ABSTRACT:
There is disclosed a method for arranging a plurality of line filaments above the grid electrode supported on the base plate of a conventional fluorescent displaying tube. The inventive method employs a temporary mounting plate for temporarily supporting the filaments with tension until they are completely arranged above the grid electrode. The mounting plate comprises a plurality of cutting-off lines and a pair of weld portions at opposite ends thereof. The arrangement of the filaments accomplished, the temporary mounting plate is cut along the cutting-off lines so as to remove all the other portions except the weld portions.
