Most machine operators don’t realize they’re working with the 700K Series—especially models like the 747K, 757K, or 767K. Instead, they search for things like “industrial overlock thread cutter not working” or “4-thread machine feeding issue.” To simplify the process, we’ve grouped all essential 700K Series-747K/757K/767K spare parts so you don’t need to know your model name—just your problem.

What Are 700K Series Machines?

The 747K, 757K, and 767K models are part of the 700K Series, a collection of advanced industrial overlock sewing machines used for high-speed seam finishing and edge joining in garments. These machines offer durability and precision for factories handling knitwear, casuals, and stretchable fabrics.

They typically handle 3-thread, 4-thread, or 5-thread configurations, depending on the model. As with all industrial machines, their performance can decline due to heavy use. Replacing key parts often restores stitching consistency.

Signs You Need New Overlock Parts

You may need replacements if your machine:

• Stops trimming thread cleanly

• Feeds fabric unevenly or jams during use

• Starts skipping stitches

• Becomes noisy or unstable while running

By replacing worn components with the correct 700K Series-747K/757K/767K spare parts, you can quickly restore its original output.
