Abstract
The selection device includes a sensor unit which checks the flatness of the free surface of a sheet pack at an edge, and which moves vertically away from and into contact with the free surface of the pack; the sensor unit extends along an axis transversal to a direction of feed and operates a blade which defines the ream and is opposite and attached to the said sensor unit, moving with the unit near to the edge, and may be positioned parallel to the free surface of the pack; drive means are envisaged for the blade, to move it from a position away from the edge until it makes contact with the ream, at which point the blade penetrates the pack, and a position in which it defines a gap between the ream and the pack, in which the blade is turned about the transversal axis through an angle sufficient to allow the transfer means to penetrate the ream.
