ABSTRACT:
An implosion band for a cathode ray tube has a plurality of raised tabs distributed about the periphery of the rearward edge of the band to accommodate attachment of additional tube components such as degaussing coils. The tabs are formed by: punching narrow slots in a strip of band material, near a longitudinal edge of the strip; forming the strip into a hoop by butt welding the ends of the strip; and stretching the hoop into a rectangular band while at the same time displacing outwardly the band material between the slot and the edge of the band to form the tabs.
