Abstract: A tensioning device for use with an endless traverse which is longitudinally adjustable in both directions responsive to a rotational drive. The rotational drive includes two driving gears which are each selectively coupled with a drive shaft so that when one of the driving gears is positively driven, the other driving gear is permitted to rotate freely. The traverse changes from one driving gear to the other by passing from between a pair of overlying side walls and over a flange. Elongation resulting from strain of the traverse is continuously led out of the system so that blocking or braking of the traverse is avoided. The tensioning device is especially suitable for the operation of strip curtains or conventional curtains, as well as for curtain systems with large and heavy traverses.

Abstract: An elongated strip of stiff material formed with a series of transverse folds across the strip. At least two adjacent panels between folds turn inwardly to form pleats between spaced control panels. Each control panel has at least two parallel string encasement means aligned with encasement means on other control panels. A control string through the control panels and extending beyond the strip draws all of the control panels into close proximity with adjacent control panels all in the same plane. Between adjacent control panels pleat panels are folded inwardly to form pleats which are then tacked to the control panels. All of the pleats are formed simultaneously and automatically. The top of the drapery material is folded over the strip and tacked together to form a sleeve over the strip. Each panel may be tacked to the drapery material. The strip may be extruded of synthetic material and the folds formed by stamping living hinges at desired intervals in the strip.

Abstract: A device is provided for applying tensile forces to a flexible cord to draw the cord toward the device. The device has a base, a drive wheel rotatably mounted to the base and a pair of traction rollers within the plane of the drive wheel. The cord circumferentially engages the drive wheel and is urged against it in secure frictional engagement by the rollers. In a preferred embodiment, the rollers are carried at opposite ends of a connector link which is mounted for pivotal movement relative to the base. The cord extends around the drive wheel as a loop and two leads of the loop are guided outwardly from the wheel by the rollers. The rollers and the connecting link are arranged such that tensioning one lead of the rope by rotation of the drive wheel causes the corresponding roller to move away from the drive wheel, forcing the other roller and the other lead against the drive wheel.
