Disclosed herein is a device (1) for winding and unwinding flexible materials. The device (1) comprises a bobbin (5) and a handler (50). The bobbin handler (50) has two arms (3,4) moveably mounted to opposite ends of a support frame. The arms (3,4), are movable between a first position in which both arms (3, 4) are extended outwards of the support frame to a width greater than that of the bobbin, and a second position in which the ends of the arms rotationally engage with the ends of the bobbin (5) through the central axis of the bobbin (5). The engagement between the ends of the bobbin and each respective arm (3,4) is defined by a male conical projection (30) and mutual circular recess (17a, 17b), and in the second position the male conical projections (30) are received within the respective recesses (17a, 17b).
