The button sewing machine is a special automatic sewing machine, which can sew buttons with regular shapes, such as nailing trademarks, labels, hats, etc., by using the "nail drop" technology.

The most commonly used staple is a disc-shaped two-hole or four-hole (also called 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 and so on. Users can request equipment suppliers to provide special accessories for the buckle machine according to their needs.
