<p>The display unit for wallpaper on sale has compartments for rollers. Each compartment has a frame with two vertical uprights (6) each supporting a top (8) and bottom (9) pulley. Two parallel endless belts (13) are situated on two vertical parallel planes. Horizontal spindles each support a roller and their ends are joined to the endless belts (13), which can be driven and stopped in any position. A mobile trolley (25) which runs along in front of the supports, has a mechanism for unrolling a length of wallpaper from a selected roller, and a meter to record the length of the unwound lengths. The trolley (25) has legs (26) on which are wheels running on rails. A cranks handle (33) on the table of the trolley (25) drives the unwinding mechanism.</p> |
