The Advantage of the 70-Y3B-2

The Merrow 70-Y3B-2 industrial sewing machine from Merrow is the only sewing machine for butted seaming with a STITCH MULTIPLIER built into the sewing head. The machine sews a 5/8Ē stitch. The stitch count can be doubled while the operator is sewing and is effective for processing loose weaves to higher densities fabrics.

The Stitch Multiplier is a lever on the front of the machine that can be pressed to double the number of stitches sewn.



WHY it's better

The 70-Y3B-2 is the only butted seam sewing machine that has a STITCH MULTIPLIER built into the sewing head. Wide seams of joined fabric are weak at the edges (the selvages) and the 70-Y3B-2 addresses this by DOUBLING THE STITCH COUNT on demand to add strength to seams - when and where itís needed. To double the stitch count, the operator simply presses the 70-Y3B-2ís STITCH MULTIPLIER LEVER while material is being sewn. view the video


HOW it's better

The 70-Y3B-2 uses a NON-DIFFERENTIAL FEED ECCENTRIC which allows the stitch count to be doubled even though the material being sewn is fed through the machine at a uniform speed. To activate the feed eccentric, the operator simply presses the STITCH MULTIPLYING LEVER located in front of the work plate.


WHERE it's used

The 70-Y3B-2 is ideal for applications where swaths of WIDE FABRIC are being joined. Wide can mean weak AT THE SELVAGES, but not when the 70-Y3B-2 is used. The same goes for processing LOOSE WEAVES or HIGHER DENSITY FABRICS. In fact, the 70-Y3B-2 should be used for any application that requires that strength be added to a seam on demand.



The 70-Y3B-2 is one of more than 350 variations of the Merrow 70-D3B-2

Merrow Machine Advantages

HERITAGE

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.

DURABILITY:

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:
  1. 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.
  2. 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.
  3. 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 CONTINUOUS PROCESSING):

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.

the 5/8" stitch width
After years of testing we've determined that a 5/8" stitch is the most effective for joining materials at speed. Wider than the average sewing machine stitch by about double,the 70/72 Class stitch matches a substantial width with high speed sewing. The result is a fast process that is exceptionally versatile.

Flexibility
With more than 75 different needle plates and feed dogs, we can modify that 5/8" sitch to accomodate more demanding fabrics

Better than Glueing or Tacking
The 5/8" stitch is removable (unless you want to use the LS model), simple and inexpensive to apply
