Abstract
A motorized carriage for opening/closing a screen moves along a rail by means of a friction wheel that is rotated by a motor and is in contact with at least one running surface of the rail. The contact force between the friction wheel and the running surface can be regulated by a presser means that enables the contact force to be varied according to a resistive force that depends on the load pulled or pushed by the carriage as it moves.
