The door (1) has a door plate (2) guided in a lower guide (5) and an upper guide (4) by rollers. A drive wheel (6) stays in operative connection with a drive motor and a coupling device (10). A counter wheel (8) is attached to an upper part of the plate with respect to the drive wheel. The drive wheel is brought in contact with a running surface of the plate using the coupling device, where the surface is made of metal. The plate is steadily guided between the counter wheel and a metering wheel (7), and the upper guide is formed as a brushing guide. |
