ABSTRACT:
An implosion-resistant cathode ray tube has an envelope with a flared portion sealed to a skirt portion joined to the viewing portion of a face plate member. A pair of substantially flat rimbands each has one or more bracket members affixed thereto and an adhesive applied to the inner surface thereof. The rimbands are positioned on the skirt portion rearward of the jointure of the viewing and skirt portions and formed to encircle and adhere to the skirt portion by a strap member applying a compression force to the rimbands.
The cathode ray tube is fabricated by selecting and positioning a pair of substantially flat rimbands in a jig for positioning brackets, welding the brackets to the rimbands, applying adhesive to the inner surface of the rimbands, placing the rimbands on the tube and encircling the rimbands with a strap member to form and compress the rimbands and adhere the adhesive to the skirt portion of the face plate member.
