ABSTRACT:
A rail for a curtain and the like suspension and drawing system comprises continuous drawn or extruded material of generally hollow or tubular shape whose cross section is such as to provide a pair of parallel longitudinal slots for guiding the oppositely running laps of a flat draw belt in an on-edge attitude so that its width is vertical, the rail being capable of flexure or bending in directions normal to the vertical plane of the belt to conform to a curved bay. The slots are separated by an integral web, and each has a longitudinal outwardly directed opening through which a member can project carrying at the inner end a belt clamp and at the other end a master glider running along a track parallel to the slots. The glider track, which may also serve to support free running gliders, may be formed by a surface which is an integral part of the rail adjacent the opening in the slot, for example, at least one longitudinal face edge of the opening.
