Abstract
This disclosure depicts a novel edgebond system for implosion protecting a color television picture tube having a flangeless faceplate. The edgebond system is illustrated as comprising in its most general sense a high tensile strength metal contoured frame, preferably having a substantially constant depth around the faceplate, which is cemented to and binds up 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.
