A lock stitch is created by interlocking two threads—a top thread and a bobbin thread. The top thread is fed through the needle and forms a stitch on the front of the fabric. The bobbin thread, located in a lower compartment of the machine, loops up to meet the top thread, forming a secure stitch that is often used for a wide array of sewing applications. This type of stitch is characterized by its tightness and durability, making it suitable for sewing heavier materials such as denim and canvas, while also being gentle enough for lighter fabrics.

The evolution of sewing machine heads for FIBCs has seen the integration of cutting-edge technology. Digital controls and computer programming features allow manufacturers to optimize production processes, reduce waste, and enhance productivity. Automated functions enable higher output rates while maintaining quality, a crucial factor in today’s competitive manufacturing landscape.

Before you begin, it's essential to select the appropriate twin needle for your project. Twin needles come in various sizes and widths, from 1.6mm (2.0mm between needles) to 4.0mm (6.0mm between needles), and can have ballpoint or sharp points depending on the fabric type you are sewing. Ballpoint needles are best for stretch fabrics, while sharp needles work well with woven materials.
