<p>The device (10) has a flat stretchable covering section (12) e.g. rolling section, rollable on a pivotably mounted winding shaft. A connecting rod (16) is arranged in the section, and is positively driven with an end section in guide rails (18, 20). The rod is coupled with a variable speed drive (34) i.e. gear motor. Drivers (26, 28) are coupled at the speed drive by a flexible and translationally movable bowden cable (38) e.g. wire rope. An elongation adjusting device (80) compensates operationally occurring elongation of the bowden cable.</p> |
