    摘要： The unwinder includes an unwinding station, in which to arrange a reel to be unwound. In the unwinding station there is arranged a series of guide rollers, defining a feed path of the web material. There are also provided: a cutting member adapted to cut a web material coming from an exhausted reel; and splicing members to splice a trailing edge of a first web material coming from an exhausted reel to a leading edge of a second web material coming from a new reel. A pick-up device is configured to pick up the leading edge of the second web material from a temporary retaining element, carried by a transfer unit to transfer reels to the unwinding station.

    摘要： A foil reel mounting device (10; 40) for supporting a reel (2) of stamping foil (3) in a supporting module (1). The device is fixed to the supporting module (1). It includes a support (11; 41) having a recess (16; 46) to receive an axle (7) of the reel (2) of stamping foil (3). A retaining element (12; 42) mounted on the support (11; 41) and arranged to move between a closed position, in which the retaining element (12; 42) retains the axle (7) of the reel (2) in the recess (16; 46), and an open position, in which the retaining element (12; 42) releases the axle (7) of the reel (2) from the recess (16; 46). The retaining element (12; 42) is biased towards the closed position. Also, a supporting module (1) has at least one foil reel mounting device (10; 40) and a stamping machine (100) includes a supporting module (1) or at least one foil reel mounting device (10; 40). A method for loading and unloading a reel (2) of stamping foil (3) with such at least one foil reel mounting device (10; 40) is also disclosed.
