Abstract
A louver for a louver blind curtain comprising two parts which can be moved in a telescope-like manner with respect to each other. By means of a rubber traction device, the louver parts are subjected to pre-tension in the direction toward the shortened position of the louver. The louver curtain comprises a multitude of louvers whose length can be automatically changed and which are guided at both ends on guide tracks. The connection between the louver and each guide track is achieved by a respective slider, where the slider is provided at one end of the louvers with a drive, to change the angular position of the louvers. In addition, those sliders which travel the longest distance during the opening and the closing of the curtain are provided with screwed spindle drives.
