The lever-activated mechanism makes it easy to engage higher stitch counts when needed, making the 70-Y3B-2 a powerful tool in textile finishing, technical fabric processing, and other heavy-duty industrial applications. Known for its flat, low-bulk seams and Merrow’s trusted engineering, this machine delivers unmatched reliability and seam strength.
