Factory fixture frame for an in-process tension mask color cathode ray tube

For use in the manufacture of a color cathode ray tube having a flat faceplate and a tensed foil shadow mask, a reusable factory fixture frame for mounting an in-process shadow mask during photoexposure of an in-process faceplate in a lighthouse, said frame comprising generally rectangular frame means and quick-release mechanical mask-retaining means for temporarily and removably supporting an in-process shadow mask in tension out of the plane of said mask, and providing for quick cementless and weldless retention and release of said mask, said frame having first six-point indexing means on a first side for registration with complementary registration-affording means on an exposure lighthouse, and second six-point indexing means on a second side for registration with complementary registration-affording means on both said whereby said in-process mask can be precisely registered and reregistered with said lighthouse and said in-process faceplate for the photoexposure of said in-process faceplate while retaining said in-process mask in tension, and whereby said frame and said in-process mask can be registered with said mask tensing and clamping means.

For use in the manufacture of a color cathode ray tube having a flat faceplate and a tensed foil shadow mask, a reusable factory fixture frame for temporarily mounting and conveying an in-process shadow mask for processing by manufacturing machinery, said frame comprising a generally rectangular frame means having a first side and an opposed second side, at least one of said sides having at least first and second six-point indexing means azimuthally rotated with respect to each other for indexed mating with complementary six-point indexing means on said manufacturing machinery.

For use in the manufacture of a color cathode ray tube having a flat faceplate and a tensed foil shadow mask, a reusable factory fixture frame for temporarily mounting and conveying an in-process shadow mask for processing by manufacturing machinery, said frame comprising generally rectangular frame means having six-point indexing means on a first side for indexed mating first with complementary six-point indexing means located on means for mask tensing and clamping, and subsequently with indexing means located on a lighthouse, and six-point indexing means on a second, opposed side for indexed mating with complementary six-point indexing means on an in-process faceplate.

For use in the manufacture of a color cathode ray tube having a flat faceplate and a tensed foil shadow mask, a reusable factory fixture frame for mounting an in-process shadow mask, said frame comprising generally rectangular frame means and quick-release mechanical mask-retaining means for temporarily and removably supporting an in-process shadow mask in tension, said frame having two related sets of six-point indexing means, the first of said sets providing for transporting said frame into a gross position relative to an operation utilizing said mask, with the second of said sets providing for assuring absolute accuracy in positioning said frame during said operation utilizing said mask.
