A device is described for unwinding a reel of web material in order to feed said material to a processing section, comprising a support (1) for the reel (B), an unwinding member and an actuator (21) which applies a pressure on the reel, causing said unwinding member to puss thereon; means are also provided for adjusting the pressure applied to the reel via said unwinding member (17) as a function of the diameter of the reel being unwound, the pressure being reduced as the diameter decreases.
