Curtain has underlying second winding, with associated second motor, at the winding core in axial direction of winding whereby motors have opposite directions of rotation during unwinding and winding associated curtain course

摘要

The curtain has an underlying second winding (12a) with an associated second motor arranged at the winding core (11) in the axial direction of the winding (12). The two motors (M,M') have opposite directions of rotation during unwinding and winding the associated curtain course (5,5a) and support the curtain course during opposite torque with the support device (10,11a).
