MO-6900J Series
Variable Top-feed, Overlock / Safety Stitch Machine for Extra Heavy-weight Materials
Product features
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.
