Abstract: Described is a log ejection group in a rewinding machine that includes an unloading plane of wound logs and a means for slowing down the logs associated with the unloading plane. The slowing down means includes a motorized upper inlet roller to intercept the logs arriving on the unloading plane and a pair of motorized handling rollers located downstream of the upper inlet roller. The pair includes an upper handling roller and a lower handling roller. The lower handling roller is integrated into the unloading plane. The upper inlet roller and the upper handling roller are arranged on an upper structure, which is adjustable in height. The angular speed of the upper inlet roller is greater than the angular speed of the upper handling roller. A method for ejecting a log using the log ejection group is also described.

Abstract: A method for extracting a core (1) from a reel (2) of paper is described, where the reel (1) has been wound in a winding station upstream of an extraction station (100) of the core (1); the method comprises the steps of providing an extraction element (3) having an expandable element (4), shaped to enter, when in the non-expanded form, within a cavity (5) defined by the inner wall (6) of the core (1) of the reel (2), the core (1) extends according to a central axis (X) which is substantially horizontal when the reel (2) is positioned for extraction; inserting the expandable element (4) of the extraction element (3) in the cavity (5) of the core (1) on which a roll of paper (20) is wound; expanding the expandable element (4) until it engages the inner wall (6) of the core (1); pulling the extraction element (3) in the opposite direction to that of insertion, to extract the core (1) from the reel (2); bring the expandable element (4) back to the non-expanded form; extracting the expandable element (4) from the core (1). A machine (10) for extracting a core (1) from a reel (2) of paper by means of such method and an extraction station (100) for extracting a core (1) from a reel (2) of paper comprising such machine (10) are further described.
