The Advantage of the 70-D3B-2 CNP
The Merrow 70-D3B-2 CNP industrial sewing machine is designed to sew in harsh environments. It produces the same flat butted seam that has made the 70-D3B-2 the industry standard for end-to-end seaming, but has been chemically nickel plated (CNP) to allow for sewing on wet fabric. Chemically adhering the nickel to the machine offers the utmost protection from corrosion, and like all Merrow machines the 70-D3B-2 CNP is hand assembled with high quality steel parts, ensuring a perfect butted seam even after years of use.

The Merrow 18E sews a 3/8" - 1/2" flat crochet stitch on blanket and garment edges. It runs at speeds up to 1400 SPM, yet produces a stitch that rivals any sewn by hand in craftsmanship and uniformity. The 18E is a single needle, single thread machine that sews at a standard 4 SPI, but can be adjusted to sew at a remarkable 10 SPI.
WHY it's better

The Merrow MG-3U
The Advantage of the MG-3U
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.
WHY it's better
The Merrow Edge is the standard bearer for emblem edging on smaller patches, badges, and insignias. Noticeable for its finish and regularity, the Merrow Emblem Edge is a distinctive mark of quality that can only be made by the Merrow MG-3U.
HOW it's better

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.
