Abstract: 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.
