Abstract:
A roll-up video-projection screen ( 1 ) has a transverse upper casing ( 2 ) enclosing a horizontal rotating drum ( 11 ) around which rolls up and unrolls a projection fabric ( 10 ) provided at the bottom part with a weighting and tensioning element ( 30 ). The projection fabric ( 12 ) has a front projection face ( 12 ). The screen ( 1 ) includes a mechanical assembly ( 20 ) imposing, when th′e fabric ( 10 ) is unrolled, a transverse curvature to the front projection face ( 12 ). The imposed curvature of the front face ( 12 ) of the fabric ( 10 ) also exists in the unrolled position of use of the screen ( 1 ).

Claim (Index 4):
A roll-up video-projection screen ( 1 ), comprising a transverse upper casing ( 2 ) enclosing a horizontal rotating drum ( 11 ) round which rolls up and unrolls a projection fabric ( 10 ) provided at the bottom part with a weighting and tensioning element ( 30 ), the projection fabric having a front projection face ( 12 ), the roll-up video-projection screen further having an assembly of mechanical curving means ( 20 ) imposing, when the fabric ( 10 ) is unrolled, a transverse curvature to the front projection face ( 12 ), said imposed curvature of the front face ( 12 ) of the fabric ( 10 ) also existing in the unrolled position of use of the screen ( 1 ), wherein the curving means ( 20 ) comprise two transverse curvature profiles ( 21 ,  22 ) arranged in an upper casing ( 2 ), the two transverse curvature profiles ( 21 ,  22 ) including one upstream profile ( 21 ) located behind the front projection face ( 12 ) of the fabric ( 10 ) and one downstream profile ( 22 ) located in front of said front projection face ( 12 ) of the fabric ( 10 ), so that the curvature is imposed on the fabric ( 10 ) that is trapped between these two transverse curvature profiles ( 21 ,  22 ) and in that the transverse curvature profiles ( 21 ,  22 ) are curved backwards and arranged in relation to one another so that each point of the fabric ( 10 ), whatever its position along the downstream transverse profile ( 22 ), follows the same path of travel as the downstream profile ( 20 ) on unrolling the fabric ( 10 ), so that two points of the screen that are situated on the same transverse line of the screen in the rolled-up position thereof are on the same horizontal line in the unrolled position of said screen, wherein at least part of the downstream transverse profile ( 22 ) is closer to the rotating drum ( 11 ) than the upstream transverse profile ( 21 ).
