Free arm的意思

"Free arm" is a term used in sewing and embroidery, particularly with reference to sewing machines. It refers to the ability to move the arm of the sewing machine freely without the fabric being trapped or restricted by the needle plate or throat plate. This allows for greater flexibility in sewing and embroidery projects, especially when working with sleeves, pant legs, or other areas where the fabric needs to be manipulated freely.

In some sewing machines, the free arm feature is a removable part that allows the operator to create a smaller, more accessible area for sewing cylindrical or tubular items. This is particularly useful for sewing cuffs, sleeves, pant legs, and other cylindrical parts where the fabric needs to be turned inside out.

The free arm feature is also beneficial for quilting, as it allows the operator to sew around corners and edges more easily. It provides a clear view of the sewing area and allows for better control of the fabric, resulting in a more precise and professional finish.

In summary, the "free arm" is a feature of sewing machines that facilitates the sewing of cylindrical or tubular items by providing a clear and unobstructed workspace for the fabric.
