At its core, the single needle lockstitch machine operates using a straightforward mechanism. It consists of two threads—a top thread and a bottom thread, typically wound on a bobbin.

When the needle pierces the fabric, it creates a loop that intertwines with the bottom thread. This action produces a tight, secure stitch, which is the hallmark of lockstitch technology.
