A method to make a display board (8) illuminated by light fibres (11), in which method a display board illustrating different figures is produced by arranging the illuminating ends of the light fibres into wanted spots onto the surface of the display board. Board perforation and feeding the light fibres (11) into holes (13) as well as cutting off the light fibres are carried out in successive steps using the same coordinate controlled punching and feeding device (4, 5, 6, 7).
