coverstitch sewing machine
A coverstitch sewing machine is a specialized piece of equipment that creates professional-looking hems and decorative stitches on stretchy fabrics. This versatile machine combines the functionality of both a serger and a standard sewing machine, featuring multiple needles and a looper system that works in tandem to create durable, stretchy seams. The machine typically uses 2-3 needles simultaneously to produce parallel rows of stitching on the top side of the fabric, while creating a looped, chain-like pattern underneath. This unique construction allows for maximum stretch capability while maintaining strength. Modern coverstitch machines come equipped with differential feed systems that prevent fabric puckering and stretching during sewing, automatic tension adjustment features, and various stitch width options. They excel at creating professional-looking hems on t-shirts, activewear, swimwear, and other knit garments. The machine can also handle decorative techniques such as flat-locked seams, binding attachments, and chain stitching, making it an invaluable tool for both home sewists and professional garment makers.
