The zigzag stitch is a versatile sewing technique that creates a stitch resembling a zigzag pattern. This functionality is vital for tasks that require stretching, such as sewing knit fabrics, as the zigzag stitch allows fabric to move without breaking the seams. Additionally, this stitch is perfect for finishing edges, preventing fraying, and adding decorative touches to sewing projects. Industrial zigzag sewing machines are built to handle heavy-duty materials, providing precision and durability that standard home machines may lack.

Heavy duty machines typically have higher maximum sewing speeds, around 1500 stitches per minute, versus 1000-1200 stitches per minute for standard machines. Again, this allows them to work through heavy fabrics more efficiently. However, heavy duty machines also tend to sew better at slower speeds, in the 500-800 stitch per minute range, for optimal control through thick seams. So they provide a wider speed range to suit the fabric.

An extra heavy-duty sewing machine is an expensive investment. Choose a reputable retailer that is an authorized dealer for your chosen brand. Ideally, the retailer will have all of the manuals and specs online - this will let you ensure that you are choosing the right-sized machine (see question 1). A good retailer should also carry replacement parts and accessories for your machine. Bonus points if they carry additional brands - tell you which ones will work for your particular model.
