ABSTRACT:
Hold members are used for abutting a shadow mask on the pins in the rim portion of the faceplate of a color picture tube. These hold members are of a two-part design and connected to one another with the aid of means permitting a transverse movement in relation to the axis of symmetry of the color picture tube. These means may consist either of a swivel joint or of a straight line motion device. During the first insertion of the shadow mask into the faceplate, any possible tolerances of the pins can be compensated for because the possible transverse movement of the hold members. The spacing between the shadow mask and the phosphor screen is not affected.
