The Advantage of the MG-3DW-7
The Merrow MG-3DW-7 is the best performing industrial overlock sewing machine for sweaters, fleece, and heavyweight wools. It sews a 1/4" stitch at high speed (5500 RPM) that won't pucker, curl, or pull back thread. It is a single needle, three-thread machine built on Merrow's proprietary cam driven architecture, which makes the machine as durable as the stitch is resilient.
WHY it's better
When it comes to tight, strong, uniform, and resilient seams, the MG-3DW-7 is unequalled. It is designed with simplicity in mind - simple to thread, simple to sew, and simple to service - taking the burden off the operator and placing it directly on the machine. And because it is a Merrow, you know that it will last a lifetime. This combination of seam quality and machine durability has made the MG-3DW-7 the sewing machine of choice for overseaming heavy materials for decades.
HOW it's better
The MG-3DW-7 sews a tight needle stitch using three threads, and its wide opening cutters accommodate thick seams, multiple layer inserts - even crossing elastic sections. It provides extra looper and needle throw which is a must when sewing heavier knits and wovens.
WHERE it's used
The MG-3DW-7 should be used anywhere that quality seaming is required - sweaters, blankets, sportswear, or outerwear are common applications.

Merrow Machine Advantages
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".
In 2010 Merrow Machines are engineered and built in Fall River, MA.
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.
VERSATILITY (for OVERLOCK SEWING):
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 sitch to accomodate more demanding fabrics
