Automated button closing machine
 A machine for automatically joining front and back parts of buttons employs a turntable with nests that are rotated through a series of stations at which the parts are placed in the nests in a desired orientation, joined, and checked for defects. Orientation of the parts is achieved by video imaging of a first part as it is randomly placed in a nest, and computer-controlled placement of the second part based on the ascertained position of the first part.
