Door i.e. sectional door, for closing e.g. garage opening, has guiding devices guiding loading branch and/or empty branch such that distance between loading and empty branches from drive wheel to opening is reduced
The door has a guidance unit (106) provided for movable guiding of a door leaf (102) between a position, in which a building opening is free, and another position, in which a building opening is closed. A drive wheel or drive pinion of a drive head is provided for driving a transmission device i.e. toothed belt, where a drive axis of the drive wheel runs in a perpendicular manner. Guiding devices i.e. channels, are attached at the drive wheel and guide a loading branch and/or empty branch such that a distance between the branches from the drive wheel to the opening is reduced.
