Method for Controlling an Elastic Extensible Screen Having a Variable Degree of Opening and Suitable Control Device

摘要

In order to control the light or air permeability of an elastic extensible screen (1) disposed between an area to be protected and an external area, and having a permeability that varies with a pulling force exerted on the screen, a motorized mechanism (3) adjusts the pulling force on the screen in response to a setpoint signal, which can be determined on the basis of one or a plurality of signals from one or a plurality of sensors (12, 14, 15), in particular light sensors.

1. A method for controlling the light and/or air permeability of an extensible elastic screen arranged across from an opening between a zone to be protected and an outer zone, the screen having a permeability varying with a traction force exerted on the screen, wherein a motorized mechanism for driving a winding tube for winding the screen adjusts the traction force on the screen in response to a setpoint signal.
