Control method and blind installation controlled by this method

摘要

The method involves monitoring a parameter representative of stress of a blind fabric during deployment of the fabric using a sensor by measuring torque exerted by an tube-shaped actuator on a winding tube. The fabric is rolled on the winding tube triggered automatically in response to the reduction of the stress of the fabric consecutive to block the movement associated with arms during the deployment of the fabric by the actuator. The rolling of the fabric on the tube is stopped automatically before folding the arms and after a predetermined duration. An independent claim is also included for a blind installation bracket comprising a blind fabric.
