Abstract (en)
[origin: EP0451528A1] The invention relates to a device for displaying announcements, in particular prices in digital form, comprising two winding rollers (3, 4) arranged parallel to one another for a display belt (5), and at least one drive motor (8). In order to ensure that both winding rollers (3, 4) run synchronously with one another and hence that the display belt (5) is constantly tensioned, a drive motor (8) is assigned to each winding roller (3, 4) and the drive motor (8) winding up the display belt (5) onto the one winding roller (3) is operated at a higher speed than the drive motor (8') unwinding the display belt (5) from the other winding roller (4). <IMAGE>
