Streamline Cylinder Bed Makes Operator’s Handling Easier, for Improving Quality and Productivity.
- Streamline Cylinder Bed Makes Operator’s Handling Easier!
- Active Thread Control supports ideal seam over wide range from soft and elastic seams for microfibers to tight seams for outer wears.
- Yamato "Non-stain" Technology minimizes the risk of oil stain, the most frequent cause of defects.
Streamline Cylinder Bed Makes Operator’s Handling Easier!
Streamline cylinder bed makes operator’s handling easier. Streamline may cylinder bed reduce setting, feeding and removing works when required with conventional cylinder bed interlock machines.
Yamato's signature Active Thread Control Technology
Active Thread Control supports ideal seam over wide range from soft and elastic seams for microfibers to tight seams for outer wears.
Yamato "Non-Stain" Technology
Yamato "Non-stain" Technology minimizes the risk of oil stain, the most frequent cause of defects.
Streamline Cylinder Bed Makes Operator’s Handling Easier!
Streamline cylinder bed makes operator’s handling easier. Streamline may cylinder bed reduce setting, feeding and removing works when required with conventional cylinder bed interlock machines.
Moreover, streamline cylinder bed helps you reducing defects and enhancing productivity by reducing operator’s tiredness.
Yamato "Non-Stain" Technology
Less friction, Less Lubrication
Much less lubrication than conventional machines are required thanks to high-tech mechanical parts dramatically reducing frictions.
The oil is pumped to needle bar crank area, all way through upper shaft. Thanks to "forced lubrication", very small, but stable amount of oil is always given to exactly where it is necessary, and ensures less risk for leakage while maintaining machine performance.
Special Seals Prevent Oil Leakage
Special sealing mechanism is installed on each bushing above fabric and sewing cylinder area.
These seals are designed to prevent oil excess from dripping on fabric, by wiping oil film away from surface of moving parts.
Excess Oil is Collected and Circulated
Wiped oil excess is collected by pump force to be cooled down and filtered for next cycle of lubrication.
Active Thread Control supports ideal seam over a wide range from soft and elastic seams for microfibers to tight seams for outer wears
Making ideal seams over wide range, Active Thread Control supports wide variety seams from soft and elastic seams to tight seams. Yamato Active Thread Control makes ideal thread balance control to form any desiered seam, with less stress given to each thread.

Versatility
Can be applicable for Covering, Hemming and Binding operations.
Easy Maintenance
Switchable Needle Bar Stroke
Needle bar stroke can be switched from 31mm(standard) to 33mm by simply turning an eccentric pin on the needle bar. This epoch-making system shortens the downtime for conversion to meet extreme change of fabric weight.
Looper Thread Take-up Cam System
The cam is located outside of the machine frame for easy adjustment and removal.
Downtime to unwind looper thread in case of it winds itself around the cam is dramatically shortened. Also, the cam can be exchanged easily according to different sewing conditions.
Openable Side Cover
Side cover is openable for easy feed dog height adjustment and cleaning.
New Foot Lifter Mechanism
The outer lever (similar to the one for overlock machine) enables easy assembling and adjustment of foot lifter with-out removing top cover.
