The belt to be stored is entrained between a set of rollers (11) on a fixed frame (10) and a set of rollers (13) on a movable frame (12). Separation of the frames increases the amount of belt stored as lengths (31, 32 etc.) extending between pairs of rollers (24-25, 26-27, 28-29 etc.). The sets of rollers (11 and 13) are arranged at an acute angle to the direction of separation to minimize the height of the assembly. …<??>In modified assemblies the inclined sets of rollers form a V-shape, with two groups of rollers inclined at acute angles above and below the horizontal, or a Z-formation. |
