Abstract
A method and device for manufacturing a CRT enables four springs to be accurately welded to the apertured grill without disordering the relative position of the pin holes in each of the springs even if simultaneous welding is not carried out. The location of the pin hole is indexed in such a way that a space between the surface of the grill and the inner surface of the panel may always be kept constant at any location under a state in which the apertured grill is fixed to the panel. The spring is welded in advance to the spring holders of the lower lateral member and the right and left vertical members in such a way that the pin hole is positioned at the indexed location. The remaining one spring is positioned in such a way that the pin hole is positioned at the indexed location when the apertured grill is positioned to cause the relative positions of the pin holes of the welded three springs to coincide with the relative arrangement of the pins of the lower, right and left skirts of the panel. Then the spring is welded to the spring holder of the upper lateral member.
