An unwinding and/or winding device (1), particularly for awnings and the like, comprising a rotating shaft (15) rotatably coupled to a supporting element (16) for the rotation of the rotating shaft (15) around its longitudinal axis (17). A flexible element (20) is also comprised, a portion (21) of which is associable with a covering sheet (6, 7) to be tightened and fixed, at a first one of its ends (22), to the rotating shaft (15) for the unwinding or winding of the same flexible element (20), respectively, from or onto the rotating shaft (15). The device (1) also comprises a slider (28) that moves with respect to the supporting element (16) in parallel with the longitudinal axis (17) of the rotating shaft (15) and is kinematically associated with the rotating shaft (15) by means of motion conversion means (29) for converting the rotary motion of the rotating shaft (15) into a translational motion of the slider (28). During its unwinding or its winding, respectively, from or onto the rotating shaft (15), the flexible element (20) is guided by the slider (28). |
