Universal Alignment Adapter

Abstract

In a shadow mask tensioning method and apparatus, a shadow mask supported by a support frame is positioned between a shadow mask frame and a set of actuators with a portion of the shadow mask extending across a gap between the support frame and the shadow mask frame. Under the control of a programmed controller, the set of actuators is caused to simultaneously displace numerous, spaced locations of the portion of the shadow mask into the gap to align alignment apertures of the shadow mask to predetermined positons in fields of view of cameras positioned to observe the alignment apertures. The shadow mask is then affixed to the shadow mask frame.
