A vertical window covering system which utilizes an area of prepleated drapery fabric having permanently set pleats of a nature such that the fabric behaves like a tension spring tending to bias pleats toward the foled state or a vertical blind with taped or string ladders. The drape is hung from a traverse track adapted to be mounted in a horizontal orientation. A plurality of track mounting arrangements are provided for mounting a plurality of spaced pleats of the fabric intermediate left and right edge pleats thereof for bidirectional traverse relative to the traverse track. First and second drape edge carrier components are mounted to the traverse track with at least one of the carrier arrangements adapted for bidirectional traverse on the track. Drape edge stabilizer arrangements are mounted on each of the carrier arrangements for holding the edge pleats in a substantially true vertical orientation when the drapery fabric is traversed to an open pleat condition, i.e. the drape is closed over whatever structure it is covering. The intermediate pleats are stabilized in true vertical position by thin metal or plastic slats mounted to the intermediate pleats and carried on the pleat hanging arrangement mounting the drape to the traverse track. Preferably a traverse alignment arrangement using tensioned guide cords extending through apertures in each pleat gives pleat alignment during drape traverse.

In a vertical window covering system, a window covering material portion having a plurality of sections disposed in a generally vertical orientation, said portion being adaptable to being traversed between open and closed conditions and having an inherent distortion characteristic causing non-vertical hanging of left and right edge portions thereof in an open or partially open condition, a traverse track adapted to be mounted in a horizontal orientation; a plurality of track mounting means for mounting a plurality of sections of said window covering material intermediate said left and right edge portions thereof for bidirectional traverse relative to said traverse track; first and second edge carrier means mounted to said traverse track with at least one of said carrier means adapted for bidirectional traverse on said track; and edge stabilizer means mounted on each of said carrier means for holding said edge portions of said window covering material in a substantially straight vertical orientation when said material is traversed toward an open condition, including a stabilizer rod means mounted to said carrier means in an accurate vertical orientation and with a degree of rigidity sufficient to overcome said inherent distortion characteristic, said stabilizer rod means extending at least substantially the entire length of an associated one of said edge portions of said window covering material and being secured thereto at least at a plurality of locations throughout said length; wherein said window covering material portion includes a plurality of vertical material portions which move together as said material is traversed toward a closed condition and has the further inherent distortion characteristic operating during traversing toward said closed condition tending to cause said vertical material portions to become misaligned in a direction perpendicular to the general plane of traverse, and further comprising traverse alignment means for maintaining the alignment of said vertical material portions during said traverse toward said closed condition, said traverse alignment means including guide apertures formed in said vertical material portions at a prearranged position near a bottom edge thereof, guide cord means extending through said guide apertures and being fastened to one of said stabilizer rod means, and tensioning means operatively mounted to the other of said stabilizer rod means for maintaining said guide cord in substantial tension throughout the traverse of said material portion between said open and closed conditions.
