Abstract: The display (12) comprises a band carrying a series of visual items of information and held taut between two rolls (5, 9) onto which it is rolled, the rolls being parallel to each other and rotatively mounted in a frame (1), and a synchronous driving mechanism (18) for the two rolls. The driving mechanism comprises a toothed belt or chain (21) driven by a motor (19) and cooperating with a first sprocket wheel (22) keyed on the first roll (5) and a second sprocket wheel (23) freely rotatable on the second roll (9) and connected to the latter by elastically yieldable means (25) for compensating for the tension of the band as a function of the variation in the diameter of the roll resulting from the rolling up of the band.
