Abstract
The complete, two-color, multiple keybutton array of a keyboard is molded by a two-shot injection molding method which uses a rotating, double female die means selectively cooperating with two male dies. The finished keybutton array is ejected to a carrier which then cooperates with a gathering fixture, which fixture is then movably adjusted to place the keybuttons in position for assembly to the keyboard.
