The invention means the improvement and the cheaper such facilities.

A band is tensioned around the flange or flange portion of the image base of a cathode ray tube. There is an adhesive strip between the strap and the cathode ray tube. The part to be viewed on the ball is perpendicular to the standard tube type in the Dioke, so that, in cooperation with the tensioning strap, it forms a twisted oohut against bursting.

In the whole of FIGS. 2 and 3, a strip 40 and a tensioning bed 42 are placed on the band * or flaneoate part 26 of the image disk 16. The bands are applied after the ring is evacuated.

It is necessary to make it easier to remove the screen from the mold. By arranging the surface of the flange 26 _/ in a substantially oenkreoht on a plane, which lies eenkreoht sur Lusachtic outer drilling, the tensioning band 42 can be applied to the sleeve without the risk of being diverted from the image 16. The resulting elasticity on the image disk 16 acts vertically on the surface of the lae and also increases the strength of the idea 24 and its ideratandaftuti ^ koit against high utilities. The greater thickness of the cathode tubes than that of the cathode tubes contributes to the increase in the efficiency of the cithode tube against smaller impacts.
