(57) A device (1) for keeping an insect screen (11) that can be rolled up distended during
rolling and unrolling; the device (1) is installed within a casing (10) designed to
house at least one winding roller (12) on which the screen (11) is rolled up; the
device (1) possesses a flexible structure (2) having fixing members (5) for guaranteeing
a fixed positioning within said casing (10) and comprises at least one roller (7)
rotating on a shaft of its own, which is installed on a pair of supports (6) projecting
in cantilever fashion from the structure (2), and is able to turn with respect to
said structure (2), which is always in physical contact with at least one portion
of screen (11) that is rolled on said roller (12) as a result of the flexibility of
said structure (2); the roller (7) moreover has a lateral surface that develops in
a plane parallel to the surface of the screen (11); the structure (2) is flexible
in a direction orthogonal to the axis of the roller (7).
