At each end there is a draw-cord plate (pulley) (7) in which the draw cord (9) is wound. Furthermore, at each side there is a guide track (11) with a configuration symmetrically matched to that of an open channel (14) on each side for a roller carriage (15), as well as a closed guide chamber (16) in which the draw cord (9) is forcibly retained. End support plates (3) engages medially with the profile of the guide track (11) and is provided with a mounting (4) which serves as a motor bearing, while the draw-cord plate (7) is rotatably mounted over the mounting (4) and the motor head (5).
