Abstract
This disclosure depicts a novel edgebond system for implosion protecting a color television picture tube having a flangeless faceplate and a mating funnel. The edgebond system is illustrated as comprising, in its most general sense a high tensile strength metal scalloped frame which is cemented to and binds up a portion of the funnel and also the edge surface of the faceplate, i.e., the thickness dimension of the faceplate. The system assists in retaining in position the shards of a shattered faceplate and thereby provides for a relatively gradual buildup of pressure in the tube and provides for a maximum overlay of the funnel and a maximum volume of cement at the center of the sides of the funnel to provide greatest implosion protection at portions of the tube where greatest protection is needed.
