General

The MB-4DFO is a NEW sewing machine designed by Merrow to produce ActiveSeam™. It is a two or three- thread premier industrial serger that sews three versions of the Merrow ActiveSeam. ActiveSeam is a NEW flat overlock stitch that provides an ALTERNATIVE TO FLATLOCK, INTERLOCK AND OVERLOCK STITCHING on sewn garments.The MB-4DFO sews all three variations of the ActiveSeam™ stitch. It was specifically developed to sew on base layer garments and the ActiveSeam™ family of stitches are flat, comfortable, and stretchable stitches that replace traditional flatlock seams. The MB-4DFO stitch width can be varied from 3/32" to 5/32" according to material properties and/or application requirements and is custom configured to sew specifically using customers' unique material and thread. Tension settings, eccentrics, and cutter placement are all adjusted to ensure that the customer receives a unique version of the ActiveSeam™ that is specific to their garment and application.The NEW MB-4DFO utilizes Merrow's unique barrel cam architecture and curved needles to sew more precisely and consistently than other sewing machines. Because the MB-4DFO sews with two needles, it has the versatility to sew three different stitches and with either two or three threads. The MB-4DFO is hand-built in the USA and all parts are integrally designed to ensure both stitch superiority and machine durability.
