JUKI MO-6904J-0F6-700 JEANS 3 THREAD TOP FEED OVERLOCK
Juki MO-6904J-0F6-700
Variable Top-feed, 1-Needle 3-Thread Overlock / Safety Stitch Machine for Extra Heavy-weight Materials
An advanced full-featured machine that is ideally suited to the sewing of extra heavy-weight materials.
The machine incorporates a mechanism and parts that are optimum for the sewing of extra heavy-weight materials, such as an extra high-lift type upper looper, tractor foot and coarse type feed dog.
It demonstrates an excellent performance ability in the sewing of various kinds of heavy-weight materials such as jeans, raised fabric materials, mats and carpets.
An advanced full-featured machine that is ideally suited to the sewing of extra heavy-weight materials
The MO-6900J Series comes with a newly-developed feed mechanism that moves the top and bottom feeds separately.
With its improved feeding capacity and stronger cloth-biting force, the feed mechanism prevents uneven material feed when sewing extra heavy-weight materials.
- The machine incorporates mechanisms that are both durable and reliable, such as the needle bar mechanism, utilyzing the upper and lower bushings, a cartridge type oil filter and cooling fan.
- The machine is equipped as standard with a micro-lifter that helps reduce operator fatigue. The micro-lifter is designed to achieve optimum balance, not only reducing noise and vibration but also ensuring comfortable operation.
- Needle thread heat remover and needle cooler prevent stitching troubles during times of high-speed sewing, thereby contributing to upgraded seam quality.
- The machine comes standard with various adjusting mechanisms, such as a micro-adjusting mechanism, all of which can be easily adjusted to enable the machine to perform sewing under the best-suited conditions for any kind of material.
