Abstract
An improved guide means suitable for use in a scrolling sign having an internal frame work and a sign face with a window in which indicia may appear. A web containing serial indicia is wound on web rolls. The web extends along a path between the web rolls and across the window for selectively displaying indicia on the window as the web is unwound and rewound on the rolls by a motor. The guide means includes a pair of plate-like guide members lying normal to the path of the web and spaced along the path. The guide members receive the web, at least along their edges so that the web extends between the guide members and across the window in the sign face and may contain baffles to eliminate light leaks. The guide members may be formed of translucent or transparent material to avoid shadows on the sign face. A brace member and adjustment bar may extend between the guide members. The guide members are fastened to plates lying at either end of the guide members having mounts for mounting the plates to the frame work of the sign. The web rolls may also be mounted in the plates so that the guide members, web rolls and plates form a module that can be installed in, and removed from, the sign as a unit.
