Don’t you have these kinds of trouble?


It is difficult to sew stretchable or flexible fabrics that have varying degrees of stretchability, such as mesh fabrics.


The difference in the skill of a new operator and a skilled operator will create difference in the quality of sewn products. This will cause the loss of the defective product.


We want to increase production while cutting costs down.

The LaRgo solves all of those kinds of trouble.

  • Easily performs seaming on fabrics have varying degrees of stretchability
  • Drastically reduces the operator’s burden
  • Lowers costs by reducing defective products

Smoothly advancing with you.

No matter what the circumstances, no matter the operator.

Needle and threads advance smoothly at the sewer’s own pace.
Stitching is straight and beautiful without worry.

This precise and soothing rhythm will
accurately guide those that follow.

LaRgo, with needle and thread, seams smoothly,
drawing on long cultivated technical skills and the daily genesis of imagination.

We move forward into the future together.

Thanks to the LaRgo!

The LaRgo can perform sewing easily and beautifully.

The LaRgo easily and beautifully performs seaming on functional fabrics that have varying degrees of stretchability, such as mesh fabrics and stretchable fabrics that are employed for sportswear and similar garments.
The operator does not require any special skills, such as the ability to perform sewing the fabric while stretching it properly. This flatseamer can maintain consistent quality on the finished products, regardless of the skill of the operator.
Accordingly, the loss of defective products is decreased and productivity is increased.

The LaRgo stands out by featuring a “right and left independent” differential feed adjustment mechanism.

A standard feed mechanism feeds the same amount of the fabric consistently.
The LaRgo has a differential feed ratio adjustment lever on the right and left sides independently, which means that the LaRgo can adjust the differential feed ratio separately for the right and left hand sides.
Thanks to this feature, the proper feeding amount can be set and you will be able to sew up the fabric as you like.

Thousands of thoughts from PEGASUS

Our thoughts to our customers

Visiting the work site This is PEGASUS’ traditional style when Pegasus develops our new products.
PEGASUS listens directly to our customers, and connects what our customers desire to how we develop our products.

The LaRgo was created from PEGASUS’ traditional style of developing our new products.

The sewn products we have seen in recent years will evolve in response to changes of the environment and the times. Regarding fabrics, new functions will be pursued, and new fabrics that did not previously exist will be developed one after another. Accordingly, the operator always requires new special skills when sewing a new type of fabrics beautifully.
However, there are always beginners as well as skilled workers at the work site.

Then what do we do, in order not to decrease productivity when all the operators seam new difficult-to-sew fabrics?

Taking an example,
When the operator seams form fitting sports tights, she/he has to perform seaming on fabrics that have varying degrees of stretchability.
The operator requires new special skills. In addition, the seams may be used as a design, so the operator has to sew up each fabric beautifully. To do so, the operator has to sew two pieces of fabrics while stretching one piece of the fabrics. In order to complete this operation, the operator is required to seam the fabrics while making well-skilled adjustments. If the operator perform this operation repeatedly every day, it will cause operator fatigue.

That is where the LaRgo comes in!

On the LaRgo, the right and left differential feed ratios can be adjusted independently. Therefore, the operator does not require any special skills, such as the ability to perform sewing the fabric while stretching it properly.
Anyone can sew the fabric easily and rhythmically, achieving beautiful products and increasing production.
We would like to help you proceed smoothly and enjoy your everyday operations. In order to support you realize these operations, we would like you to welcome, accept and experience the LaRgo, the industry’s first such technology and concept, from PEGASUS.

Why do we call the LaRgo?

~The unknown story of naming LaRgo~

Why do we give a nickname to the machine?

“Shall we sell a machine with a nickname?”
This idea came suddenly in summer, 2016 to the Sales Department.It seemed a shame to bury a machine equipped with the world’s first excellent equipment (a right and left independent differential feed adjustment mechanism) as one of subclasses. Taking this idea from a salesman, we decided to give this machine a nickname. This is the first trial in PEGASUS’ history.

* The nickname was decided as the “LaRgo.”
Why did we give this name to the new machine?

There were 100 candidates for the nickname when the idea started. We held meetings repeatedly, in order to decide the nickname.
The name “LaRgo” can be associated with a term in musical terminology that means “to play with the sound flowing. ”The key reason for this name was that the LaRgo comes from the initial letters of “Left and Right” included in the description of a left and right independent differential feed adjustment mechanism. In addition, the sound of“LaRgo” is good and easy to remember.

A face plate describes what the machine is like.

A face plate is like a machine name sticker that is stuck to each machine. The face plate is usually created by the department in charge. However, the face plate for the LaRgo is employed as one of the sales promotion tools. Therefore, the Sales Promotion Department also thought that this tool was important.
At first, we were planning to attach two face plates to the LaRgo, a face plate for the FS700P series and one for the LaRgo. However, the LaRgo is a flatseamer that has a unique shape. This means that the area is too small for these two face plates.
After much trial and error, the two face plates were united, and a one piece face plate only for the LaRgo was created.

Focusing on the design for the face plate

Every time each of 15 patterns was attached to the machine,
shooting a picture was performed, in order to repeatedly check the difference between the face plate on the real machine and that in the picture.

1. PEGASUS’ unique oil barrier technology

FS700P Series adopts the world’s first machine bed equipped with a completely enclosed needle drive mechanism.
FS700P Series is keeping high-quality and consistent stitches, and protects your important sewn products against oil stains, thanks to this high "Oil Barrier" effectiveness.
PEGASUS’ unique “Oil Barrier” technology protects your important sewn products from oil stains.


2.Pneumatic presser foot pressure regulator(PP)

The uniform and most suitable presser foot pressure is always achieved according to the fabric.
This feature prevents seam jamming on cross seam sections, damage to the fabric, and shining appearing on the fabric, so this feature contributes greatly to stabilization and an increase in quality.
In addition, the presser foot pressure can be expressed in numerical form. Therefore, setting the presser foot pressure correctly for each fabric is easy, and the knife overlap pressure can be reduced simultaneously, increasing the durability of the knife.

3.Presser foot lift (PL)

Pressing the treadle with the heel raises the presser foot.
Ease of operation decreases operator fatigue.

4.Needle/Thread lubricating device (HR)

The HR device helps the needle thread run smoothly through the machine, forming uniform stitches.

5.Thread chain cutter

A pneumatically operated device that cuts a thread chain.
No scissors are needed. Operating efficiency is dramatically increased.

6.Waste collector

This pneumatic device sucks up cutting waste generated during sewing, providing clean and comfortable working conditions.

7.Direct drive motor (DD)

Operators do not feel stress because of quick reaction when operation of machine running and stopping has been done.
Additionally it creates the best condition for the operation, since under the table is nothing to be disturbed.
