A moving door leaf (3), capable of being formed to adopt the desired path of the door, is so arranged as to be capable of being guided at its respective lateral edges (3A,3B) by means of guides. It is attached to a door cable running between the door leaf and a balance spring arrangement (21) for the door. The cable can be wound on a cable drum (24) provided with cable grooves. - Each guide extends in the form of a spiral along a common plane and is transformed from guide sections of straight form connected to one another via curves into a guide section of curved form. The cable drum exhibits a dia. which varies over the width of the cable drum. |
