Photograph of the doughnut machine used to extrude Krispy Kreme doughnuts until the 1960s.

The Krispy Automatic Ring-King Junior was introduced by the Krispy Kreme Doughnut Corporation of Winston-Salem, N.C., in the 1950s. It was designed for making the company’s signature product—hot glazed doughnuts—in small retail operations around the United States and abroad. The Ring-King Junior could produce about 60 dozen doughnuts an hour, and was used until the late 1960s.
