Abstract
Arrangement for making color-picture tubes screens consisting of a faceplate panel and an associated shadow mask by applying phosphor layers to the faceplate using photographic techniques, at which devices for applying, exposing, and developing photosensitive layers are provided. To reduce the handwork without obtaining an assembly-line-like automatic arrangement with interdependent devices, the devices for exposing the screen are united with devices for inserting the shadow mask into, and removing it from, the faceplate to form an automatically operating subarrangement which is independent of the remainder of the arrangement.
