MO-6900R

High-speed, Variable Top-feed, Overlock / Safety Stitch Machine-MO-6900R Series

The MO-6900R Series comes with a newlydeveloped feed mechanism that moves the top and bottom feeds separately. With the combination of the feed’s increased differential feed ratio and improved feeding capacity, the machine is able not only to prevent uneven material feed, but also to easily finish difficult processes, such as sewing different types of materials together, ruffling and piping.

Excellent bottom and variable top feed mechanisms

  • The locus of the top feed dog increases the surfaces of the top feed dog that horizontally synchronize with the bottom feed dog, to reliably feed the materials without damaging them. The feed mechanism smoothly feeds light-weight materials softly or feeds heavy-weight materials with an increased cloth-biting force.
  • The fulcrum of the top feed locus can be set at the bestsuited position according to the material or process.

The machine has been developed with the intention of providing an extended service life

  • The bottom and top feeds are equipped with separate differential feed micro-adjusting mechanisms. Various adjusting mechanisms to adjust the feed to ideally match the material being sewn are equipped as standard, such as the bottom feed dog inclinationadjusting mechanism and the external differential feed-increasing mechanism.
  • Comfortable operation is all but guaranteed, by a wider area around the needle entry, the adoption as standard of a microlifter feature that offers improved responsiveness to materials and provides the operator with upgraded operability, and by the reduction of operating noise and vibration, which has been achieved by designing an optimally balanced machine.

Further increased reliability
The introduction of a shield-structured needle bar mechanism and upper and lower needle bar bushings, contributes to increased durability and reliability. Additionally, the machine incorporates an improved upper looper unit as well as coming standard with a cartridge type oil filter and cooling fan, thereby ensuring enhanced reliability.

The needle thread heat remover and needle cooler are equipped as standard
To offer improved sewing capabilities as well as to prevent stitching misshapes, the machine is equipped as standard with the needle thread heat remover and needle cooler.

Devices intended for conventional JUKI machines are also interchangeable
Gauges and devices you have used with your existing JUKI machines are also interchangeable with no additional machining required. This eliminates both the waste of resources and unwanted extra costs.
