ABSTRACT:
A method and apparatus for substantially automatically joining front and back parts of buttons employs a turntable with retaining means that are rotated through a series of stations at which the parts are placed in the retaining means in a desired orientation, joined, and checked for defects. A human operator places button front parts at a first station, and the remaining stations carry out the assembly and quality control steps automatically. Placement at the first station determines the alignment and orientation of the two buttons.
