An arrangement for retracting and extending a roller blind web has a shaft (8) rotatably mounted in a cassette (6). A first longitudinal edge (10) of the roller blind (4) is mounted on the shaft (8) and can wind around the shaft (8). An end strip (14) is movable relative to the cassette (6) and has a housing (20) to which the second longitudinal edge (12) of the web (4) is connected. First and second gearwheels (30) with different diameters are in the housing (20) of the end strip (14) and can rotate about a common shaft (34). First and second telescopic arms (22, 24) are in the housing (20) and have first and second racks (26, 28) that engage the first and second gearwheels (30, 32). Thus, the telescopic arms (22, 24) can move simultaneously relative to the housing (20) by different distances in opposite directions.
