Features
  The machine has strong up-feeding drive especially for one-time sewing from general materials to ultra heavy ones.
  Simple & easy control mechanism of stitch length & reverse sewing function.
  Expecting to improve work-efficiency owing to rotary horizontal large hook (x2 Capacity). (KM-390BL)
  It realizes excellent working for round-type sewing by its cylinder-type bed structure, and enable us to choose the type of cylinder bed according to the size of sewing machine.
  Safety Ball-Clutch mechanism prevents sewing machine from being damaged for over drive.

1Needle, unison feed, lock stitch sewing machine with automatic thread trimmer (KM-560)
Thread trimming knife structured for high reliability and wide operating periphery
Because this machine is equipped with highly durable plane surfacing system which perfectly cuts all sized of thread ranging from thin to thick, this machine is widely used for general purpose
sewing as well as for heavy thick materials.
Simply structured thread trimming drive system
Superior anti-abrasive characteristics and high accurate knife operation. Simplicity of structure offers extremely easy
adjustment, assembly and disassembly procedures.
Solenoid controlled thread tension easing device (thread
trimming type)
The length of upper thread remaining in the needle after thread trimming is freely adjustable simply by simple adjustment of volume control in control box.
Simple solenoid type structure does not require cable connection.
Strong and stabilized upper feed movement
Constructed in block type upper feed movement structure, this machine demonstrates strong power in stepped sewing and even in heavy thick material sewing.
Accurate upper feed movement
The accurate movement of upper feed and gear action has eliminated puckerings and slip phenomena occurring on materials being sewn.
Feed back button offering functional variety
Sensitive touch-button operation allows smooth reverse stitching as well as needle bar movement from top to bottom or vice versa.
Larger by 2.5 Fold-Capacity hook installation
Work efficiency has been improved by installation of larger by 2.5 Fold-Capacity hook.
Convenient bobbin thread check system
Thread remaining in the bobbin can be verified easily through inspection windows installed on the right side of board.
Protection device for hook
Damage to hooks caused by overload occurring during sewing operations is prevented with safety device of a ball-clamp type.
Pressure control system operates as safety device by the simple bolt-adjustment.
Bed directconnection type,smoothly operating knee lifting
system
Knee lifting system not only operates smoothly, but raises the foot high.
No extra knee lifting system installation is required on table.
