A rim space (20) sealing device comprising a peripheral sealing ring of over-lapped shoe segments (36) attached to a floating cover within a storage tank (22). Spring loaded hanger-pushers (68) and horizontal springs (74) keep the peripheral sealing ring of shoe segments (36) pressed against the tank wall (22) and also keep the floating cover (24) centered within the tank (22). The space (20) between the peripheral seal- ing ring of shoe segments (36) and the floating cover (24) is covered by a flexible fabric (94) that prevents products loss. Vertical movement of the individual shoe segments (36) over each other is prevented by a series of circumferentially arranged rods (82). The over-lap of the shoe segments (36) is restricted by a series of bars (44) forming expansion-contraction spaces (48).
