MB-4DFO
Three-Thread Infused Seam

The MB-4DFO is an advanced two-needle sewing machine that has been introduced to sew on today's technical activewear fabrics. Built on Merrow's unique cam driven architecture, the MB-4DFO sews a flat overlock seam that replaces conventional cover and flat stitching. At 5/32 in width, the seam is as attractive and functional, giving with the material along the long axis of the seam yet holding strong across the short axis.

The stitch is exceptionally flat and is nearly imperceptible when worn on base layer garments that rest next to skin. The MB-4DFO sews with two or three threads at 5500 RPM and can be adjusted at the factory to sew on all weights of fabric for technical activewear. For visual distinction and technical performance, the MB-4DFO is the next advancement in technical sewing.

ActiveSeam® Infused Three-Thread Seam

ActiveSeam's comfort and stretch characteristics compliment merino wool's reputation for soft feel and elegant appearance. The 3-thread Infused stitch has a narrow profile that adds detail and style to even the lightest merino knits and works well on 135g to 170g garments.

  • SPEED: 5500 RPM
  • STITCH WIDTH: 5/32"
  • MATERIAL: 135g Pure Merino Wool
