Description
The Merrow MB-4DFO 2.0 is an industrial flat overlock machine designed for base layer garments and technical textiles. It is the only machine able to sew all three variations of Merrow’s ActiveSeam stitch.
The ActiveSeam stitch replaces traditional flatlock seams: it is flat, comfortable and stretchable. It removes the raised seams that chafe the skin under technical clothing.
Manufactured in the United States, hand-assembled. Merrow has built overlock machines since 1838 and invented overlock stitching in 1881.
Description
The MB-4DFO 2.0 sews with two needles, which allows three different stitches with two or three threads. Stitch width adjusts from 3/32 to 5/32 inch (about 2.4 to 4 mm) according to material and application.
Merrow’s barrel cam architecture and curved needles give precision and consistency beyond conventional loop machines. Each machine is set up for the customer’s material and thread: tension, eccentrics and cutter position are adapted.
Merrow builds a custom machine at no extra cost, starting from the stitch sample supplied by the customer.
