Abstract (en)
[origin: WO9845646A1] The present invention relates to a method of producing a combined anti-dazzle screen and a reflector (3) for a long fluorescent tube fitting (1), including lateral reflectors (5) and ribs (6), which connect the reflectors to each other and which ribs are wedge-shaped in cross section, with the wedge point (19) turned away from the source of light of the fitting and are fastened with their ends (7) in recesses (8) in said lateral reflectors (5) and which are bent from plane blanks made of metal and/or a plastic material. In accordance with the invention a completely punched rib blank (6) is, within the area for the rib point (19) to be made and on the exterior side (18) of the rib to be made, provided with a through material weakening (17), preferably made through embossing, subsequent to which the blank sides (14, 16) on each side of the weakening (17) are brought towards each other with said weakening as a swinging or folding centrum, until the blank sides (14, 16) bear on each other within the area of the rib point (19), obtained in this way, with an intact bridge (20) between the blank sides. The invention relates also to a cross-directed rib (6), produced according to the described method.
