The Merrow MG-3U is a 3-thread industrial sewing machine that is meant for putting a decorative edge on emblems and patches. It makes a 1/8" to 3/16" stitch at a standard rate of 28 SPI (though this can be decreased or increased to 20 or 40 SPI respectively), yet even while running at 5500 RPM still operates under 90 dbA. The MG-3U carries a 10 year warranty, though it is expected to run for years after that with routine care.


Since 1838 Merrow has manufactured the world's best overlock sewing machines. A Merrow Machine is built to sew a more precise stitch and operate longer than any other competitive sewing machine in its class. Merrow Machines are engineered and manufactured more carefully, designed to last decades, and supported with a network of 156 agents in 65 countries. The Merrow Sewing Machine is The Most PRECISE and TOUGHEST sewing machine manufactured in the world

Overlock stitching was invented by the Merrow Machine Company in 1881. Merrow's original three-thread overedge sewing machine is the forerunner of contemporary overlocking machines. Over time, the Merrow Machine Company pioneered the design of new machines to create a variety of overlock stitches, such as two, and four-thread sergers, the one-thread butted seam, and the cutterless emblem edger. Today Two- and three-thread formations are also known as "merrowing".

    The MG-3U uses lightweight moving parts and needle bearings that are manufactured to extremely high tolerances, permitting the fast and smooth starts and stops inherent in intermittent operations like emblem edging. As a result, sewing edges on an MG-3U assures a uniformly finished, unmatched stitch.

  • Where It's Used

    The MG-3U is a versatile industrial machine that will satisfy the needs of the local emblem shop to the factory producing thousands of patches per day.




Additional Information

  • Quality of Materials

Our parts and machines are handcrafted and handbuilt


  • Cams NOT pistons -- Proprietary Cam Technology - Different from all other Sewing Machines

We're the only manufacturer in the world building Cam-driven sewing machines that stand up to heavy use. Merrow's Cam-driven machines produces a superior quality stitch. Using sophisticated 5-axis computerized milling machines, we've succeeded in developing proprietary high-technology components offering faster, quieter, operation and remarkable durability.


  • Merrow Cams are Machined to Exacting Dimensions

Tolerances are held to .001: the tightest in the industry. They have been designed to operate continuously between 2200 and 5500 RPM. Merrow Cams allow a Merrow Machine to create a perfect stitch while ensuring that the sewing machine will last a lifetime.


  • Special consideration should be paid to the intricacies of Merrow's Cam Technology

The Cam groove width and the final surface finish of the Cam groove are created with proprietary manufacturing technology that allows all sides of Merrow's Cam to have an equal, highly polished and uniform steel surface, this results in an approximate coefficient of friction, when lubricated, of .06 or lower.


Cam gear teeth are cut to a unique specifications with the sides of each tooth shaved to create a proprietary profile. This reduces heat when running.


Hardness and metallurgy of the Cams are continuously modified, improving the durability of the Cam. The Benchmark for the durability of a Merrow Cam in continuous operation is more than 30 years of operation without failure.

Sew thousands of different Material Types. Woven Fabric, Knit Fabric, Terry Towel, Denim, Technical Textiles AND Nonwovens. While the machines sew exceptionally on mid-weight woven fabrics, it performs well on a huge number of materials from vulcanized rubber to fiberglass to insulation.

With more than 645 different needle plates and feed dogs, we can modify the stich to accommodate more demanding fabrics.
