Leather sewing machine

One of the primary functions of an overlocker is to finish raw edges of fabric. This is particularly useful for knit fabrics, which tend to stretch and curl. Overlocking edges with a serger provides a professional finish that is both durable and visually appealing. The machine utilizes multiple threads to create a strong seam, making it ideal for garments that require flexibility, such as t-shirts, leggings, and activewear.

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.

Heavy duty sewing machine motors are characterized by their high torque and efficiency. Unlike standard sewing machine motors, which may struggle with thicker materials, heavy duty motors provide the necessary power to execute strong stitching with ease. Typically, these motors range from 1/3 to 1 horsepower, and in some cases, even higher, allowing for faster sewing speeds and greater force.

What is Lock Stitch?

2. Durable Build Look for machines with a metal frame rather than plastic. A sturdy build provides stability and minimizes vibrations while sewing, leading to more accurate stitching.

One challenge faced with handheld sewing machines is their power and tension settings. Unlike traditional sewing machines, which typically provide adjustable tension, some handheld models may not offer the same versatility. Thus, it's crucial to practice and understand how your specific model handles thick fabrics. Testing on scrap pieces can help gauge how much pressure to apply and what settings yield the best stitch quality.

The zigzag stitch is characterized by its zigzag pattern, which allows for flexibility in fabric handling compared to straight stitches. This stitch can stretch, making it ideal for use on knit fabrics, elastic materials, and projects that require a degree of stretch. The zigzag stitch can also be used for decorative purposes, adding visual interest to garments and textiles.
