JUKI's unique

housed inside.

Teaching function

The number of 
stitches in 
a sewing area with 
one of the needle 
bars held idle, is 
automatically stored.

Optional panel: IP-110B

The machine is installed with JUKI's newly developed 

unique separately driven needle bars. When one of 

the needle bars is stopped, it is held in place with 

added stability. This mechanism demonstrates 

outstanding durability. The machine is able to run at 

the highest sti/min even when only one needle is in 

operation (the other needle bar is held idle). This 

feature totally eliminates a fundamental problem of 

2-needle bar lockstitch machines, which is how to hold 

either needle bar securely in an idle state.

Corner-teaching function (provided as standard)

To start corner sewing, the operator need only  press 

the right or left stop switch.  Then, the machine 

automatically  counts the number of stitches.  This allows 

the operator to concentrate on material handling. 

Upon  completion of corner sewing, the one-needle stop 

state is automatically reset.

Automatic feature (Optional panel : IP-110B and 

Auto lifter : AK125 are required)

To sew two or more corners continuously, it is possible to 

enter a sewing program on the IP panel to automatize a 

sewing sequence from the beginning of sewing to thread 

trimming (including sewing of two or more corners).  

As many as 20 steps of constant-dimension sewing and as 

many as 8 different corner patterns can be stored in one 

program.  In addition, various conditions such as the 

up/down position of the needle bars, up/down position 

of  the lifter, forward/reverse feed and automatic thread 

trimming  can be set on a step-by-step basis.

For sewing pockets on men's shirts, hip pockets on jeans and topstitching on collars, a corner sewing process is required without 

exception.  The machine is provided with a function for automatically or semi-automatically sewing the corner sewing process with 

ease.

The function for separately driving the needle bars is automatically reset (LH-4168-7, LH-4188-7)

Teaching function 

1.  Press the left-needle stop switch at point A to stop the left needle.   
2. Perform sewing with the left needle bar held idle until point B is reached. 

(The number of stitches is automatically stored in the memory)   

3. At point C, the left needle, which has been held in an idle state, is 

automatically released. 

No resetting 
operation is 
required.
