ABSTRACT:
A roller shutter arrangement, more especially for obliquely arranged roller shutter areas comprising a roller shutter element running in lateral guide rails and adapted to be wound and unwound on and from a take-up shaft arranged at one end of the roller shutter area. At least one elastic draw cable is provided engaging the free end part of the roller shutter element, and this draw cable is stretched on winding up the roller shutter element on the take-up shaft and on unwinding provides an elastic force aiding the unwinding operation. This means that automatic unwinding of the roller shutter element is possible in a simple and economic manner even if there is an insufficient or no action of gravity.
