发明名称 A method of manufacturing a metal button, a button formed by the method, and an article incorporating such a button.
摘要 <p>A metal button is disclosed comprising a button part 1 and a rivet part 6 both formed by cold forming respective pieces cut from a body of raw material. The button part has monolithic body providing a shank portion formed with a cavity 2 to receive the stem of the rivet part and with an enlarged head. In use, the stem of the rivet part 6 is inserted, from one side of a piece of cloth or the like, through a hole in the latter, into the cavity in the body of the button part and is pressed into this cavity to deform the rivet stem and increase the diameter thereof to fit tightly within the cavity in the button part. The button parts and rivet parts of a plurality of such buttons are formed by cold forming respective blanks cut, without scrap being formed, from a body of raw material such as a length of aluminium rod or wire. The simple unitary form of the rivet parts and button parts, and the lack of scrap, makes for economic manufacture.</p>
