Merrow ActiveSeam™ Flat Overlock Machine

The Merrow MB-4DFO 2.0 is a revolutionary ActiveSeam™ flat overlock machine, designed to deliver a premium alternative to traditional flatlock, overlock, and interlock stitches. Developed exclusively by Merrow, the MB-4DFO 2 Series is engineered for advanced performance in activewear, sportswear, and technical apparel production.

As part of the 2 Series platform (2.1, 2.2, 2.3, 2.4), the MB-4DFO 2.0 is a two or three-thread industrial serger that creates Merrow’s patented ActiveSeam® stitch—a flat, stretchy, and highly durable seam that moves with the body, offering both aesthetic appeal and unmatched comfort.
