A compound feed sewing machine is distinct due to its ability to feed the material from multiple sources—primarily the needle and the feed dog. This dual feeding mechanism helps to maintain an even tension on the fabric, ensuring that layers of varying thickness can be sewn together without puckering or shifting. The combination of the needle feed, presser foot, and feed dog working in unison allows for precise control over the sewing process, enabling seamless stitching even on difficult materials.

Another factor to consider when choosing upholstery machine needles is the type of stitching you will be doing. Different needles are designed for specific types of stitches, such as straight stitching, zigzag stitching, or decorative stitching. By selecting the appropriate needle for the type of stitching you will be doing, you can achieve professional-looking results with clean and precise lines.

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.

Additionally, these machines often come with multi-needle capabilities. This feature allows for the use of different thread colors and types without the need for constant rethreading, significantly reducing production time. High-speed operation is another hallmark of industrial zig zag machines, with some capable of producing thousands of stitches per minute, which drastically increases output.
