Abstract
A quiet drapery pull system includes an elongated track that receives a master car and auxiliary cars. The track defines a pair of curved surfaces for nested receipt of roller members of the cars to facilitate linear tracking of the cars. The cars preferably include tires that are made from a resilient material to limit noises caused by rolling contact and by slipping and dragging of the tires upon contact with surface imperfections of the track. The drapery pull system preferably includes a drive belt connected to a reversible motor and to the master car for driving the master car in each of opposite directions. The drive belt is preferably made from a resilient material to limit noise associated with contact between the drive belt and drive pulley and between the belt and the track.
