Product features
-
Super-high-speed serging machine developed to achieve a simple structure and ease of use
The machine is applicable to the over casting of material fabrics cut into various jeans, pants and skirt shapes.

-
The machine comes in two different types
To fully support the operator so that he/she can carry out serging speedily, the machine comes in two different types; the long-table type and the short-table type which permits easy handling of the material.
The table shape of the short-table type machine permits easy handling of the material to perform serging of a long material even when the work space is small.
-
The machine is equipped with the super-high-speed overlock machine head MO-6904S
The machine achieves the high-speed performance of up to 8,000 sti/min to promise increased productivity. The machine performs serging according to the material used, is capable of sewing with reduced thread tension and promises consistent seam quality free from slip-off seams at curved parts of the material.

-
Flexible cloth guide
The cloth guide can easily be adjusted in height according to the material to be used without using a tool. It eliminates the troublesome changing of spacers.
-
Looper cleaner
A dust extractor is equipped as standard in the upper looper arm section where dust is likely to gather. It helps prevent dust from accumulating inside the cloth chip cover.

-
Micro-lifter device
The machine is provided as standard with a micro-lifter device which adjusts the lifting amount of the presser foot to the material thickness to achieve improved seam quality, while preventing puckering and material damage.

-
Air-blow table
The machine comes with an air-blow table, which issues a jet of air from its air nozzles at three locations to contribute to smoother handling of the material.

-
Easy-to-use stacker switch
The stacker automatically actuates according to the preset number of seams. In addition, the stacker can also be actuated by operating the large easy-to-press manual stacker switch.
