The needle's primary function is to form the stitch while sewing the cloth. The needle is inserted into the needle bar, which is secured by a small screw.
What holds the needle in the needle bar?
Are you familiar with the term "needle bar clamp"? The part of the needle bar that holds the sewing machine needle in place is called a needle bar clamp.
Where is the needle bar on a sewing machine?
The long cylinder that holds your needle is known as the needle bar. This is the first check and adjustment made before anything else, assuming the needle is properly seated in it (not backwards, slightly rotated, and/or not fully inserted).
Why does my needle keep hitting the plate?
If the needle plate and presser foot are not properly aligned, your needle may break. Because of the misalignment of these parts, your needle will have a tendency to hit one of these two parts. Even if you use the correct needle plate and presser foot, incorrect needle alignment can cause the needle to break.
Don’t over-tighten the needle bar clamp screw, especially when there isn’t a needle in the clamp.
