Minimal Lubrication

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 Sealing Technology

• Special seals installed at the ends of each bushing above fabric, to prevent excess oil from dripping onto fabric by wiping oil away from the surface of the moving parts
• Sewing cylinder area consist of a special oil wiper installed at the end of looper bar bushing, where oil is wiped away from looper bar surface as looper bar is exposed
• Oil is circulated rather than wasted. Excess oil that is being wiped is first stored in a felt. It is then collected by the force of the pump, cooled down and filtered for the next cycle of lubrication

Easy Maintenance

	Switchable Needle Bar StrokeNeedle bar stoke 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 SystemThe cam is located outside of the machine frame for easy adjustment and removal. Downtime to unwind looper thread in case it winds itself around the cam is dramatically shortened. Also, the cam can be exchanged easily according to different sewing conditions.
	Foot Lifter Lever MechanismThe outer lever (similar to the one for overlock machine) enables easy assembly and adjustment of foot lifter without removing top cover.

Highly Versatile

Active Thread Control
Yamato’s “Active Thread Control” makes ideal thread balance control to form any desired seam, with less stress given to each thread. Adjustment from soft to tight seam can be done simply and visibly to minimize required skills and downtime spent for addressing frequent changes of sewing conditions.

Wide Range of Seams
Active Thread Control supports a wide variety of seams from soft and elastic seams to tight seams. Results in tunnel-free finish
