Abstract: Automatic unwinder of flexible materials wound on reels (100) comprising a support structure (2), on which at least two mandrels (3) are rotatably mounted, feeding means (4) for feeding the operating machine with at least a flexible material, defining a mouth (400), susceptible of being traversed in the advancement direction (X) of the material. The automatic unwinder further comprises at least a slide guide (5), extended between a first end (5'), in proximity to the mandrels (3), and a second end (5'), in proximity to the mouth (400), and a rack (6), at which portions of corresponding flexible materials are susceptible of being retained. The automatic unwinder further comprises at least a carriage (8), provided with a retention gripper (9), and movement means (10) in order to move the carriage (8) along at least a slide guide (5) between a grip position, in which the carriage (8) is at the first end (5') and the gripper (9) is susceptible of grippingly receive a free flap of the flexible material, and a release position, in which the carriage (8) is at the second end (5 ") to release the free flap at the rack (6).
