The continuous belt contained in a profiled holder (4) is connected to a door leaf (6) on its upper and lower stringer. An electrical drive unit consisting of a motor with control and gear operates in conjunction with one of the deflector rollers (17) for the belt. The drive unit and deflector rollers are positioned with the belt on an adapter rail (9) in profiling (10) on the underside of the profiled holder. The front side edge of the flat adapter rail is lug shaped for plugging in the adapter rail into a groove (12) on the underside of the profiled holder. |
