The AB-1351 is mainly intended for slacks and casual
pants.This model is not suited to the sewing of belt
loops on hard materials (thick denim in particular)
according to the shape of belt loops.
(The maximum thickness of a belt loop that can be
sewn is 1.8 mm.)

In the case of manual belt-loop attaching, the operator folds the edges of the
belt loops inside with his/her fingers to rough non-uniform dimensions and
sews them on garments.
In the case of the AB-1351, the operator is only
required to place the material on the machine and

with the AB-1351, it is not necessary to
cut the belt-loop material into certain dimensions,
there by contributing to labor-saving.

3. Twin-drived belt-loop feeding mechanism
The belt-loop drawing clamp and the belt-loop pushing roller operate
synchronously with each other (to correct their movements in relation to each
other), thereby ensuring accurate belt loop lengths even when using soft and
elastic materials.
(This mechanism is JUKI's unique twin-drive system.)

5. The machine is installed with the LK-1961, which
has one of the highest quality models.
The machine is installed with a machine head which has been
developed by modifying the highly-reliable LK1900A as the base,
In the case of sewing pattern No. 4, for example, three bar tacks
can be sewn with different sewing shapes, numbers of stitches,
thread tensions and sewing speeds.
(Maximum sewing speed: 2500 sti/min)
In addition, the feed mechanism is newly
controlled by an encoder to help reduce bar-tacking deformation .
The “grease joint (provided as standard)" used in the
oscillating rock shaft pin section can now also be used
in the main shaft crank.
Main features
6. User-friendly operation panel
By the IP-420 operation panel, the belt loop shape or sewing
pattern can be changed and the sewing positions and other
sewing conditions can be programmed with ease through the
operation panel. The operation panel supports 14 different
languages.:
Chinese(2kinds)・ English・French・ German・ Indonesian・
Italian・ Korean・ Portuguese・ Russian・ Spanish・Turkish・
Vietnamese ・Japanese
Number of bar tacking patterns stored in its memory: 9 kinds .
6 Linear bar tackings
:(12-, 15-, 21-, 28-, 36-, 41-stitches)
3 Zigzag bar tackings
:(28-, 36-, 42-stitches)
Size (X direction: 6 - 23 mm; Y direction: 0 or 1 - 3.2 mm)
The maximum number of
belt-loop patterns that can be stored in its memory: 99 patterns
Cycle sewing: Max. 20 cycles (30 patterns per one cycle)
The machine stores bar tacking shapes 200 patterns or 20,000
stitches at the maximum. It is possible to be created by the PM1 .

Main features
8. Insert belt loops from the front side!
Belt loops are to be inserted from the
front side of the main body of the sewing machine.
The operator is, therefore, able to visually check
the belt loop state whenever necessary during
sewing.
9. Oil stains on sewing products are eliminated.
The machine is installed with the modified semi-dry LK1900A .
The belt loop feeder unit uses a grease lubrication system (with JUKI
Grease A). This means that the sewing products are no longer
stained with excess oil.
(A grease run-out warning sign appears on the panel .)

8. Belt-loop drawer support device
[Part number :400-94294]
The belt-loop drawer support device pulls out, beforehand, the beltloop required for the subsequent sewing. It is particularly effective
when belt-loops are wound in the shape of a drum. This device
prevents any belt-loop length variation, even when using belt-loops
made of elastic material.
It stops showing an error message if belt loops become entangled.
Comparison with
competitive models
◎Major advantages of the JUKI AB1351
①
It is provided with 7-different sewing patterns to achieve higher flexibility.
②Main mechanisms have been computerized. This means that the time
required for adjustment is reduced without the need for operator skill.
③ It is also easy to return the adjusted values to the previous values.
④It helps increase productivity.
(One operator can attend two AB1351 units at a time.)
⑤The sewing position and belt-loop folding dimensions are accurate,
thereby contributing to consistent and improved quality.
