摘要:
The operation of a roller blind occurs by means of a ball cord and a pulley. The ball cord may be wound several turns around the pulley, in that oblong axial tracks have been provided in the pulley. Thereby the winding may be preserved without jamming between the windings. Greater forces may be transmitted to the pulley than in case of known constructions.
