Abstract

PURPOSE:To obtain and also maintain uniform residual tension value by a wire band provided on the peripheral circumference of a cathode-ray tube wound with a thermosetting adhesive tape and also by forming a fitting seat with a part of the wire band. CONSTITUTION:The maximum portion of the peripheral circumference of the cathode-ray tube 1 is wound with one round of the thermosetting adhesive tape 8, and then the endless wire band 9 larger than the maximum portion of the peripheral circumference of the cathode-ray tube, whose one end is superposed on the other end and then calked, is positioned in relation to the cathode-ray tube 7. Then, the endless wire band 9 is electrically energized, the wire band 9 is clamped through the core metal of a banding device and rotated with the core metal at an optional position, and then between a position where a tension is to be applied along the cathode- ray tube 7 through the adhesive tape 8 and a portion turned by the core metal is twisted to form the fitting seat 11.
