Abstract
Disclosed are a method for manufacturing a frame for a Braun tube and a base material used therefor. The base material has a rectangular plate-shaped configuration obtained by machining a metal plate-shaped strap. The base material possesses an extended guide opening defined at a center portion thereof, the extended guide opening having a shape which is similar to the configuration of the base material and a dimension which is smaller than the base material. The base material further possesses a plurality of extended rupture-preventing grooves each defined at a corner portion of the extended guide opening to be communicated therewith, the extended rupture-preventing grooves having a diameter which is smaller than that of the extended guide opening. The strap has a pair of deformation-preventing notches formed on both side edge surfaces thereof, respectively, at a boundary region between two adjacent base materials, each notch having a bottom portion which extends parallel to the edge surface of the strap.
