Big bag sewing machine

A coverstitch machine is designed primarily for hemming and finishing the edges of knit and stretchy fabrics. It produces a distinctive double-stitch on the front side and a serged finish on the back, effectively combining a professional look with durability. This type of machine is exceptionally beneficial for creating garments that require flexibility, such as T-shirts, leggings, and activewear. The coverstitch allows for easy movement of fabric without compromising the integrity of the stitches, rendering garments that are comfortable to wear.

A specialized zigzag presser foot typically features a wide groove at the bottom. This groove allows the needle to move freely from side to side without obstruction when creating the zigzag pattern. Additionally, many zigzag presser feet have markings that guide seam allowances, making it easier for users to achieve precise stitching.

At its core, the zig zag stitch machine combines the basic features of traditional sewing machines with the added functionality of creating a zig zag pattern. This unique stitch is formed by the machine's needle moving side to side while also stitching forward, allowing seamstresses to produce a variety of stitch widths and lengths. The adjustable settings on a zig zag stitch machine allow for customization, making it suitable for different types of fabric and sewing projects.

Heavy duty bag making machines are essential equipment in the packaging industry, capable of producing a wide range of bags that can carry heavy loads. These machines are designed to handle thick, tough materials such as plastic, paper, and woven polypropylene to create durable bags that can withstand rough handling and harsh environments.
