This specialized equipment creates seams with minimal bulk by joining fabric edges in a way that lays flat against the body. This is achieved through various mechanisms, including specific stitch formations like the coverstitch, and specialized presser feet that help to control the fabric during stitching. A common application is the construction of athletic wear or undergarments.
The reduced bulk and smooth finish offered by this technology enhance comfort significantly, eliminating chafing and irritation against the skin. Historically, achieving such flat seams was a labor-intensive process. The development of these machines represents a significant advancement in apparel manufacturing, increasing efficiency while also improving the quality and wearability of garments. This has led to their widespread adoption in the production of performance apparel, intimate apparel, and other clothing where comfort and a close fit are paramount.
