part.
[IP-420U : 40144886]

Operation panel provided with programmable functions

Functional settings, such as pattern numbers and needle thread tensions 
can be established through the operation panel with ease. Distance 
between holes in a button can be easily changed by means of pattern 
enlargement/reduction feature.

Input and edit data while observing the needle-entry points visually.

The operator can easily check the shape of the pattern displayed on the wide liquid crystal panel.

Make minor adjustments to data quickly and efficiently. Overall use is easier than ever before.

The memory storage capability of the main body of the sewing machine has been dramatically 
enhanced. Now the USB-ready main body of the sewing machine uses many different kinds of 
media. In addition to the Compact Flash card, the main body of the sewing machine is provided as 
standard with a USB connector. Now, data can be input/output to/from various kinds of media (SD 
(Secure Digital Card), CF (Compact Flash), SM (Smart Media), FD (floppy disks) etc.) by means of 
a USB thumb device and a card reader.

Standard sewing patterns can be assigned to pattern keys P1 to P50. Any of 
the sewing patterns assigned to the P1 to P25 pattern keys can be activated 
with a touch of the corresponding key. This means that workability is 
improved by assigning 25 sewing patterns that are most frequently used to 
those pattern keys.

As many as 99 different cycle sewing patterns, each of which 
combines a maximum of 99 different sewing patterns, can be 
stored in the memory.

The IP-420U is a new operation panel configured 
with a "input function" not available in standard panel.
