Abstract
A scrolling sign apparatus is disclosed. The apparatus includes a web having a number of signs connected in a loop. The web includes a bead along each longitudinal edge thereof. The apparatus includes a housing which has a window for displaying the signs. The web is wound on a number of rollers located in the housing which advance the web through the window. Each roller has two circumferential grooves located near the ends of the roller. The grooves engage the beads along the edges of the web.
