The Factory Refurbished M-3U
In 2008 Merrow began selling a factory refurbished model of its industry standard M-3U. These Sewing Machines are hand built on Merrow's assembly line in Fall River,MA and include less than 6% reconditioned parts. They are effectively new sewing machines: tested and sewn off after assembly with the same rigorous standards Merrow uses for all sewing machines built in Fall River, MA. The Refurbished M-3U carries the same warranty as all new machines. It is provided by Merrow: 'to reduce the overall cost of owning and operating Merrow Sewing Machines without compromising performance'. Please call Merrow if you have any questions or concerns about the refurbished line of machines. NEEDED FOR OPERATION:
K-Leg Table with light
A standard sewing table modified for the Merrow M-3U. It comes with a storage drawer, a sewing light, and treadle. Speed Adjustable Servo Motor
Merrow has been pairing the Refurbished M-3U with this servo motor for more than two years. It allows the operator to easily run the machine at slow speeds (which can be very helpful when learning how to edge emblems). The Motor is warrantied by Merrow for one year. Please call Merrow directly with questions about the motor. Merrowing Thread
Three spools are included, the color can be specified when you place your order. These are the same thread cones that Merrow will sew the M-3U off with before shipping. They are a 1LB Merrowing Thread cone, 1000 yards of a Merrow Tex 40, and 1000 yards of a Merrow Tex 70.

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
