The button stitching machine is a special automatic sewing machine, which can stitch buttons with regular shapes and perform operations with "stitching and dripping" sewing techniques, such as stitching trademarks, labels and caps. The most commonly used staple is a disc-shaped two-hole or four-hole (also known as flat button) button. By replacing the accessories of various special buttoning machines, one buttoning machine can sew buttons with handles, metal buttons, snap buttons, foot-binding buttons, wind buttons, etc. Users can ask equipment suppliers to provide special accessories for buttoning machines as required.
