The needle bar is an essential part of a zipper machine that holds the needle in place. The needle bar has a hole where you can insert the needle clamp screw, which in turn holds the needle firmly in place. The needle bar moves up and down to help the needle penetrate the fabric, and it is the part that helps stitch the zipper into the fabric.

2. The Feed Dog

The feed dog is the part of the zipper machine that holds and moves the fabric underneath the needle. It has a toothed surface that grips the fabric and then moves it forward or backward, depending on the stitch being used. In other words, the feed dog ensures that the fabric moves in sync with the needle, allowing it to stitch the zipper as required.

3. The Bobbin Case

The bobbin case is the part of the zipper machine that holds the bobbin. The bobbin case is installed on the hook base and is kept in place by a retaining ring. The bobbin case is essential because it applies tension to the bobbin thread, which in turn affects the overall stitch quality of the zipper being stitched.

The hook base is the part of the zipper machine where the bobbin case is installed. It is a critical part of the machine because it ensures that the bobbin is placed in the right position. Moreover, hook base also has teeth which meet the needle and ensures the formation of the stitch.

5. The Tension Assembly

The tension assembly is responsible for regulating the tension of the thread. It is the part of the zipper machine that is responsible for the strength and smoothness of the stitch. The tension assembly usually consists of two discs that are held together with a spring.

The knee lifter is a mechanical part of the zipper machine that helps the operator lift the presser foot without having to use their hands. The knee lifter is attached to the bottom right-hand corner of the machine head and is operated by the movement of the operator’s knee. It allows the operator to move the fabric smoothly without any hindrance, making sewing faster, easier and more efficient.

7. The Puller

The puller is an essential part of the zipper machine that grips the two sides of the zipper when they're being stitched to ensure that they don’t move out of position. The puller is also responsible for controlling the tension of the zipper teeth, which helps to ensure smooth operation and proper alignment of the teeth.
