<p>The roller blind has two guide rails (25, 26) running parallel to each other on two sides of a clamped blind web (22), and two cylindrical piping units (49, 51) running in a guiding chamber (29) of the guide rails. The guide rails are connected with a tensile bar (23) in a tight manner or in a compression proof manner, where each of the guide rails forms an inlet edge (45) at an end, which is adjacent to a winding shaft (38). An intermediate space of the guide rails is smaller than the breadth of the blind web.</p> |
