Abstract
Abstract A curtain-tape, for hanging a curtain and forming fan-pleats, comprises a tape adapted to be attached, more particularly sewn, along one edge of the curtain, and elements secured thereto at predetermined intervals or alternating intervals and adapted to be joined together to form fan-pleats. In order to make up the elements, slides, rollers or the like, known per se, are divided into individual slide- or roller-elements. Several such slide- or roller-elements are, in turn, adapted to be connected together, thus forming a fan-pleat, into a group of slide- or roller-elements.
