Siruba 747K-514M5-23/BK

Features

Patented high efficient & energy-saving direct-drive design (700KD)
– Integrated machine frame design.
– Built-in servo motor. Fast responsiveness, quiet, and low vibration. Easy speed setting.
– Built-in synchronizer, hand wheel is free of obstacle.
– Needle position function.
– High efficiency, energy saving, intergrated electrical system.

Sealed type direct drive needle bar mechanism
– Dust free and oil-leakage-free are due to entirely sealed needle bar section design.
– Direct drive needle bar system leads to high speed and long durability. No driving loss of connecting-rod-drive needle bar system.

Active lubrication system
Needle bar and upper looper mechanisms are applied active oil supply and entirely sealed vacuum oil return system. The new system exceeds the traditional oil supply of rope type and dropping type.

Patented feed dog mechanism oil proof system

Feed dog for extra light weight fabric (Optional)
E.g.: D201(standard):Teeth spacing 1.6mm ; D201A(optional):Teeth spacing 0.8mm ; D201B(optional):Teeth spacing 1.0mm

Optional presser foot fingers for better sewing performance: short finger for heavy fabric, long finger for
light fabric.

More user friendly features:
– Needle bar height adjustment without opening machine.
– Lower looper holder fine tune mechanism.
– Chainstitch fine tune mechanism: Open the rare cover to adjust stitch length easily.
– Needle plate thread groove leads to perfect loop.
– 5 cm height sewing area offers better cloth movement.

Electric-eye controlled waste vacuuming system(ET Device) (700KD Optional)
– Save energy. Reduce air compressor’s loading to 40% or more.
– Air suction is activated only when trimming thereby reduce the noise of air suction effectively.
– Does not suction light cloth into the suction trimmer. No need to overrun the seaming for suction trimming. Save
thread consumption and increase operation efficiency.
– Simple, easy, and user friendly.
