Window cover systems include window cover material in the form of pleated panels (15) or slats (52). The window cover material is suspended from a traverse track (21) and is traversed along the track (21) for opening and closing the window system. Arrangements for maintaining spacing and alignment of pleats or slats (52) are provided. The alignment maintaining arrangements include traverse tapes (20) which are substantially rigid in longitudinal and lateral directions in the plane of the tape (20). The arrangements also include attaching the window cover material to vertical edge members (122) and providing foldable spacer-members (130) between adjacent edge-members (122). In one arrangement, a box-pleated panel of window cover fabric (220) is suspended from a traverse track (110) on slide-members (236, 238). Other arrangements include combined, tape-supported vertical slat blinds and vertical pleated drapes in which the tapes (220B, 220T) are supported by sprockets, wheels or pulleys. |
