Roller with tensioning device and multi-pane isolating glass element with such a roller

摘要

The roller blind has a stretching device for stretching a roller blind fabric i.e. roller blind foil (4), over a glass surface i.e. pane (3). The stretching device has a pull rope (9) for loading the roller blind fabric with a tractive force that is directed opposite to a rolling direction (31), where the tractive force is included over a constant length of the pull rope and conducted over a loose roller (19). The loose roller is clamped by a tension spring (21), where the loose roller is guided parallel to a rolling shaft (6). The foil is made of the plastic material or metal.
