What is a Long Upholstery Needle?

Besides edge finishing, overlockers can also perform various stitches, including flatlock and chain stitches. Flatlock stitching is especially beneficial for activewear, as it lies flat against the skin and reduces irritation, while chain stitching offers flexibility and strength, making it suitable for stretchable fabrics. Many modern overlockers also come with adjustable settings, allowing users to customize the stitch width, length, and tension to suit different fabric types and project needs.

At the heart of the Union Lockstitch is its unique mechanism, which utilizes two threads—one from the needle and the other from a bobbin underneath the sewing plate. This lockstitch design creates a strong, durable seam that is essential for various types of fabric, including heavy materials like denim and lightweight textiles like silk. The machine operates by interlocking these two threads through a series of movement cycles, ensuring that the stitches are evenly spaced and consistent in tension.

One of the key features of the single needle bag closer is its ease of use. Operators can quickly become proficient in handling the machine, allowing for a swift transition from setup to sealing. The machine typically comes equipped with adjustable speed controls, enabling operators to modify the sewing speed according to their needs. This flexibility is particularly beneficial in high-volume production environments where efficiency can significantly impact profitability.
